Heart disease, lung cancer and COPD - The three causes of death

Lung Cancer Symptom

Smoking, including cigarettes, cigars or pipes is closely linked to the development of diseases such as heart disease and lung cancer. In addition to these serious diseases, smoking can also be the cause of COPD (chronic obstructive pulmonary disease).

Lung Cancer Symptom

This condition causes inflammation and damages the tiny air sacs (alveoli) in the lung tissue and usually causes some form of respiratory disease. COPD is usually a combination of chronicChronic bronchitis and emphysema.

Lung Cancer Symptom

Because smoking is the leading cause of chronic bronchitis and emphysema, two conditions often occur together in the same person.

Lung Cancer Symptom

Damage from COPD is both progressive and permanent. It 'has become a serious health problem and health statistics, is the fourth leading cause of death in the United States. Because of the severity of these diseases, it is urgent for those who smoke to quit.Understanding the causes and symptoms of COPD is vital to try to encourage smokers to stop this potentially deadly habit.

Chronic bronchitis is an inflammation of the bronchioles and the tube is usually caused by inhaling bronchial irritants like cigarette smoke other, exhaust fumes, chemicals, air pollution and other environmental factors such as mold or dust.

Smoking may increase the risk of infection because they damage the hair as smallProjections (cilia) that protect the lungs against bacteria and other foreign materials into the lungs.

Diagnosed with this disease can develop slowly, middle-aged and older, the more risks with him. The symptoms of bronchitis can also be things such as dyspnoea, cough, sputum, chest pain when coughing or shortness of breath and persistent fatigue.

Emphysema is a chronic disease on the other side of the airway. Therecharacterized by expansion or the loss of elasticity of the alveoli or air sacs, and perhaps the collapse of the bronchi, the airways, the first, which no longer contain cartilage.

If this happens, reduce the exchange of oxygen and carbon dioxide gas in the alveoli of the lungs and lungs from working properly can reduce their ability to breathe when you lose. This reduces exhalation may also reduce the amount of air that can be inhaled. Because ofThis carbon dioxide, the exhaust gas is not quite out of the lungs and oxygen-rich air can not be recovered. Because of this problem could be with emphysema breathe hard and often to gasp for air. Emphysema is most common in people over 50 years and can coexist with other respiratory diseases like bronchitis.

What are the real causes and symptoms of COPD?

The risk factor is more important is a lifestyle of smoking. It does notDifference if you smoke cigarettes, cigars or pipes. Even the fumes from chemicals, detergents, aerosols, air pollution, dust and pollutants aggravate symptoms.

Chronic bronchitis is more common in people over 40 years, whereas emphysema is more common in people aged 60 years.

Some types of work (socio-economic class) can play a role in COPD. Deaths from COPD are approximately two times higher among unskilled and semi-skilled thanprofessionals.

Family history and genetics may predispose people in certain families to develop COPD, while other causes such as smoking and air pollution are also available.

There is an effective treatment of COPD?

The treatment of COPD is closely dependent on the overall health of the patient and the severity of the disease.

In general, a health program includes breathing. Disability and other symptoms can be alleviated and thus reducethe occurrence of early death. However, there are no treatments proven to cure this disease. The treatments were designed only to relieve symptoms and improve survival rates.

Instead of focusing on healing for which there is none, if the changes in lifestyle that can prevent the development of COPD are underlined. COPD can be prevented if people who smoke, quitting smoking, maintaining a good diet, drink plenty of fluids, maintain an appropriate weight andExercise regularly.

Understanding the health risks of COPD and potentially fatal, and are essential to convince smokers to quit smoking.

What is Lung Cancer - Incidence, signs, symptoms, causes, prognosis and therapy

Lung Cancer Symptom

INTRODUCTION

Lung Cancer Symptom

Lung cancer may also be the most tragic cancer because in most cases, could have prevented 87% of cases are caused by smoking. Lung cancer has long been the leading cause of cancer death in men and 1987 also the leading cause of cancer death in women. This is the second most common form of cancer in most Western countries, and although the lung> The incidence of cancer is less common in developing countries is rapidly growing popularity of smoking will see the number of people living in these countries to achieve quickly with the Western world.

Lung Cancer Symptom

Lung cancer can occur in any part of the lung, and 90% -95% of lung cancers are expected to arise from epithelial cells of the airways or large and small mucosal (bronchi and bronchioles), for Therefore, tumors lung aresometimes called bronchogenic carcinoma or lung cancer.

