There are clear signs that colorectal cancer rates are rising among younger adults, and clinicians are warning people to pay attention to symptoms and risk factors.
What clinicians are seeing
Younger patients—some in their 30s and 40s—are increasingly being diagnosed with colorectal cancer. High-profile deaths among people under 50 have drawn attention to the trend and prompted calls to rethink how and when clinicians look for disease outside traditional screening ages.
Who is at higher risk
- People with a family history of colorectal cancer or certain inherited syndromes.
- Individuals with inflammatory bowel disease such as Crohn’s disease or ulcerative colitis.
- Those with lifestyle-related risks, including obesity, poor diet, heavy alcohol use, and physical inactivity.
- People who have concerning symptoms that persist, regardless of age.
Symptoms to watch for
- Persistent change in bowel habits (diarrhoea or constipation).
- Blood in the stool or rectal bleeding.
- Unexplained weight loss, ongoing abdominal pain, or a sense of incomplete bowel emptying.
What patients should do now
- Get evaluated promptly if you have persistent gastrointestinal symptoms. Primary care clinicians can arrange noninvasive tests and urgent referrals.
- Tell clinicians about family history and any prior gastrointestinal conditions.
- Discuss earlier screening if you have risk factors; options include stool-based tests and colonoscopy.
Early detection materially improves treatment options and outcomes. With an estimated surge in colorectal diagnoses this year and more disease appearing in younger people, health systems and clinicians are under pressure to raise awareness, lower barriers to diagnostic testing, and reconsider screening strategies for at-risk groups.
