W ith the exception of skin cancer, lung cancer is the most common cancer in the United States. Early detection of lung cancer is very difficult because many of its symptoms, including persistent cough, blood-streaked sputum, chest pain, or recurring pneumonia, seldom appear until the disease is in an advanced stage.
Smoking is the leading risk factor for lung cancer.
Medical experts agree that the most important way to decrease your chances of getting this disease is to not smoke. Smoking encourages abnormal cellular growth patterns that can develop into cancer. If you quit before pre-cancerous changes occur, however, the chances are good that your bronchial lining will return to normal. All rights reserved.
