Though the pancreas is an organ with little exposure to sex hormones, one form of pancreatic cancer affects specifically women, often young. How is this possible, even though the pancreas ? This pancreatic cancer, known as "mucinous cyst", has strange similarities with another mucinous cancer, affecting the ovaries. A new paper has a plausible answer. Both tumors originate from embryonic germ cells. While still undifferentiated, these cells migrate to the reproductive organs. On their way, some can mistakenly stop in other organs, bringing a risk of tumor that may occur 30 years later.
