What is a polyp in colorectal cancer?

A polyp is a growth inside the colon or rectum. Colorectal cancer often begins as one of these growths.

This connection matters. Because colorectal cancer often starts as a polyp, finding and removing polyps can prevent colorectal cancer. If a polyp is found and removed before it becomes cancer, that step can stop the cancer from forming.

This is one reason screening is helpful. Screening tests can be used to detect colorectal cancer and polyps, sometimes before any symptoms appear. Your healthcare team can explain which screening options may be right for you, when to have them, and what happens if a polyp is found.
