Only you can make the decision to get a colonoscopy. It’s generally a safe procedure, and it’s a popular option for colorectal cancer screening because your doctor can both find and remove polyps in one session.

Stool tests or a blood test are also an option if you’re not ready for a colonoscopy. But you need to get your screening done and repeat it regularly. Non-invasive tests must be done every 1 to 3 years, depending on the type of test. If your test results are abnormal, a follow-up colonoscopy will be needed.

The greatest risk is not getting screened at all.
