Treatment of a Brenner tumor of the ovary includes surgery to remove the tumor.The age of the patient may help to determine the extent of the operation. For instance, women who have yet to go through menopause would immediately begin to experience menopause if both ovaries are removed. The ovaries produce hormones that regulate a woman's menstrual cycle; it is the loss of these hormones, either naturally or by the removal of the ovaries, that causes the signs and symptoms of menopause. Women who take low doses of hormone replacement drugs after surgery up until the age of 50 may reduce the chance of having the symptoms typically associated with menopause. But hormone replacement therapy has risks of its own. It is recommended that women who are thinking about taking hormone replacement therapy discuss the benefits and limitations of this therapy with their personal physicians.
