Endometriosis is a non-life threatening condition where tissue that lines the inside of the uterus is found elsewhere in the body. Endometriosis lesions can be found anywhere in the pelvic cavity: on the ovaries, the fallopian tubes, and on the pelvic sidewall. Other common sites include the uterosacral ligaments, the cul-de-sac, the Pouch of Douglas, and in the rectal-vaginal septum. Currently, there is no cure for endometriosis however, much has been done in recent years to advance the research and awareness surrounding the condition.
In rare cases, endometriosis has been found in caecarian-section scars, laparoscopy or laparotomy scars, and on the bladder, bowel, intestines, colon, appendix, and rectum, inside the vagina, inside the bladder, on the skin, even in the lung, spine, and brain. There are various theories about what causes endometriosis, however, not there is no known cause for the condition. Theories include Retrograde Menstruation, Immune System Disfunction, Environmental Factors, and Heredity. For more information, go to Endometriosis.org
