If you are experiencing a medical emergency, contact your local emergency services immediately.
Overview
Lung cancer is cancer that starts in the lungs. It is the leading cause of cancer death, but early detection and newer treatments are improving outcomes.
Symptoms
- A cough that does not go away or gets worse
- Coughing up blood
- Chest pain that worsens with breathing or coughing
- Shortness of breath
- Unexplained weight loss
Causes
Smoking is the leading cause. Other causes include secondhand smoke, radon, and workplace exposures. Some people with no risk factors still develop it.
Types
- Non-small cell lung cancer (most common)
- Small cell lung cancer (tends to grow faster)
Diagnosis
Diagnosed with imaging (such as a CT scan) and a biopsy. Low-dose CT screening is recommended for some current or former smokers.
Treatment
Depends on the type and stage and may include surgery, radiation, chemotherapy, targeted therapy, and immunotherapy. A team tailors the plan.
Living with it
- Quit smoking - it helps at any stage
- Follow your treatment and follow-up scan schedule
- Stay as active as your energy allows
- Eat well and manage breathlessness with pulmonary rehab if offered
- Ask about clinical trials
Complications
- Spread to other organs (metastasis)
- Fluid around the lung (pleural effusion)
- Breathing problems
- Blood clots
Frequently asked questions
Should I be screened for lung cancer?
If you are 50–80 with a heavy smoking history, ask your doctor about yearly low-dose CT screening. Screening finds cancer earlier when it is more treatable.
