AskedPublicly Submitted Question
10/17/2015Why is the risk of breast cancer greater using combined HRT as opposed to an OC? I am 52, have extremely dense breast tissue, 3 breast biopsies (ALH) and use continuous marvelon. I have an enlarged uterus (2X the size)and interstitial cystitis. Was thinking about switching to HRT, but starting to think that my odds are better if I stay with the marvelon until age 54. I started OCP at 51.5 years (bad menstrual cramping). HOW are the OC's and HRT different, or does it have more to do with being menopausal or not menopausal?

10/17/2015I am not sure the answer is known yet. the research however demonstrated through retrospective review of tens of thousands of cases that women on HRT that was both estrogen and progesterone ran a higher risk of it causing breast cancer than those taking estrogen alone. For those at higher risk of getting breast cancer or have a personal history of breast cancer, they are not to take HRT in any form.
