Wow! I hate to say unkind things about your Doctor but showing some major ignorance on the subject of female health. In 2023 there was a study stating that vaginal estrogen does not absorb systemically so there is no additional risk for breast ca. Both my Oncologist and gynecologist agreed that I can use estradiol without raising my risk for reoccurrence. It is KNOWN to help with vaginal dryness and urinary incontinence and lowering the risk for UTIs. Best of luck to you getting the help you need and deserve.
