Lung Cancer

What is Lung Cancer?

Lung cancer refers to the uncontrolled growth of abnormal cells in the tissue of one or both lungs, which takes the form of a malignant tumour.1  The cancer can be found in the airway tubes (bronchus) or in the spongy lung tissue (alveoli). Lung tumours may also be caused by cancer which has spread from another part of the body but these are not considered as lung cancer per se.

There are two major types of lung cancer: 1

  • Non-small cell lung cancer (NSCLC) – the most common type of lung cancer
  • Small cell lung cancer (SCLC) – makes up 10-15% of all lung cancer cases and is the most aggressive lung cancer; occurs almost only in heavy smokers.

Lung cancer is the second and third most common cancer in males and females in Singapore respectively.1
