Nearly a quarter of a million lung cancer cases are newly diagnosed each year. Nearly one out of every 14 men will be diagnosed with this condition. Lung cancer is the number one cause of cancer in men and is the number five cause in women. Lung cancer is more common in women than breast cancer. Cigarette smoking is the primary risk factor for this illness. Passive smoking also can lead to lung cancer. Small cell and non-small cell cancer are the two most common types of lung cancer. Long term survival rates for this disorder are very low. Tumor types include epithelial cell source, pleural source and cancer of the supporting tissues of the lung, including the blood vessels. Never smoking is the best protection against this disorder, and do not allow yourself to be exposed to smoke.
The causes of cancer are complex and complicated but the disease can be caused by environmental toxins, heredity of certain types of cell precursors that can lead to cancer, or exposure to smoke.
Chest X-ray and chest tomography are the two initial tests for lung cancer to locate and visualize the tumor. Biopsy and further imaging studies may be required to clearly identify the tumor type.
Treatment is usually a combination of radiation and chemotherapy. A specific course of treatment will be devised to treat the specific type of cancer cell that is found in your lungs. Your provider will review the results of your tests, explain the type of cancer that affects your lungs, and devise your course of therapy.