Lung Cancer Symptom

The most common are cancer, small cell carcinoma, adenocarcinoma and squamous cell carcinoma of large cells.

Many experts agree that the lung cancer caused by inhalation of carcinogenic pollutants by a susceptible host is. Who is most vulnerable? Every smoker over the age of 40 years, especially if they start smoking before the age of 15, smoked 20 or more years 20 or worked with or nearAsbestos. Two other factors increase susceptibility: exposure to carcinogenic industrial and air pollutants, and the family susceptibility (asbestos, uranium, arsenic, nickel, iron, chromium, radioactive dust and coal dust.).

Signs and symptoms

Since the early lung cancer is usually asymptomatic, the disease is often advanced at the time of initial diagnosis. Advanced signs are: squamous cell carcinoma with small and smoker's cough,Pain hoarseness, wheezing, dyspnea, hemoptysis and chest. With adenocarcinoma and large cell carcinoma, fever, weakness, weight loss, anorexia, and shoulder pain. In addition, the production of hormone that regulates various body functions also be affected.

DIAGNOSIS

Diagnosis requires chest x-ray sputum, cytology, CT, bronchoscopy examination of pleural fluid and biopsies. Other tests to detect metastasis include bone scan, a bone marrow biopsy and CT scans ofBrain and stomach.

METASTASIS

The disease spreads most commonly to the liver, adrenal glands, bones and brain. Cancer that has metastasized to the bone causes bone pain, usually in the spine (vertebrae), femur and ribs. Cancer that spreads to brain may be difficulties with vision and weakness on one side of the body.

Cancer can develop in some nerves in the neck, hanging from an eyelid, small pupil, sunken eyes,and reduced perspiration on one side of the face that are along these symptoms, such as Horner's syndrome (see Autonomic Nervous System: Horner's syndrome). It may grow directly into the esophagus, or it can develop in the region and the pressure on them, causing difficulty swallowing. It can also be transmitted by blood to the liver, brain, adrenal gland, spinal cord and bone.

TREATMENT

Treatment depends on the type of cancer cell-specific, to what extent ispropagation, and the condition of the patient's benefit. If studies of lung cancer, CT, and often the positron emission tomography (PET) are used to ensure, to determine if the disease is localized and accessible to surgery or if it is to the point where it can be treated surgically released. Treatment is usually a combination of surgery, chemotherapy and radiotherapy.

Surgery is usually the first option. Chemotherapy can be used as first-line treatment or usedadditional treatment after surgery. Radiation therapy can be directed to the tumor from outside the body (external radiation) or may in needles, seeds or catheters placed, and placed in your body near the tumor (brachytherapy). Radiation therapy may be used alone or in combination with other cancer treatments. Radiotherapy can also be used to reduce the side effects of lung cancer.

Treatment may not be as effectivePatients with bone metastases or liver, lung, loss of excess weight, smoking, persistent or pre-existing conditions like heart disease or emphysema. At some point, however, you and your oncologist or the family that the treatment is not advisable, palliative care can provide comfort.

Lung Cancer Symptom

Not only that asbestos causes lung cancer mesothelioma

Lung Cancer Symptom

Mesothelioma lung cancer is usually exposure to asbestos. In fact, there are many other risk factors that cause cancer, mesothelioma. One of them is the Erion. Erion is a mineral naturally occurring, fibrous, to include a group of minerals called zeolites. Zeolites are aluminosilicates of alkali and alkaline earth hydrated.

Lung Cancer Symptom

Erion has been tempered in the past used as a precious metal catalyst in a hydrocarbon cracking process.It 'been studied for the use of fertilizers and odors in animal control, because of its ability to selectively adsorb molecules of air or liquids. Erion blocks used in many countries were (and still can be used), building materials or pulp and lime plaster.

Lung Cancer Symptom

Erion has been identified as a risk factor for lung cancer mesothelioma in 1975, when the turkish government has presented a rare malignant one study revealed a high incidence ofMesothelioma lung tissue of people in some villages in the mountainous region in the center of the Cappadocia region in Turkey. In two small villages of mesothelioma lung cancer accounted for 43% of deaths for 23-year duration of the course. Erion fibers were found in biopsies of lungs of the mesothelioma cancer afflicted. Comparing this show to a rate of 9.7% of deaths from this disease among asbestos insulation installers, that this anomalyCondition was.

