At what age is colorectal cancer screening generally recommended to begin?

Colorectal cancer screening is generally recommended to begin at age 45. This guideline was updated based on increasing incidence rates of colorectal cancer in younger populations. Evidence suggests that beginning screening at 45 allows for earlier detection of potential malignancies, which can lead to better outcomes. The recommendations aim to catch diseases at an earlier, more treatable stage, especially since colorectal cancer can develop with few or no symptoms in its initial stages.

While other ages may have been considered in the past, recent updates from organizations such as the American Cancer Society now endorse the 45-year mark as the standard for average-risk individuals. This change reflects a proactive approach to address the rising trends in colorectal cancer among younger adults.
