What percentage of ulcerative colitis patients get cancer?

The risk of colorectal cancer for any patient with ulcerative colitis is known to be elevated, and is estimated to be 2% after 10 years, 8% after 20 years and 18% after 30 years of disease.

Can ulcerative colitis become cancer?

People who have ulcerative colitis have an increased risk of developing bowel cancer (cancer of the colon, rectum or bowel), especially if the condition is severe or involves most of the colon.

How long a person has had UC may also affect their risk of cancer. The risk grows depending on how long they have had UC and how severe it is. After 8–10 years of having UC, a person’s cancer risk increases by around 0.5% to 1% each year.

Can a person with ulcerative colitis get cancer?

Risk of colorectal cancer in patients with ulcerative colitis: a meta-analysis of population-based cohort studies. The risk of colorectal cancer in ulcerative colitis: a meta-analysis. Systematic review with meta-analysis: the declining risk of colorectal cancer in ulcerative colitis.