Lung Cancer Symptom

Other studies have shown Erion causes similar diseases in laboratory animals. When researchers from the mountain. Sinai Hospital in rats injected with the same dose of Erion, they used asbestos in rats do not live long enough to mesothelioma cancer. At a dose significantly reduced in mice with cancer - Erion. Mineral is probably the most known toxic milligram of fibers in the lungs is a death.

Erion's now considered so dangerous thatEPA requires that all persons who produce, import or process any article containing EPA Erion record 90 days in advance. This gives the EPA to consider the possibility of limiting or prohibiting the activity.

Erion has been removed or is no longer on the market for commercial purposes.
Although many other commercial uses of natural zeolites (litter, soil, feed, water, sewage, gas absorption agents, etc.) So, the potential exposure to occur during Erionproduction and
Extraction of the zeolite.

And there are questions:

There are other hazards such as asbestos and mineral Erion?

Can we expect lung cancer from exposure to asbestos mesothelioma not only increases by a 20 to 30 years?

Not only that asbestos causes lung cancer mesothelioma

How smoking causes lung cancer

Lung Cancer Symptom

It 's good for the entire second half of the 20th century known that smoking causes lung cancer. Smoking not only increases the risk of lung cancer in smokers, but the risk of esophageal cancer, pancreatic cancer, cancer of the cavity Oral, laryngeal cancer and renal cancer is also increased. These tumors are expected to increase for women because of increased levelsSmoking.

Lung Cancer Symptom

The intensive use of tobacco leads not only the various types of cancer, but also increases the risk of many cardiovascular diseases. In Central and Eastern Europe, more than 400,000 premature deaths from smoking each year. The current level of lung cancer in young men in Central and Eastern Europe is bigger than ever. Smoking is unfortunately still in Central and Eastern Europe and China whereTobacco related deaths are very fast. Lung cancer is cancer related to smoking and major leading cause of cancer death in men in almost all developed countries. Because lung cancer is often fatal, mortality, and consequently so are the social costs.

Lung Cancer Symptom

Smoking among women has increased dramatically. More and more women smoke cigarettes in the world. For many years it seemedthat rates of lung cancer, and where the tobacco was less with the same effect for women than for men there. But that is now proven wrong and there is no evidence that the risk of lung cancer in smokers is higher among women than in men A lot of time between exposure and effect. Cancer Lung cancer now surpasses breast cancer as the leading cause among women in Canada, the United States, Scotlandand many other countries.

Lung Cancer Symptom

Cigarette smoking kills half of those who accept the habit of using half of all deaths in middle age and any loss of more than 20 years life expectancy of smokers. Lung cancer is obviously the most common cause of death, but the smoke can cause death in 24 different ways. Smoking among men has decreased, while it increased among women. And the rates of lung cancer and increases in womendecrease among men. Tobacco is an addictive substance, there is no such thing as a cigarette "safe" should, believes in young adults not to smoke or smoking should be assisted will be asked to stop. Hopefully one day in the future, we can say, and how smoking causes lung cancer ", not" how smoking causes lung cancer. "

Lung Cancer - Causes, Types and Symptoms

Lung Cancer Symptom

Lung cancer usually starts forming at the center of fifty or sixty. Tobacco addiction is responsible for 80% to 90% of cases. The Canadian Cancer Society, says that in 2010 its 24 100 new cases in the country: 12 900 11 200 men and women.

Lung Cancer Symptom

Cause
* Tobacco addiction.
* Exposure to smoke in high school.
* Exposure to carcinogenic particles in the air as those who for some asbestos in some arsenicof air pollutants or radon gas (carbon monoxide, ozone, etc.).

Lung Cancer Symptom

Types
There are two types of lung cancer. They grow and spread differently in the body.

Lung Cancer Symptom

* Small Lung Cancer (SCLC). This is the most dangerous form. Over 20% of cases in this form. At diagnosis, the risk that the cancer has already spread elsewhere in the body are high. It grows quickly and is often impossible to deal withthrough surgery. Instead, they use chemotherapy and radiotherapy.
* Non-small cell lung cancer (NSCLC). This form, which represents about 80% of cases, easier than the first treatment. It grows slowly.

Symptoms

Sometimes the symptoms are not detectable. The most common symptoms are the following. However, health problems, other symptoms that arise.

