Endometriosis is a chronic disease that affects millions of women in the world. Endometriosis is when the endometrium normally placed inside the uterus is found outside of its natural place. This tissue may be localized in the ovaries, fallopian tubes, in the ligaments that hold the uterus, on the surface of the uterus and in the peritoneum, which is the tissue that lines the pelvic cavity.
You can also find these lesions in other locations such as the bladder, cervix, vulva, the intestines and on surgical scars.
