Purpose Of Review:
The colonoscopy guidelines recently changed to begin screening at age 45. This review discusses the reasons for lowering the age, adenomatous polyp detection rates for patients 45-49, and to discover innovative health education campaigns aimed at younger patients.
Recent Findings:
There are currently approximately 20 million Americans between the age of 45-49 who will need to be screened by gastroenterologists. The prevalence of overall and advanced colorectal neoplasia on screening colonoscopy for average-risk individuals younger than 50 years is 14% and 2%. An important 2022 study using the GI Quality Improvement Consortium Registry demonstrated that patients aged 45-49 had an overall adenoma detection rate of >25%.
Summary:
Health education campaigns need to immediately target 20 million Americans to begin colorectal cancer screening. Additional research should focus on whether there are sex differences for adenoma detection rates among patients aged 46-49. Innovative health education campaigns such as "Tune It Up: A Concert To Raise Colorectal Cancer" organized by the American College of Gastroenterology are educating younger patients to begin colorectal screening by combining concerts and health communication.
