What Should I Know About Screening for Colorectal Cancer

What Is Colorectal Cancer Screening?

First and foremost you should be able to answer the question “what is colorectal cancer screening’? The purpose of a screening test is to look for diseases when there are no visible signs or symptoms of it. It’s different from the diagnostic test which is done to find out the cause of visible symptoms [1].

Colorectal Cancer is an abnormal growth in the abdomen (colon or rectum) that is as a result of mutation of cells. The disease at initial stages when the precancerous polyps is developing may not show any signs or symptoms. Screening tests can find precancerous polyps, so that they can be removed before they turn into cancer. Screening tests can also find colorectal cancer early, when treatment works best.
