New research presented at this year’s European Congress on Obesity (held online, 10-13 May) finds evidence that structures called inflammasomes (a part of the innate immune system that helps to regulate inflammation) could play an important role in the development of obesity-associated colon cancer. The study is by Dr. Victoria Catalán and Professor Gema Frühbeck, University Hospital Navarra and CIBEROBN, Instituto de Salud Carlos III, Pamplona, Spain, and colleagues.
