At what age does colorectal screening ideally begin for individuals without risk factors?

Colorectal cancer screening is an essential public health measure aimed at reducing mortality through early detection and prevention. For individuals without particular risk factors, guidelines recommend that screening for colorectal cancer should ideally begin at age 45. Recent updates in recommendations, especially from organizations like the American Cancer Society, have highlighted that starting screening earlier than the traditional age of 50 may help identify cancers at a stage when they are more treatable and address increasing incidence rates in younger populations.

That said, while the choice of 50 is often associated with earlier guidelines, the updated recommendation reflects a change in understanding of the disease's epidemiology, pushing for initiation at 45 for average-risk individuals. The recommendation aims to balance benefits of early detection with potential risks and harms associated with screening in younger individuals.

Therefore, while the choice of 50 reflects past practices, the current best practices endorse starting at 45, making this the correct age for initiating colorectal cancer screenings in individuals without risk factors.
