Colon Cancer Screening Trends for Ages 45-49
Recent findings from the American Cancer Society indicate that more individuals aged 45 to 49 are undergoing screenings for colon cancer, resulting in increased early-stage diagnoses.
The research, published in two studies in the Journal of the American Medical Association, highlights that a rise in screenings for those under 50 correlates with more cases being diagnosed early. One study noted that the annual diagnosis rate of colorectal cancer among 45 to 49-year-olds increased from 1.1% from 2004 to 2019 to 12% from 2019 to 2022. Another study reported a 62% increase in screenings among U.S. adults in that age group from 2019 to 2023.
The American Cancer Society and the U.S. Preventive Services Task Force revised their guidelines, recommending that colorectal screenings begin at age 45 instead of 50. This shift occurred in 2018 and 2021, respectively.
In a news release, Elizabeth Schafer, the lead author and a health equity scientist, referred to the findings as “promising news.” She suggested that the rise in cases likely results from first-time screenings following these new guidelines.
Jessica Star, another lead author focused on cancer risk factors and surveillance, expressed enthusiasm regarding the uptick in screenings, which may be influencing more early diagnoses. However, she also cautioned that there remains significant work ahead. She pointed out that screening rates among those aged 45 to 49 are still not optimal and vary based on education and insurance status.
Concerns have been raised by medical associations regarding a potential report suggesting that Health and Human Services Secretary Robert F. Kennedy may consider removing all members from the U.S. Preventive Services Task Force. This group of independent medical experts plays a role in shaping recommendations for preventive health measures, including cancer screenings.
Dr. Thomas Lew, an assistant clinical professor at the Stanford University School of Medicine, remarked that such a change could be detrimental, undermining efforts in preventive care and potentially increasing health costs. He described the situation as “extremely concerning,” suggesting it would counter efforts to improve public health.
An HHS spokesperson clarified that no final decision had been made regarding how the USPSTF could enhance its support for HHS’ goal of improving health in America.
