Colorectal Cancer Screening
full-fill
What is colorectal cancer?
Colorectal cancer is a type of cancer that starts in the colon or rectum, which are parts of the digestive system. It often begins as small growths called polyps on the inner lining of the colon or rectum. While most polyps are harmless, some can develop into cancer over time.
This year, more than 50,000 people in the U.S. will lose their lives to colorectal cancer. Many of these lives could have been saved. If colorectal cancer is found early, 9 out of 10 people survive.
The American Cancer Society recommends that people at average risk start regular colorectal cancer screening at age 45.

How to check for colorectal cancer
Screening helps catch colorectal cancer early, when it’s easiest to treat. Here are two common ways to get checked:
- Colonoscopy: A doctor uses a tiny camera to look inside your colon to check for problems. Learn more below.
- Stool tests: These tests check your stool for hidden blood or changes in DNA. Learn more below.
Most people should start screening at age 45. If you have a higher risk, you may need to start sooner or get tested more often. Talk to your provider today.

What is a colonoscopy?
A colonoscopy is a test that lets a doctor look inside your colon.
The tube is gently put into your rectum and moved through your colon to where it starts. The colonoscope has a small camera and a light on it. This lets the doctor see if there are any problems inside.
It might sound a bit scary, but it’s not. You will get medicine before the procedure to help you sleep, so you won’t feel anything.
This test can save your life by finding issues early.
What is a stool test?
A stool test is a simple way to check for signs of colorectal cancer. You can usually do these tests at home with a kit your doctor gives you. If the test finds something unusual, your doctor may recommend a colonoscopy to learn more.
There are different types of stool tests:
- FIT (fecal immunochemical test): This test looks for blood in your stool that you can’t see.
- FIT-DNA Test: This test checks for both hidden blood and changes in your stool’s DNA.
