Inflammatory bowel disease (IBD) may increase melanoma risk, a new study shows.
“Based on this data, we are suggesting that physicians appropriately counsel IBD patients about the risk of melanoma. Sun-protective measures are very effective in preventing this cancer,” says study author Siddharth Singh, MBBS, a Mayo Clinic gastroenterologist, in a news release.
Researchers determined this increased risk by performing a comprehensive search of all published studies on IBD over the last 70 years. They analyzed 172,837 patients with IBD (92,208 with Crohn’s disease; 79,360 with ulcerative colitis) to find the 179 cases of melanoma after an IBD diagnosis.
