Recommended every 5 years for persons aged 50 years or older, sigmoidoscopy and colonoscopy are used as screening tools both for preventing cancer by detecting precancerous polyps and for detecting colorectal cancer early, when treatment is most effective. Studies have found that people who had had a sigmoidoscopy had 59% fewer deaths from colorectal cancers within reach of a sigmoidscope than people who had not had a sigmoidoscopy. Despite its proven effectiveness, colorectal cancer screening is used far less than screening for other cancers.
