For women, is 10yrs still the cut off as when to start E2 therapy? I was told not to start women on E2 therapy if it has been over 10 yrs since going though Menopause of having a Total Hysterectomy. The reasoning behind this was that it would increase their chances of developing Breast CA. Is this guideline still good to follow?
I agree with Dr Fete. It is never too late to start BHRT. My general policy with hormones is to start low and work up to avoid side effects.
Oral synthetic estrogens will stimulate metalloproteinases and that is what is implicated in cardiac events when starting BHRT. That is where the concern about starting estrogens in older women comes from. If they has risk factors for athersclerosis and get started on a commercial HRT, it is not graded with a gradual increase and it will weaken vulnerable plaque. This should not be an issue with oral Estradiol, which is metabilized very differently than oral commercial estrogens. Oral Estradiol has low risk but I still like to start low and work up in dose.
