Endometriosis may increase one’s risk of developing ovarian cancer by more than fourfold, researchers found in a study published on July 17 in the Journal of the American Medical Association (JAMA).
Endometriosis occurs when tissues lining the inside of the uterus also start growing outside the uterus. This tissue thickens, breaks down, and bleeds with each menstrual cycle. But having no way to leave the body, the blood becomes trapped, potentially causing painful periods, heavy bleeding, abdominal pain, and even infertility.
