New research suggests that no matter how hormone replacement therapy is given, it increases the risk of ovarian cancer.
Hormone replacement therapy, consisting of estrogen, progesterone, or both, and used to relieve the symptoms of menopause, has been linked to breast cancer, Dr. Lina Steinrud Morch, from Rigshospitalet, Copenhagen, Denmark, and colleagues note in their study. Some studies have suggested that it could raise the risk of ovarian cancer.
Morch's team studied more than 900,000 Danish women who were 50 to 79 years of age from 1995 to 2005. None of them had tumors that grew in response to hormones, and none had had their ovaries removed during a hysterectomy or for other reasons. MORE>>>>>>>>>>>>>>
