At what age is it recommended to start screening for colon cancer?

Screening for colon cancer is recommended to begin at age 45 for average-risk individuals. This recommendation aligns with guidelines from organizations such as the American Cancer Society and the U.S. Preventive Services Task Force. The rationale behind starting at this age is based on research indicating that the incidence of colorectal cancer is increasing among younger populations, leading to a shift in guidelines to initiate screening earlier than the traditional age of 50.

By beginning screenings at age 45, there is a better chance of detecting cancer in its early stages, which can significantly improve treatment outcomes and reduce the risk of more advanced disease. Early detection through screening can lead to the identification and removal of precancerous polyps, further decreasing the risk of developing colon cancer.

This age also balances the need for timely detection with the practicality of ensuring that more individuals are screened as they approach and enter their middle ages when the risk of colorectal cancer increases.
