Colon Cancer Screening

Why should I get screened for colon cancer?

Colon cancer, also called colorectal cancer, is a growth of abnormal cells in a person’s colon.  Colon cancer screening detects any abnormal growths, called polyps, in the colon. If these growths are found early, they can often be treated before they become cancerous.

Colon cancer is usually preventable with regular screening. Screening also reduces a person’s risk of dying from colorectal cancer by 60 percent.

This type of cancer affects men and women equally, and nearly one in every 20 people will be diagnosed with colorectal cancer. We recommend that every person over the age of 45 get screened. How often you need to get screened depends on the type of testing you choose to do. 

If you have a family history of colorectal cancer, irritable bowel disease or other cancers, you may want to get screened at a younger age. Speak to your primary care doctor to find out when and how often you should get a screening.

Where can I get screened?

Denver Health offers colorectal cancer screening at our Gastroenterology Lab on the Denver Health main campus, located in downtown Denver. We recommend speaking to your primary care doctor about screening first. Your doctor can then refer you to our clinic for the appropriate testing.
