When diagnosed early, colon cancer is more than 90% curable. For men with an average risk of colon cancer, colorectal screenings should start at 45 — now earlier than the previously recommended age of 50.
A gastroenterologist may perform colorectal cancer screening tests, including yearly stool-based tests, flexible sigmoidoscopy every five years, and colonoscopies every 10 years.
Your doctor may recommend more frequent screenings if you have a family history of colorectal cancer or polyps, or have certain conditions, including Crohn’s disease or ulcerative colitis.
