It is hard to detect lung cancer in its early stages. There are usually no symptoms with early lung cancer. Signs and symptoms that might indicate lung cancer include persistent cough, phlegm streaked with blood, recurring pneumonia or bronchitis, and chest pain. Chest x-rays and analysis of cells in the sputum are usually the first tests if there is a suspicion of cancer. These tests are not used unless there are abnormal chest x-ray findings or symptoms.
Treatments depend upon the type and stage of the cancer.
Options include surgery, radiation therapy, and chemotherapy. For localized cancers, surgery is usually chosen. Radiation and chemotherapy are often used in combination with surgery. Once discovered, lung cancer usually has a poor forecast. Prevention of the disease is crucial.
