Although endometriosis is considered a benign condition the cellular, histologic, and molecular data strongly demonstrate that endometriosis has neoplastic characteristics. There is strong evidence that endometriosis shares striking features with malignancy like normal tissue dissemination, invasion, and organ damage, as well as new vessel formation (neoangiogenesis).

Several mechanisms have been proposed to explain the occurrence and worsening of endometriosis. Classically, it is believed that retrograde menstruation causes endometriosis. However, the presence of endometriosis in newly menarcheal or pre-menarcheal girls cannot fully explain this early onset endometriosis.…
