Is There A Higher Risk of Skin Cancer if you Have Crohn’s or UC?


If you follow me on instagram you probably saw my photo from last Thursday where I had a very minor surgery to have some suspect looking areas removed from my back. Is there a higher risk of getting skin cancer if you have Crohn’s disease or ulcerative colitis? So happy you asked! Here is what you need to know about Inflammatory bowel disease and skin cancer risk.

What are the risks?

All patients with Crohn’s disease or ulcerative colitis have a slight increased risk for developing skin cancer compared to people who do not have IBD. There is a 29% increase in risk for the type of skin cancer known as melanoma, and a 46% increase in risk for the type of skin cancer called nonmelanoma skin cancer (NMSC). Patients with Crohn’s disease are more at risk compared to patients with ulcerative colitis.

Furthermore for patients being treated with thiopurines, the risk of developing NMSC increases, compared to patients being treated with anti-TNF biologics who are more at risk for developing the melanoma skin cancer type.
