According to the fact sheet from World Health Organization, “Cancer” is a leading cause of death worldwide. The most common causes of cancer death are cancers of Lung (1.69 million deaths in 2015)

Lung cancer is the uncontrolled growth of abnormal cells in lungs. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, and can spread to other parts of the body. Risk of developing cancer depends on the type of lung cancer.

There are two major types of lung cancer, Small Cell Lung Cancer (SCLC) and Non-Small Cell Lung Cancer (NSCLC).

  • NSCLC is the most common type of lung cancer, making up 85-90% of all cases. It typically grows and spreads more slowly than SCLC.
  • SCLC comprises about 10%-15% of lung cancers. This type of lung cancer is the most aggressive and rapidly growing.
