My doctor said I should get a colonoscopy, but I've heard that they aren't safe.

The American College of Gastroenterology recommends that people over 50 should have a screening colonoscopy every 10 years. However, if you have certain risk factors such as having inflammatory bowel disease or family history of cancer, your doctor may recommend more frequent screenings. You can discuss the pros and cons with your doctor to determine what is right for you.