* Cough or increasedthat does not disappear (it is necessary to take account of smoker's cough, which worsened).
* The constant pain in the chest, which are larger if they are coughing or deep breathing.
* Gasp.
* Shortness of breath.
* Spits blood.
* This item is for more than 3 or 4 weeks hoarse.
* Depending on the circumstances: bronchitis or pneumonia, repetition, weight loss, chronic fatigue, headaches ...

Lung Cancer Symptom

The lung tissue is caused by the uncontrolled growth of cells rapidly this type of cancer is more common and results in more than one million deaths a year. This form of cancer is due to the weight loss or coughing up blood or breath is extraordinary. It can be observed X-ray of the chest, like a scanner. The treatment you get depends on the phase we're in cancer treatment include surgery, chemotherapy andRadiotherapy.

Lung Cancer Symptom

CLASSIFICATION

Lung Cancer Symptom

cases of lung cancer classified microscope after studying with them. Classification is necessary because different types of cancer are treated differently. most lung cancers are - the small cells grow. Malignant tumors of the lung cancers are classified into two types is not small and small cell lung. Epithelial cells of small cell lung carcinoma, non-cancer andCarcinoma of 4 and 16% 80th 8% incidence of lung cancer, respectively.

Lung Cancer Symptom

First non-small cell lung cancer

Squamous non-small cell lung cancer are grouped by their prognosis and management are equal to a certain extent. , Adenocarcinoma and large cell carcinoma of the lung cancer cells are also classified into three types:. Squamous lung cancer cell lung carcinoma occurs near acentral bronchus. They account for 25% of lung cancers. Adenocarcinoma begins in the peripheral lung tissue. The case of adenocarcinoma are the consequence of smoking. It represents cell lung cancer Non-small 40%.

Second-small cell lung cancer

This type of lung cancer is rare. A cancer is sometimes called "cell" oats. Most of the time the large airways (bronchi of primary and secondary) aretherefore, grow at a rapid pace. This type of lung cancer for smokers with multiple partners.

The secondary tumors

These tumors are classified according to the original site of cancer such as breast, lung, but it has spread. The majority of lung cancers in children are secondary.

Staging of lung cancer

staging of lung cancer is used to assess the degree of proliferationCancer from its original location. It 'an important factor that determines the potential treatment of cancer of the lung cancer. The level part from 1A to 4, with a better prognosis 1A and 4 is the worst.

AND SYMPTOMS

The symptoms of lung cancer: a hoarse voice for ever. 2. Sudden weight loss. 3. Feeling pain in the chest or abdomen. 4. Swallowing. 5. Loss of appetite. 6. Running outBreath. Many of these symptoms are not specific. Over time, they develop symptoms or signs, the cancer has already spread from their place of origin. Very few people with this cancer have signs in the diagnosis, tumor stage for this curve observed on routine chest radio.

CASES

The three leading causes of cancer are carcinogens (found in tobacco), viral infections, and ionizing radiation. In the case of exposure, which causesChanges to the DNA in the tissues of the bronchi of the lungs. With more accessible and tissue damage, suffering from cancer.

1. SMOKING

Smoking is the leading cause of cancer. In a cigarette there are 60 different types of known carcinogens such as nitrosamines and radioisotopes. Smoking is responsible for 80% of cases. The risk is generally lower in non-smokers. When a person smokes a potential for increasing the proportionthis type of cancer. There have been cases where a person stops smoking, damaged cells are gradually repaired. In non-smoking, passive smoking is the leading cause of lung cancer -. cancer from passive smoking is another person a smoker inhales a.

2. Radon

The gas produced by the decay of radium. This gas is odorless and colorless. exposure to ionizing radiation, genetic material, mutations that sometimes turn to cancer. Exposure to radonGas is the second leading cause of cancer - lung cancer after smoking.

3. ASBESTOS

Asbestos is responsible for the development of several cancers, including lung cancer is one. In Britain, the accounts of asbestos for 2-3% of all cases of this type of cancer.

4. VIRUS

Viruses are responsible for the onset of cancer - lung cancer in animals. And research has shown similar potential in humans.

5.PARTICLES

has a direct connection to the cases of lung cancer. The size and number of dust particles in the air determines the risk of lung cancer -. When increasing the concentration of particles by more than 1%, then it is likely that increased by 14%.

