What is colon cancer?

Colorectal cancer is also known as bowel cancer, colon cancer, or rectal cancer. Colorectal cancer begins as an abnormal growth of cells in the inner lining of the colon or rectum. This abnormal growth is called a polyp.

Some types of polyps can change into cancer over the course of several years. But it does not mean that all polyps have the tendency to become cancerous. The chance of changing a polyp into colorectal cancer depends on the type of polyp that grows. 

Colorectal cancer can affect men and women equally. However, studies have proven that men might develop it at a younger age.
