Core tip: Patients with inflammatory bowel disease (IBD) and cancer represent a challenging population. Gastroenterologists and oncologists caring for patients with IBD and cancer are increasingly confronted with questions regarding the management of IBD after a diagnosis of cancer, and conversely, the management of cancer in patients with IBD. This review seeks to explore the characteristics, risks, and pathogenesis of cancer in patients with IBD, and to evaluate the data on patients with IBD and cancer, including the interaction between IBD and cancer treatment.
