A study published in the journal JAMA Network Open found that there was a significant increase in colorectal cancer screenings among younger people after the recommended screening age was lowered to 45 in 2021 by the U.S. Preventive Services Task Force. This change was made in response to the rising cases of colorectal cancer in people younger than 50 over the last two decades. The study, which analyzed data from over 10 million people with Blue Cross Blue Shield insurance, showed that screening rates among people ages 45 to 49 tripled following the guideline change.
The increase in screening was seen mostly in people living in wealthier areas, indicating disparities in access to screening services. Early-onset colorectal cancer is a significant concern, as about 11% of cases are diagnosed in people under 50. The study results were deemed promising by experts, but they noted that those without insurance likely have lower screening rates. Noninvasive screening methods, like the stool test Cologuard and the blood test Shield, are becoming more popular and contribute to the increase in screenings among the insured population.
While colonoscopy remains the gold standard for colorectal cancer screening, less invasive methods are essential for increasing screening rates. However, for individuals with a history of colon cancer or a strong family history, colonoscopy is still necessary. Overall, the study highlights the importance of awareness around the new recommended screening age and the need to ensure access to screening services for all individuals, regardless of socioeconomic status.
