Men at average risk should begin getting a colonoscopy at age 45, according to current guidelines from major health organizations like the American Cancer Society and the U.S. Preventive Services Task Force. This age reflects updated recommendations that aim to catch colorectal cancer earlier than prior guidelines, which suggested starting at age 50. Men at increased risk due to family history, personal history of polyps, inflammatory bowel disease, or other factors may need to start screening earlier and have more frequent exams. Regular screening through colonoscopy helps detect and remove precancerous polyps and can identify other colon conditions, significantly reducing the risk of developing advanced colorectal cancer. Screening is generally recommended through age 75, with individualized decisions for ages 76 to 85 based on overall health and prior screening. Screening is typically not recommended after 85. In summary:
- Begin colonoscopy screening at age 45 for average-risk men.
- Start earlier if there are personal or family risk factors.
- Continue regular screenings through age 75, with personalized decisions thereafter.
These recommendations emphasize early detection and prevention to improve outcomes and reduce colon cancer deaths.
