Contents of Endometriotic Cysts, Especially the High Concentration of Free Iron, Are a Possible Cause of Carcinogenesis in the Cysts through the Iron-Induced Persistent Oxidative Stress

Abstract

Abundant free iron in the contents of endometriotic cysts was strongly associated with greater oxidative stress and frequent DNA mutations. A long-standing history of the RBCs accumulated in the ovarian endometriotic cysts during the reproductive period produces oxidative stress that is a possible cause for the malignant change of the endometriotic cyst.
