Increased Colorectal Cancer Rates among Adults under Fifty Are Causally Linked to Increased Screening

[BootinUp]

Excerpt

In 2021, the U.S. Preventive Services Task Force dropped the age for colonoscopy screening from fifty to forty-five, which means colorectal cancer cases in adults under fifty will now be captured through routine screening.

The first noninvasive DNA-based test for colon cancer, Cologuard, was approved in 2014 and expanded to adults forty-five to forty-nine in 2019, increasing the pool of under-fifty adults getting screened for colorectal cancers. And indeed, the data demonstrate that the headlines sounding the alarm about increased colorectal cancer in adults under fifty are causally linked to these changes in screening recommendations. When screening expands, detection increases.

Modifiable risk factors associated with early-onset cancers remain unchanged: diets low in fiber and high in animal fats, excess alcohol consumption, tobacco and non-tobacco smoking products, and a sedentary lifestyle. The fundamentals for overall health do not involve wellness industry supplement concoctions or “hacking” your metabolism.
