Lung Cancer: Basic Facts

21 Oct 2013

What is lung cancer? Lung cancer is the uncontrolled growth of abnormal cells that start off in one or both lungs; usually in the cells that line the air passages and lungs. It is common in Malaysia and is a leading cause of cancer in the whole world. Globally, amongst all cancers, it is the number one killer in men and women. Primary lung cancer originates in the lungs, while secondary lung cancer starts somewhere else in the body and then spreads (metastasizes) to the lungs. Lung cancer can be classified into two main types based on the cancer’s appearance under a microscope:

  • Small cell lung carcinoma (SCLC) -20%
  • Non-small cell lung carcinoma (NSCLC) – 80%
