With 164,000 new cases in the United States and 20 600 new cases diagnosed each year in Canada, lung cancer is the most common cancer in North America. Although the prevalence ranks under the breast and prostate cancer, lung cancer is the leading cause of cancer death in the United States and Canada. United States, survival rates five years years for lung cancer is relatively low at 14Percent and the number has increased by 50 percent if the cancer is diagnosed early. Lung Cancer Symptom

The major risk factor for lung cancer is smoking, the behavior that the cases are 85 to 90 percent of all. The long-term exposure to secondhand smoke also causes lung cancer. The risk factors are more important than exposure to carcinogenic chemicals at work, in particular organic chemicals such as asbestos and vinyl chloride. Exposure to air pollutants and other gases and radonincreases the risk of lung cancer, especially in the face of smokers.
Lung Cancer Symptom
The oxygen enters the blood through a series of tubes and passages in the lungs. E 'in what is called respiratory bronchioles in the branches of division is subdivided into smaller ones. At the end of the bronchioles, alveoli, air bubbles that are known. Most lung cancer begins in the lining of the respiratory system, cancer can also start in the alveoli, trachea, bronchi, o. About 20 percent of patients with lung cancer was small cell carcinoma, a type of lung cancer usually starts around the airways. Squalor carcinoma often occurs in the vicinity of the bronchi. It contributes about 30 per cent of cases of lung cancer.
Lung Cancer Symptom
Lung cancer is often early in the. Patients may develop a cough or a finding that the deterioration of chronic cough. OtherThe symptoms> include chest pain, shortness of breath, hoarseness, coughing up blood from the respiratory tract fluids and frequent bouts of bronchitis or pneumonia. Sometimes, the first symptoms of lung cancer are bone pain, headache, dizziness, or other diseases that have metastasized signs.
People with warning signs should consult their family doctor can assess the symptoms and cancer patients to find doctors in the specialty.A doctor is the first in the history of the disease on the patient's current symptoms, medical history, and family members diagnosed with cancer. The test procedure used for the physical symptoms of patients in clinical and food may include a digital rectal exam, where doctors a gloved finger gently to ensure the regularity of the rectum. The medical examinations can be performed on the breast in women with breast was considered softfeel a lump or a mass that is not unusual.
During the test, the doctor may use a thin tube called an endoscope to blow the tumor in the eye of the inner cavity of the body, etc.. Endoscopic procedures are used on the body or body cavity search, it depends. In gastrointestinal endoscopy, the doctor, a special endoscope inserted in the throat to examine the layers of the stomach, esophagus and the first part of the small intestine. A colonoscopy is a flexible tool to learn more about the length of noticeColon.
can contribute to a series of laboratory tests narrow the diagnosis. In a Pap test, the epithelial cells of the cervix with a plastic brush to remove. These malignant cells are examined under a microscope for cell changes that there is no evidence that cancer can develop as a character. If clinical signs suggest that patients with bowel cancer, blood test, doctors can be found in the stool with occult blood in the stool. A small stool sample is spread on paper with a coating of the patientChemical called guaiac, which reacts with blood. The maps were analyzed in the laboratory for occult (hidden) blood. Other tests for signs of the tumor, the chemicals in higher levels of certain types of cancer, if any. For example, a prostate specific antigen (PSA) test measures the level of prostate specific antigen in the blood.
These include computed tomography (CT) and magnetic resonance imaging (MRI). CT and MRI uses a computer to form three-dimensional images of the tumorand surrounding tissues. Called X-ray mammography images to help clinicians detect and evaluate breast cancer breast cancer. High frequency ultrasonic sound waves bounce off the scanning of the tumor and the tissue surrounding the tumor to create an image. multimodality display technology combines images from multiple imaging devices into a single image, including the latest three-dimensional images with a lot more detail. diagnosis computer technology with sophisticated computer program calledartificial intelligence to analyze the X-ray mammography and to seek help for signs of cancer and offers an automatic second opinion.
