Rising Rectal Cancer Rates Among Young Americans

Recent research indicates that deaths from rectal cancer in younger individuals are on the rise at a significantly faster pace than those from colon cancer in the United States. Experts express concern that unless there are changes in treatment protocols, this trend is likely to continue.

Specifically, mortality rates for rectal cancer among adults aged 20 to 44 are climbing two to three times faster than those for colon cancer. This data will be presented at Digestive Disease Week 2026 in Chicago, suggesting that older millennials, particularly those between 35 and 44, may see a continued increase in mortality rates through 2035.

Mythili Menon Patiyil, a gastroenterology researcher from New York State Upstate Medical University, emphasized that “colorectal cancer is no longer regarded solely as an issue for the elderly.” She identified rectal cancer as a significant concern for younger populations.

Researchers analyzed death records from the Centers for Disease Control and Prevention covering the years from 1999 to 2023.

The study found that Hispanic adults and those residing in western states experienced the steepest increases in rectal cancer fatalities. Age and cultural factors could be influencing these trends.

A primary issue highlighted by the research is the delayed diagnoses that younger patients often face. Dr. Rachel Gordon, a colorectal and general surgeon, noted that young individuals are increasingly being diagnosed with rectal cancer at younger ages and typically at more advanced stages of the disease.

Interestingly, while older patients usually begin treatment within a month of experiencing symptoms, younger patients wait an average of seven months before seeking help. This delay can be critical, as early intervention is key to better outcomes.

Patiyil pointed out that primary care providers may dismiss warning signs in younger people—like rectal bleeding or altered bowel habits—considering them benign issues such as hemorrhoids.

Experts stress the importance of recognizing symptoms, which may include rectal bleeding, ongoing changes in bowel habits, and unexpected weight loss. Gordon urged anyone feeling unusual symptoms to consult their doctor promptly.

The findings from this study imply a need to reassess current screening practices for colorectal cancer. Patiyil concluded, “Our study suggests that rectal cancer significantly contributes to the overall rise in colorectal cancer cases. If we don’t adapt our approach now, the situation may worsen over time.”
