Study: Estrogen Treatment Risky

Women who take hormones to deal with menopause symptoms may be increasing their risk of breast cancer more than previously thought, a new study suggests. The combination of estrogen and progestin has already been linked to a higher incidence of breast cancer, but the new study, which tracked 60,000 nurses, found that any sustained hormone use (for 10 years) increases the risk—even for those women without a uterus who take only estrogen. Doctors recommend taking the lowest possible hormone dosage for women treating menopause.
