Rectal Cancer Causes, Symptoms, Diagnosis and Treatment

What Is Rectal Cancer?

Also known as colorectal or colon cancer, rectal cancer is the development of cancer in the colon or rectum, which are parts of the larger intestine.

It generally begins as a benign tumor, usually in the form of a polyp, which over the course of time becomes cancerous.

Rectal cancer may be diagnosed by obtaining a sample of the colon during a sigmoidoscopy or colonoscopy and may be treated differently as per different stages require. The earlier it is diagnosed, the earlier are the chances of survival.

Cancers that are confined within the wall of the colon may be curable with surgery while cancer that has spread widely is usually not curable.

Globally, it is the third most common type of cancer making up about 10% of all cases. It is more common in developed countries, where more than 65% of cases are found.
