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.
