Roughly 130,000 women nationwide are undergoing treatment at hospitals for endometriosis, a figure higher than that for other diseases such as cancer or diabetes, according to results of a survey released Wednesday by the Health and Welfare Ministry.

Wednesday's probe was the first attempt to track on a nationwide basis the disease, which causes abnormal growth of uterine tissue.
