OVERVIEW

Lung cancer is the abnormal growth of malignant cells in lung tissue. The lungs reside in the chest cavity and allow oxygen to be transported into the bloodstream.

There are two main types of lung cancer:

  • small cell lung cancer; and
  • non-small cell lung cancer.

 

Small cell lung cancer (SCLC)

SCLC is a fast-growing and aggressive cancer that spreads quickly. SCLC is slightly more common in men than women, and most cases are caused by smoking cigarettes.

Non-small cell lung cancer (NSCLC)

NSCLC is the most common type of lung cancer and it spreads more slowly than SCLC. NSCLC can be caused by air pollutants, smoking and drinking water with high levels of arsenic.

Smoking cigarettes is the leading cause of lung cancer.
