Patients with inflammatory bowel disease (IBD) are at an increased risk of developing colorectal neoplasia (CRN), a type of colon cancer. Smoking has complex effects on IBD, reducing inflammation in ulcerative colitis but not in Crohn's disease, and is a known risk factor for CRN in the general population.
This study investigates how cigarette smoke influences CRN risk specifically in IBD patients, an area of ongoing research with significant implications for patient management and screening guidelines.