Pathogenesis

Like other forms of cancer, suppression of lung cancer started with the activation or deactivation of tumor ocnogenes Genes. Ocnogenes are genes that make people more susceptible to cancer. Ocnogenes proto-ocnogenes when exposed to carcinogens of certain products. In K-ras proto-oncogene mutation occurs, adenocarcinomas account for 10-30% of the lung. Tumor invasion, angiogenesis, apoptosis, cell receptors, the configuration of the profile of the epidermal growth factor-regulated. Mutations and amplification of EGFR are common in lung cancer non-small cellCancer>. The basis of treatment with EGFR inhibitors are also provided by the mutation and amplification of EGFR. chromosomal damage can cause loss of heterozygosity, which may cause the inactivation of tumor suppressor genes result. Damage to four of these chromosomes, 13 and 17 5q qp often. Lung cancer affected 3p p53 tumor suppressor gene on chromosome 17p is in most cases, with small cells. c-Met, NKX2-1, LKB1, and PIK3A also mutated BRAF orstrengthened. Several genetic polymorphisms are in addition to cancer. Some of them include polymorphisms of genes for interleukin-1, cytochrome P450, the promoters of apoptosis such as caspase-8 and XRCC1, a molecule of DNA repair. People with these polymorphisms are more likely to develop lung exposed to carcinogens. Research has shown that MDM2 309g allele a risk factor for the development of this low penetrationAsians.

DIAGNOSIS

If a subject reported symptoms that may indicate lung cancer, chest x-ray is then performed in the first phase. The test shows the expansion of mediastinium, atelectasis and pleural effusion. Although there are no findings radio chart, but the indication is high, because things like the person, a heavy smoker with blood-tinged sputum, and then the scanner can provide the required data. If the results arenatural in sputum cells, and increases the risk of this cancer. sputum cytology can be performed by combination with other screening tests. The differential diagnosis for patients showing ECG irregularities on breast cancer included in the lung with non-malignant diseases. This point of view of infectious causes such as tuberculosis or pneumonia. The above diseases mentioned above can lead to lung cancerNodules.

PREVENTION

Prevention, as always, is better than cure. steps in this direction may have cancer adopted by countries through the identification of carcinogens in tobacco and prohibit, but the lung is the main cause is still common. The elimination of smoking first hand target in the prevention of lung cancer. Steps to reduce passive smoking have a ban on smoking in public places and workplaces also taken. NewNew Zealand is limited to smoke in open spaces. A similar approach is also adopted in Chandigarh, India. Bhutan is smoking since 2005, are punishable.

PREVENTION

Screening is used to detect the symptoms of the disease through medical examinations, if the patient does not show. chest radio or graphics are screened for lung cancer. But the results have shown that screening tests for lung cancer has rarely shown anycan benefit.

TREATMENT

The treatment of lung cancer can occur in the following ways, depending on the stage or tumor grade:

1. Surgery

When doctors discovered lung cancer, and CT and positron emission tomography are commonly used to check if the illness and surgery, or may be, it was possible to the point where surgery is not. The operation may be performed ifSpirometry showed good pulmonary reserve, but if it's bad, then surgery is not possible. Even an operative mortality rate of surgery 4 4%, but because the factors of patients, lung function, and others.

2. CHEMOTHERAPY

Chemotherapy combined with radiotherapy, is used for the treatment of small cell carcinoma. Chemotherapy is also used primary metastatic non-small cell lung cancer.

3. RADIOTHERAPY

Radiotherapy,with chemotherapy is given if the patient does not fall under go surgery. This type of radiation at high intensity is called radical radiotherapy. version of the map (continue hyperfractioned accelerated radiotherapy) of this technique is given a high dose of radiation for a short period refined. In cancer has a short section of the bronchi and brachytherapy is given.

Epidemiology

Lung cancer is the mostsaid cancer. There is a 35 million cases a year and 18 million deaths. Developing lung cancer years who have a history of smoking for a long period of i. E 50 and older. In addition to smoking, passive smoking is also a factor that causes cancer of lung cancer. In addition, emissions from factories, cars, plants are a threat to human health. Lung cancer is detected, are UVB interaction with sunlight andExposure. This occurs the effect of vitamin D in the skin during exposure to the sun.

Lung Cancer - Causes, Symptoms and Treatment

Lung Cancer Symptom

Lung cancer is the malignant transformation and expansion of lung tissue, and is the most deadly of all cancers worldwide responsibility for 1.2 million deaths each year. This is a major cause of cancer death among men and women in the United States. Cigarette smoking causes lung cancer the most. More cigarettes smoked per day and the earlier you start smoking, the risk of lung cancer. High levels of pollution, radiationand also increase the risk of exposure to asbestos. There are several types of lung cancer. Each type of lung cancer grows and spreads differently and treated differently. The treatment also depends on the stage, or as he advanced.

