Abstract

INTRODUCTIONInflammatory bowel diseases (IBD) are increasingly recognised worldwide. Besides their direct impact on patients and healthcare, they carry additional risks, through both disease and therapy complications. One of the major concerns regarding IBD's natural course and medication impact is the potentially increased risk of developing cancer. On the one hand, most evidence suggests that IBD patients do not harbour an overall higher risk of cancer.1–6 On the other hand, certain cancer subtypes may be more frequent in this population. Indeed, some studies point towards an increased risk of colorectal cancer in IBD,4,7 while others indicate otherwise or suggest that the increased risk is confined to specific subsets of patients.5,6,8–10 Other organs reportedly more affected in IBD are the skin, specifically regarding non‐melanoma skin cancer (NMSC),8,9 which may be the most common cancer in these patients5; the pancreas11 and maybe the breast.6,8 Also, in Crohn's disease (CD), haematological neoplasms,8 renal cell carcinoma,9 cervical9,12 and trachea/lung cancer6 and, in Ulcerative Colitis (UC), prostate9 and thyroid13 cancer may be more common.Another concern is the increased risk of cancer attributed to IBD medication, such as NMSC,8,14–16 urological and haematological neoplasms8,17 associated to thiopurines and the debatable increase in melanoma and lymphoma risks with
