Rectal Cancer Deaths Accelerating Among Older Millennials, Outpacing Colon Cancer

New research to be presented at Digestive Disease Week 2026 reveals that rectal cancer mortality rates among older millennials are rising faster than colon cancer deaths in the same demographic group. The findings indicate that rectal cancer is striking younger patients earlier in life and progressing more rapidly to fatal outcomes. Medical experts are calling for primary care doctors to thoroughly investigate early gastrointestinal symptoms in patients under age 45 rather than dismissing them. The accelerating death rates suggest current screening protocols may need revision to catch rectal cancer earlier in millennial populations.

Rising rectal cancer mortality among older millennials

• ▪Rectal cancer deaths among older millennials are accelerating.
• ▪Growth in rectal cancer mortality among older millennials is far outpacing colon cancer mortality growth.

Clinical implications for early screening and diagnosis

• ▪A study on rectal cancer deaths among older millennials will be presented at Digestive Disease Week 2026.
• ▪Primary care doctors should fully investigate early symptoms in patients under age 45 for rectal cancer.

Perspective of Primary care doctors

• ▪Primary care doctors should not dismiss gastrointestinal symptoms in patients under 45 as benign conditions.
• ▪Primary care physicians need to maintain higher clinical suspicion for rectal cancer in millennial patients than previously standard.

Perspective of Screening guideline organizations

• ▪Current colorectal cancer screening age guidelines may be inadequate given accelerating rectal cancer deaths in older millennials.
• ▪Earlier colorectal cancer screening initiation for patients under 45 may be warranted due to rising rectal cancer mortality trends.
