Lung cancer

Rich Text 1

The lungs are two organs that are part of the respiratory system and help us to breathe.

Primary lung cancer starts in the lung. Secondary lung cancer occurs when cancer starts in another part of the body and spreads (metastasises) to the lung.


Types of lung cancer

There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer.


Non-small cell lung cancer

This is the most common type of lung cancer, accounting for about 85% of cases.

There are different subtypes of non-small cell lung cancer, including:

  • Adenocarcinoma
  • Squamous cell (epidermoid) carcinoma
  • Large cell undifferentiated carcinoma


Small cell lung cancer

This type of lung cancer usually starts in the middle of the lungs, and often spreads more quickly than non-small cell lung cancer.
