Chlebowski RT, et al. - Researchers examined how persistent vasomotor symptoms (VMS; including hot flashes and night sweats) are associated with breast cancer incidence and mortality in a sample of 25,499 postmenopausal women aged 50-79 years in the Women's Health Initiative without current/former menopausal hormone therapy use who had information on VMS status (never vs persistent). In all, the investigators identified 1,399 incident breast cancers were over 17.9 years of (median) follow-up. According to findings, breast cancer is more likely to be diagnosed in women with persistent VMS vs women who never experienced VMS, but are not more likely to die from breast cancer.
