Colorectal Cancer Screening Age Lowered: What Younger Adults Should Know

Following updated guidelines from the U.S. Preventive Services Task Force that lowered the recommended colorectal cancer screening age from 50 to 45, gastroenterologists across Palm Beach County are seeing a surge in screening colonoscopies among younger adults. The change reflects alarming trends in colorectal cancer incidence among adults under 50, which has increased by approximately 2 percent per year over the past two decades.

"We're diagnosing colon cancer in 40-year-olds at a rate that would have been unusual 20 years ago," said Dr. Richard Goldstein, a gastroenterologist at Boca Raton Regional Hospital. "The guideline change is an important step, but awareness among younger adults remains too low. Many in their 40s don't realize they should be getting screened."

Screening Options

While colonoscopy remains the gold standard for colorectal cancer screening, several non-invasive alternatives are available for those who are hesitant about the procedure. Stool-based tests, including the fecal immunochemical test (FIT) and Cologuard, can detect signs of cancer without sedation or bowel preparation, though positive results require follow-up colonoscopy.

For patients who choose colonoscopy, the procedure has become significantly more comfortable. Modern sedation techniques allow most patients to sleep through the entire examination, and the bowel preparation process has been improved with lower-volume, better-tasting solutions.

Insurance Coverage

Under the Affordable Care Act, screening colonoscopies are covered as preventive services with no out-of-pocket cost for most insured individuals. This coverage now extends to adults beginning at age 45. However, if the screening colonoscopy results in polyp removal, some plans may reclassify the procedure as diagnostic, potentially triggering cost-sharing.

The American Cancer Society estimates that colorectal cancer is the third most common cancer diagnosed in the United States and the second leading cause of cancer death, making screening one of the most impactful preventive health measures available.
