Lung Cancer; A Disease That Traps Both Smokers And Non-Smokers

How Far Has It Gone?

With the help of a combination of T, N, and M rates, doctors classify NSCLC into four stages:

1- The tumor hasn’t spread in different organs and lymph nodes and is in a single lung.

2- Cancer has grown and spread into the lymph nodes inside the lung; not in other organs.

3- Cancer has developed in lymph nodes at the center of the chest; not yet in distant organs.

3a- Cancer has not developed on the opposite side of the body.

3b- Cancer has grown in the lymph nodes in the opposite lung and has spread above the collarbone to the throat and neck.

4-  Cancer has spread throughout the body.
