Rising Rectal Cancer Rates in Younger Americans
Recent research reveals a concerning trend: rectal cancer deaths are increasing at a much higher rate than colon cancer deaths among younger Americans. Experts fear this trend will continue unless treatment approaches are changed.
According to a study that will be presented at Digestive Disease Week 2026 in Chicago, mortality rates for rectal cancer are climbing two to three times faster than those for colon cancer in individuals aged 20 to 44. The findings suggest that for older millennials—those between 35 to 44 years old—death rates from rectal cancer could continue to rise through 2035.
“Colorectal cancer is increasingly affecting younger individuals,” said Mythili Menon Pathiyil, the lead author of the study and a gastroenterology fellow at SUNY Upstate Medical University. “Rectal cancer, in particular, is becoming a major concern for this age group.”
The study analyzed death records from the Centers for Disease Control and Prevention (CDC) spanning from 1999 to 2023. It found that Hispanic adults and those living in the Western United States have experienced the sharpest rises in rectal cancer deaths.
Using advanced data analysis techniques, researchers discovered that the gap in mortality rates between rectal and colon cancer is expanding across various demographic groups. A significant issue highlighted by the research is the delay in diagnosis for younger patients.
Dr. Rachel Gordon, a colorectal and general surgeon, noted, “We are seeing younger people diagnosed with rectal cancer at much earlier ages, often in more advanced and aggressive stages.” She pointed out that while older adults usually start treatment within a month of noticing symptoms, young adults can wait an average of seven months before receiving care.
Experts suggest that lifestyle factors, environmental influences, and dietary changes may be behind this troubling trend. Unfortunately, primary care doctors often overlook serious symptoms like rectal bleeding or changes in bowel habits, mistakenly attributing them to less serious issues like hemorrhoids.
Pathiyil emphasized the importance of taking symptoms seriously. “If something feels off or if you notice symptoms like rectal bleeding, persistent changes in bowel habits, or unexplained weight loss, seeking prompt medical attention is crucial,” she advised.
The findings indicate that current screening methods may need a re-evaluation to address this growing health concern. As Pathiyil concluded, “Rectal cancer is a driving force behind the increasing rates of colorectal cancers, and action is essential to prevent further escalation of this issue.”
