What is Lung Cancer?

A cancer that begins in the lungs and most often occurs in people who smoke.
Two major types of lung cancer are non-small cell lung cancer and small cell lung cancer. Causes of lung cancer include smoking, second-hand smoke, exposure to certain toxins and family history.
Symptoms include a cough (often with blood), chest pain, wheezing and weight loss. These symptoms often don’t appear until the cancer is advanced.
Treatments vary but may include surgery, chemotherapy, radiation therapy, targeted drug therapy and immunotherapy.

Symptoms

Lung cancer typically doesn’t cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur when the disease is advanced.

Signs and symptoms of lung cancer may include:

  • A new cough that doesn’t go away
  • Coughing up blood, even a small amount
  • Shortness of breath
  • Chest pain
  • Hoarseness
  • Losing weight without trying
  • Bone pain
  • Headache
