Colorectal Screening at 45: CT Colonography and Traditional Approaches

Screening for colorectal health starts earlier than many people expect. In North America, guidelines now commonly recommend beginning routine screening at age 45 for average-risk individuals, with options that fit different needs and tolerances. A virtual colonoscopy, also known as CT colonography, is one such option. It uses computed tomography to create detailed images of the colon and rectum, helping doctors detect polyps or signs of cancer without the need for a traditional scope during the initial test. This approach is especially relevant for people who prefer a less invasive experience or who may be at higher risk for complications from conventional colonoscopy. Contemporary oncology discussions often include this method as part of a broader, patient-centered screening plan. (American Cancer Society)
