How does Crohn's disease affect your cancer risk? | Nebraska Medicine Omaha, NE

What To Know

People with Crohn's disease can have a higher risk of colorectal cancer, especially when the colon is involved or when the disease has been present for many years.

This Nebraska Medicine article explains risk factors (like duration of disease, age, family history, smoking, obesity, and type 2 diabetes) and emphasizes regular colonoscopy screening — with a recommendation to consider colonoscopy every 1–2 years after roughly 8 years of disease — plus lifestyle steps such as quitting smoking, exercising, and eating anti-inflammatory foods.

The piece is educational and aimed at patients: it stresses early detection, monitoring symptoms (new or worsening blood in stool, worsening cramping, weight loss), and talking with your provider about individualized screening frequency.

It does not present new research findings or trial data; rather it summarizes standard prevention and surveillance practices for people with long-standing Crohn's disease. If you have ongoing symptoms or changes from your usual Crohn's pattern, the article advises contacting your clinician and staying up to date with colonoscopy screening.

It also suggests maintaining disease control as a way to lower cancer risk.
