What is colorectal cancer?



The colon denotes commonly the last 6 feet (1.80 meters) of the intestines leading to the small intestine to the rectum. The colon is also known as large intestine. The last part of the large intestine is the rectum.

Colon cancer or colorectal cancer (terms used interchangeably) is a cancer of cells lining the colon. Almost all colorectal cancer cases are caused by the growth of benign polyps (noncancerous). These polyps can become cancerous and invade the colon wall and surrounding blood vessels and spread to other body parts. The symptoms are virtually unnoticed in the initial phases, while the condition is easier to treat, this is why regular screening examinations are important.
