It used to be considered an older person’s disease. But colorectal cancer is showing up more and more in people under 50—and the numbers are alarming.
The Numbers Don’t Lie
Colorectal cancer is now the leading cause of cancer death in men under 50, and second in women under 50. Rates have been rising steadily in young adults since the 1990s.
According to the American Cancer Society, adults born in the 1990s have double the risk of colon cancer and quadruple the risk of rectal cancer compared to those born in the 1950s.
Why the Rise?
The exact reasons aren’t fully clear, but likely contributors include:
- Poor diet high in processed food and red meat
- Sedentary lifestyles
- Obesity and metabolic syndrome
- Gut microbiome changes
- Chronic inflammation
Genetics still play a role—but environment and lifestyle seem to be accelerating things.
Symptoms to Watch (Even If You’re Young)
- Rectal bleeding or blood in stool
- Unexplained weight loss
- Persistent constipation or diarrhea
- Abdominal pain or cramping
- Fatigue or iron-deficiency anemia
Many young adults brush off symptoms or get misdiagnosed because cancer “isn’t supposed to happen” at that age. That delay can be deadly.
Screening and Prevention
The USPSTF now recommends starting colorectal cancer screening at age 45—earlier if you have a family history or risk factors. Colonoscopy remains the gold standard, but stool-based tests are also effective.
To reduce your risk:
- Eat more fiber (fruits, veggies, whole grains)
- Cut back on processed and red meats
- Move more—regular exercise helps
- Limit alcohol and avoid smoking
Don’t Wait to Speak Up
If something feels off, push for answers. Early-onset colorectal cancer is often more aggressive, but it’s also highly treatable when caught early.
