IBD Associated With Risk for Genitourinary Cancers
A pooled analysis presented at a medical conference suggests people with IBD—especially ulcerative colitis—may have higher rates of some genitourinary cancers, which could affect discussions about cancer risk and screening.
The findings are preliminary and came from a conference abstract, so they do not yet change clinical recommendations.
Adults with IBD, clinicians treating IBD patients, and researchers studying cancer risk in IBD.
What To Know
What To Know This report summarizes a systematic review and meta-analysis presented as an abstract at the 2025 Crohn’s & Colitis Congress that looked at associations between inflammatory bowel disease (ulcerative colitis and Crohn disease) and genitourinary cancers (prostate cancer, renal cell carcinoma, and bladder cancer).
The pooled analysis included 20 studies and found statistically significant associations for UC with prostate cancer and RCC, and borderline or near-significant associations for CD and overall IBD for some cancers. The article cites the abstract (Zhang Z, Polpichai N) presented at the conference.
The findings are framed as an association from pooled population studies; the authors and the news piece emphasize that future studies are needed to determine if enhanced genitourinary cancer screening is necessary for people with IBD. This article reports on research results presented at a meeting rather than a finalized peer-reviewed journal article.
If you have IBD and concerns about cancer risk, this article may highlight an area to discuss with your clinician, but it does not provide screening recommendations or clinical guidance.
Who Should Pay Attention Adults with IBD (Crohn disease or ulcerative colitis), clinicians who care for IBD patients, and researchers interested in cancer risk and screening in IBD populations.
More Context This summary is based on a conference abstract and a news report; conference abstracts may present preliminary analyses that later change after peer review and full publication. The article reports relative risks from pooled studies but does not provide individual patient-level recommendations.
Further research is needed before changing screening practice.
Conference abstracts are preliminary and may not reflect final peer-reviewed results. The news piece reports associations (not proven causation) and does not include clinical screening guidance.
