yes. It has been found to increase the risk for BC, which is why so many women went off their
long-
term HRT use a few years back, and why doctors now recommend that HRT (esp. combined HRT) be used at the lowest dose possible for the shortest time possible. (Didn't your doctor advise you to go off the hormones after the atypicla ductal cells were found?)
Bisphosphonates (Fosamax, Reclast, etc.): no.
