Lung cancer

This information tells you about primary lung cancer (cancer that starts in the lungs), its causes and symptoms and what is likely to happen if you are diagnosed with this type of cancer.

Quick facts

  • Lung cancer is the second most common cancer in the UK, with more than 38,000 people diagnosed each year.
  • Smoking is the cause of most cases.
  • There are two main types of primary lung cancer, small cell lung cancer and non-small cell lung cancer. About 1 in 5 lung cancers are small cell; the rest are non-small cell.
  • The two main types are treated quite differently. Chemotherapy and radiotherapy are usually used for small cell lung cancer. Surgery, chemotherapy and radiotherapy can all be used for non-small cell lung cancer. 

We have information on other cancer types that affect the lungs:

  • Mesotheliomaopens the desktop site is a less common type of cancer that can affect the covering of the lungs. It often occurs in people who have been exposed to asbestos. 
  • Secondary cancer in the lungopens the desktop site describes the situation where cancer cells have spread to the lungs from a cancer that began elsewhere in the body.
  • There are other rarer types of cancer which can occur in the lungs. These include:
    • carcinosarcoma
    • pulmonary blastoma
    • malignant melanoma
    • malignant lymphoma
    • others.

We have more information on this topic on our desktop site.
