Learn about colorectal cancer screening tests and at what age you should start them. Find out if you might be at high risk and may need a colonoscopy sooner.
Screen all adults aged 45 to 75 years for colorectal cancer. Several recommended screening tests are available. Clinicians and patients may consider a variety of factors in deciding which test may be best for each person.
Screening recommendations. The US Preventive Services Task Force (Task Force) recommends that adults age 45 to 75 be screened for colorectal cancer. The decision to be screened between ages 76 and 85 should be made on an individual basis. If you are older than 75, talk to your doctor about screening.
Two-step screening methods consist of a screening modality followed by a colonoscopy for a positive test. Flexible sigmoidoscopy enables diagnostic polyp removal up to the distal colon but ...
Age to Initiate Screening - We suggest starting CRC screening at age 45 in average risk individuals and using either colonoscopy or fecal immunochemical test (FIT) as the primary screening modality. Other screening options include multitarget stool DNA test, CT colonography, and colon capsule.
About 7 in 10 US adults aged 50 to 75 are up to date with colorectal cancer screening. Colorectal cancer screening saves lives. Screening can find precancerous polyps—abnormal growths in the colon or rectum—that can be removed before they turn into cancer. Screening also helps find colorectal cancer at an early stage, when treatment works best.
The American Cancer Society 2018 guideline for colorectal cancer screening recommends that average-risk adults aged 45 years and older undergo regular screening with either a high-sensitivity stool-based test or a structural (visual) exam, based on personal preferences and test availability.
The USPSTF continues to recommend selectively screening adults aged 76 to 85 years for colorectal cancer. How to implement this recommendation? Screen all adults aged 45 to 75 years for colorectal cancer. Several recommended screening tests are available.
Screening with any one of multiple options is associated with a significant reduction in CRC incidence through the detection and removal of adenomatous polyps and other precancerous lesions and with a reduction in mortality through incidence reduction and early detection of CRC.
Experts recommend screening colonoscopy every 10 years for people at average risk. Virtual colonoscopy, also called computed tomographic (CT) colonography, is a screening method that uses special x-ray equipment (a CT scanner) to produce a series of pictures of the colon and the rectum from outside the body. A computer then assembles these ...
