Description of the stages involved in the development and spread of lung cancer

The attack and spread of lung cancer occur through four main stages. The disease advances from one stage to another.

Stage 1

The cancer cells are first located in the lung cells and do not show any sign of spread to other parts of the body or to any lymph nodes (Detterbeck, 2001). 

Stage 2

The cancer cells are spread in many parts of the lungs and the few available lymph nodes.

Stage 3

 The cancer cells spread to various parts of the lungs and in the lymph nodes located in the middle part of the chest.  The third stage is marked by two subtypes.

Stage 3A is marked when the cancer cells have spread only to the lymph nodes on the same side of the chest in which cancer first started.  Stage 3B is marked when the cancer cells have spread to the lymph nodes located on the opposite side of the chest or the region located above the collar bone (Simmers, et.al, 2009).

Stage 4

The advanced stage of lung cancer is marked at this stage. In this stage, cancer has spread to both lungs and any other part of body organs such as the liver.
