Lung Cancer Symptoms, Diagnosis, Treatment and Risk Factors
- Symptoms: Symptoms of lung cancer may include developing a new cough or experiencing a persistent cough; coughing up blood; dull, persistent pain in your chest; shortness of breath; wheezing or hoarseness; and repeated respiratory infections, such as bronchitis or pneumonia
- Diagnosis: Diagnosis tools may include an X-ray, CT scan, bone scan, and examination of mucus or lung fluid. To confirm a lung cancer diagnosis, your doctor will usually perform a lung biopsy. If the lung biopsy confirms cancer, other tests will be performed to determine the type and how far the cancer has spread.
- Treatment: Treatment methods for lung cancer may include surgery to remove a portion of a lobe, a full lobe, or an entire lung; radiation; chemotherapy; laser therapy; and biologic therapy.
- Risk Factors: The main risk factor for lung cancer is smoking and other tobacco use. Other risk factors include exposure to second-hand smoke, exposure to asbestos or radon gas, presence of chronic obstructive pulmonary disease (COPD), having a relative with lung cancer, prior history of lung cancer, and prolonged exposure to highly polluted air.
