Medical Crisis: Rectal Cancer Spikes in Young People
23 Apr
Summary
- Rectal cancer deaths are rising rapidly among millennials.
- Rectal cancer deaths could surpass colon cancer deaths by 2035.
- Hispanic adults show the steepest rise in rectal cancer mortality.

Deaths from rectal cancer are rapidly increasing among younger adults, a concerning trend that scientists are actively investigating. This surge is particularly pronounced in millennials, with research indicating that rectal cancer deaths are rising at a rate up to three times faster than colon cancer deaths.
If current trends persist, rectal cancer fatalities are projected to exceed those of colon cancer by 2035. In 2026, an estimated 158,850 new colorectal cancers are expected to be diagnosed, with nearly a third of deaths occurring in individuals under age 65. Hispanic adults are experiencing the most significant increase in rectal cancer mortality.
Scientists are seeking to understand the underlying causes of this rise, exploring potential factors such as disruptions in the gut microbiome or environmental exposures from decades past. Standard treatments for rectal cancer include surgery, radiation, and chemotherapy, which can have significant side effects.
Early detection is crucial, as colorectal cancer is curable when found early. However, a substantial number of younger patients are diagnosed at advanced stages, contributing to rising mortality rates. Experts emphasize the importance of seeking medical attention for any changes in bowel function.
