Endometriosis is a condition where tissue, similar to the tissue that normally grows inside the uterus, also grows outside of the uterus. The tissue inside the uterus is called "endometrium" and the tissue outside of the uterus is called "endometriosis". The most common places where endometriosis occurs are the ovaries, the fallopian tubes, the bowel, and the areas in front, in back, and to the sides of the uterus.
Some women with endometriosis have few or no symptoms while others have pain or difficulty becoming pregnant. There is no cure for endometriosis, but there are several treatment options. The best treatment depends on your individual situation.