Lung Cancer Symptom

L ', chemotherapy, radiotherapy and surgery. Lung cancer that starts in cells of lung cancer is the primary tumor, but may extend tothe lungs to other parts of the body. Metastatic colorectal cancer) often spread to the lungs than breast, colon, prostate, kidney, thyroid, stomach, cervix, colon, testis, bone and skin (Melanom. Other 90% of lung cancer early primary bronchi, lung cancer is cancer of the lung per se. The particular forms of lung cancer are small cell carcinoma, squamous cell carcinoma, large cell carcinoma andAdenocarcinoma. The last three types of lung cancers are often called non-small cell lung. Alveolar carcinoma arises in the small air sacs of the lungs (alveoli). Although cancer cellular site can be lonely, for one, often develops in various areas of the lung. Less common are the bronchial carcinoid tumors of the lung (which can cause cancer or cancer), and hamartoma chondromatous sarcoma. Lymphomais a cancer of the lymphatic system, you can start in the lungs or spread them.

Lung Cancer Symptom

Lung cancer is the rapid growth of abnormal cells in the lungs. You can start anywhere in the lungs and affect any part of the airways. When we breathe, the lungs with oxygen, the cells need to live our own conduct and their normal functions. When we breathe, the lungs get rid of carbon dioxide, a waste productcells of the body. Tumors that originate in the lungs are divided into two major categories, non-small cell lung cancer and small cell lung, depending on how the cells under a microscope.

Mesothelioma: what it is, its causes and treatments

Lung Cancer Symptom

What is mesothelioma what he does, and how is mesothelioma treated? Mesothelioma is actually a form of cancer that begins in the mesothelial lining of the heart, lungs, or stomach. Mesothelioma is a rare tumor most commonly the lungs and is caused by exposure to asbestos. Asbestos is made up of tiny fibers that are commonly used to produce insulation in homes, schools and other buildings.

Lung Cancer Symptom

Asbestosis

Lung Cancer Symptom

In addition,for mesothelioma, asbestos is the threat of arbitrary diagnosis of lung cancer, the risks that others can also often attributed to smoking o. Asbestosis, a disease of the lung tumor is not the result of the constant production of asbestos and other types of cancer is one of the larynx (throat) and kidneys.

Lung Cancer Symptom

Abdominal or peritoneal mesothelioma occurs frequently in people with a description of extreme and frequent contact with asbestoswhich usually developed asbestosis. This means that pleural mesothelioma occurs frequently in people exposed to low frequency of these fibers and did not develop in early asbestosis.

A number of symptoms of mesothelioma can take years to appear and vague in nature. Many of these warning signs are up-aging and may be used against misdiagnosis. So if you or someone you know, have a known risk of asbestos and signs ofpersistent pulmonary complaint, you should definitely see a doctor and have it in your little secret. Once again, real danger here, the symptoms are very similar to those of aging, and many of us are probably difficult to ignore, and signs or symptoms appear threatening. This brings us to the next topic.

Symptoms

diagnosis of mesothelioma in early stages is often very difficult becauseThere are various conditions to produce similar symptoms. What are the signs of a gradual Mesothelioma? Many people with mesothelioma complaining of shortness of breath and chest tenderness - especially under the ribs, but other signs and symptoms may include:

- The pain at the site of origin

- Difficulty in swallowing

- Inflammation of the throat with facial

- Weight loss, cough

- Respiratory tract infections

- Negative digestiveand / or bowel problems

- Chest pain (which is an accumulation of fluid and sometimes a reference to pleural mesothelioma)

Your doctor should perform an X-ray or magnetic resonance for anyone who established contact with asbestos in these indicators. -According to the results of your x-rays of your indicators, your doctor MDCT is usually an MRI to determine if there is growth, scanning aMesothelioma. Also note that the shortness of breath and chest pain are due to increased fluid in the pleura, sometimes indicators of mesothelioma, but signs of peritoneal mesothelioma are weight loss and abdominal pain, add the following accumulation of fluid in 'abdomen edema include others. Symptoms of peritoneal mesothelioma can:

- Intestinal obstruction,

- Abnormalities of blood coagulation

- Anemia (anemia)

-Fever

These conditions could be the result of a serious or less followed mesothelioma asbestos cancer and the fact that the symptoms of mesothelioma usually occur several years after exposure.

