Colorectal cancer

Colorectal cancer, also called colon cancer or bowel cancer, includes cancerous growths in the colon, rectum and appendix.

It is the third most common form of cancer and the second leading cause of death among cancers in the Western world.

Many colorectal cancers are thought to arise from adenomatous polyps in the colon.

These mushroom-like growths are usually benign, but some may develop into cancer over time.

The majority of the time, the diagnosis of localized colon cancer is through colonoscopy.
