The growths are commonly referred to as endometrial implants.
Scientists aren t sure what causes endometriosis.
Diagnosing endometriosis usually involves a laparoscopy , in addition to a complete medical history, a physical exam, and in some cases a variety of other tests as well. Endometrial implants typically inset in other parts of the reproductive tract, including the ovaries, fallopian tubes, the inside lining of the abdominal cavity, and the outside surfaces of the uterus or intestines. But they can occur in almost any part of the body, including the liver, legs, lungs, and very rarely the brain. Because they re made up of the same uterine tissue that is shed during menstruation, endometrial implants break up monthly just like the endometrium does. The result is internal bleeding, inflammation, chronic pelvic pain, and the formation of blood-filled cysts and scar tissue.
