Overview

Colorectal 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 cancer-related death in the Western world. Colorectal cancer causes 655,000 deaths worldwide per year.[1] In 2009, there were 51,000 deaths from colorectal cancer as well as 103,000 new cases of colon cancer and 40,000 cases of rectal in the United States.

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 should they acquire a sequence of DNA damaging events.[2]

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

Therapy is usually through surgery, which in many cases is followed by chemotherapy.

Treatment

The treatment depends on the staging of the cancer. When colorectal cancer is caught at early stages (with little spread) it can be curable. However when it is detected at later stages (when distant metastases are present) it is less likely to be curable.
