Colorectal Cancer Screening

A colonoscopy can actually stop cancer. So what's stopping you?

Colorectal cancer is a leading cause of cancer death in the U.S. But a colonoscopy can actually prevent it. During the colonoscopy, your doctor can see and remove polyps, which can be the precursors to cancer. And it's really not as bad as you think - you can sleep right throught it. There are also other screening tests - learn more about these.

    "Because my dad had colon cancer, I had a colonoscopy twice before I was 50. It wasn't bad at all. And I feel so much better knowing I am healthy. I will have regular colonoscopies when it is time."

    -- C.H., Legacy patient

When to begin screenings

Most people should begin screening for colorectal cancer at age 50. African-Americans and those with a family history should start screening earlier. Learn more about screening recommendations.

If polyps are found

Polyps found during colonoscopy or sigmoidoscopy can usually be removed and sent for laboratory analysis to determine their type. Your recommended schedule of screenings will depend on the type, number and size of the polyps, your family history and any other risk factors.

If your screening does find cancer, please feel free to call our Oncology Nurse Navigators at 1-877-777-0112. They can answer your questions, help you find a cancer specialist, and guide you through your treatment.
