Hysterectomy: Surgery will allow the gynecologist to see if a cyst has been the result of edometriosis and results in a collection of old blood
. For a woman who has already given birth to her children, this case of "chocolate cysts," or an endometrioma, can only be cured by a hysterectomy and removal of both ovaries. This is usually necessary rather than optional in order to resolve the problem forever. According to the severity of disease, the patient's age, and potential other pelvic complaints, removal of the ovary may be the most indicated course. The surgery is also obligatory for ovarian cancer as the patients have a low rate of survival otherwise.
