Colon cancer is no longer just an “older person” disease—rates are rising in people in their 20s, 30s and 40s.
Colon cancer is hitting young adults. Here’s why.
More young people are being diagnosed, and there isn’t one single cause. It’s a perfect storm of:
Modern diet: Lots of ultra-processed foods, red/processed meats and sugary drinks, not enough fiber
Weight & inactivity: More obesity and sedentary lifestyles
Gut & environment: Changes in gut bacteria, early-life antibiotics, and exposure to chemicals and pollutants
Genes & family history: Hereditary syndromes, polyps, and inflammatory bowel disease can drive risk at younger ages
Each newer generation seems to carry higher risk earlier in life, likely from exposures starting in childhood.
Protect yourself:
- Eat more plants and fiber,less ultra-processed and processed meat
- Move your body most days and maintain a healthy weight
- Avoid smoking and heavy alcohol
- Know your family history
- Never ignore blood in stool, bowel changes, unexplained weight loss, or ongoing abdominal pain
- Ask a GI specialist when YOU should start screening—many need it before 45
