When does colorectal cancer screening typically start?

Colorectal cancer screening typically starts at age 45 for average-risk individuals, which reflects recent updates in guidelines from organizations such as the American Cancer Society. This change was made to address the increasing incidence of colorectal cancer in younger populations.

Screenings can include methods such as colonoscopy, fecal immunochemical tests, and other strategies, with the goal of early detection and prevention. Starting screening at age 45 allows for timely identification and management of any potential abnormalities before they progress to more advanced disease stages.

While some guidelines previously recommended beginning screening at age 50, the shift to starting at 45 allows healthcare providers to address the rising trends in colorectal cancer more effectively.
