At what age is colorectal cancer screening recommended to begin?
45 years old
50 years old
55 years old
60 years old
The correct answer is: 50 years old
Colorectal cancer screening is recommended to begin at 45 years old for average-risk individuals, as updated guidelines from the American Cancer Society and other leading health organizations indicate a shift in the screening age due to the increasing incidence of colorectal cancer among younger adults. Starting screening at 50 years was traditionally believed to be appropriate; however, this recommendation has been adjusted as evidence shows that the risk of colorectal cancer increases at an earlier age. Therefore, the correct guideline now advocates initiating screening at 45 years, making the accurate recommendation essential for early detection and improved outcomes in colorectal cancer. The earlier recommendations of starting at ages 50 or older do not reflect current evidence, which demonstrates that screening younger individuals can aid in catching cancers in their earlier stages when treatment is more effective.
