\nThe United States Preventive Services Task Force (USPSTF) recommends that men and women who are 50 to 75 years old should be screened for colorectal cancer in one of the following three ways\u2014
\nA newer test that can be used for colorectal cancer screening is computed tomographic (CT) colonography, also called virtual colonoscopy. CT colonography is an X-ray test that uses CT scanning and computer software to make images of the colon and rectum, like a colonoscopy. Although the USPSTF doesn\u2019t recommend CT colonography, other organizations recommend it every five years as a colorectal cancer screening option.
\nUsing data from the National Health Interview Survey, the study found the following rates of colorectal cancer screening test use in 2010\u2014
\nPeople were more likely to be screened for colorectal cancer if they\u2014
\nPeople were less likely to be screened if they\u2014
\nAbout 40% of people in the United States who are 50 to 75 years old have not been screened for colorectal cancer as recommended. People who do not have health insurance or a usual source of health care were the least likely to be screened. Also, many people don\u2019t know they need to be screened for colorectal cancer.