A dependent peritoneal or pleural organic cause (s), the liquid can seep into surrounding areas, like the space inside the chest and may have symptoms similar to congestiveDefault. (Swelling, swollen limbs, obesity), the symptoms slowly rise to the most sensitive to the call of the doctor patient intercession. With the worsening of the disease has caused the first signs are usually vague and tenderness in the chest, shortness of breath, but less common than cough.

Okay, you might think, if I - What is the treatment? This is a useful question, but may be subject to the responsesthe growth phase of the disease. Early diagnosis of cancer can lead anticancer drug treatments, including chemotherapy and subsequent stages, treatment may also use this intervention in addition to radiation. Therefore, the scenario goes like this - the medical diagnosis is made ​​after a physician (usually a biopsy of the kind), which will probably send an oncologist (cancer specialist) special close to the next. The doctor is the best treatment for yourSituation. It may not be such as chemotherapy or radiotherapy may shrink the tumor. On the other hand, can be a surgical procedure with the other two. Only a doctor can tell. It boils down to this: just been diagnosed with a terminal cancer of Art, you have a choice in this case, you can do better, and for some time. All these risks are likely.

Lung Cancer Symptom

esophageal cancer can grow anywhere. It may be in nearby lymph nodes, trachea and major blood vessels in the chest, and other surrounding organs. Treatment of mesothelioma cancer of the esophagus depends on a number of factors, including preciseLocation, size, scope and nature of cancer cells. It 'also important to verify a treatment plan for the overall health of every patient needs to develop fitness, and age.

Tumors of the

squamous cell carcinomas occur in cells lining the esophagus. adenocarcinomas propagation occurs in the glandular tissue in the lower esophagus and can spread to other parts of the body.

Symptoms of esophageal cancer mesothelioma cancer

Difficulty swallowing, a feeling of fullness,Pressure or burning of food decreases the esophagus to get a feeling of food stuck behind the breastbone.

Diagnostic Methods

Esophagus (barium), is a series of x-ray of the esophagus. To prepare for this test, the patient drinks a barium solution. Barium occurs in X-rays, coats for a better look inside the esophagus. Esophagoscopy is a thin, flexible, lighted instrument (endoscope) that crossed theMouth and throat into the esophagus down to see where it ends the esophagus to the stomach. A biopsy is a sampling of a small amount of tissue through the endoscope for cancer-test for the presence of.

Staging

The nature of the tumor is primarily evaluated by computed tomography of the chest. The scan will show whether the cancer has gone into the trachea (windpipe) and large blood vessels or lymph nodes.

Esophageal ultrasound is similar to esophagoscopy, but with theIn addition to developing an integrated ultrasound.

PET can be used to evaluate esophageal cancer as well.

Treatmen t esophageal cancer mesothelioma

The treatment of esophageal cancer depends on several factors, including the exact location size, scope and nature of cancer cells. The doctor also considers the patient's age and overall health, and develop the best treatment plan.

Surgical resection(Distance) tumor is the preferred treatment. Recently, surgeons have less invasive surgery to remove cancer of the esophagus.

Chemotherapy and radiotherapy are often used in combination with surgery or another.

Several options are available, including laser treatment, stenting, or photodynamic cancer therapy. For most patients can eat their ability to be restored in a satisfactory way with these procedures.

Amultidisciplinary team: gastroenterologist, surgeons, oncologists (cancer specialists), radiation oncologist, nurse, dietitian and social worker to join facilitate the care and outpatient treatment.

The causes of lung cancer

Lung Cancer Symptom

If people think that lung cancer, often combined with smoking. In fact, this is a major cause of illness.But this is not the only factor.

One of the most important goals of research for health care for this disease is a genetic factor. Most tumor cells develop, if there is an error in the transfer of DNA from cells. This error may also be influenced by other environmental factors that have led health experts to examine the statements of external factors that may contribute to the formation of cancer cells.

Asbestos was too much has been mentioned as a keyenvironmental factor that causes the disease. Asbestos is a type of artificial mineral fibers grouped and occurs naturally in the environment. These fibers, when a person is exposed to inhaled into the lungs to get caught in one and collect up to cause inflammation of the lungs.

Another crucial factor that could lead to the development of this disease is the inhalation of smoke.
