Vaginal atrophy. Why didn't someone warn me?

Gosh thanks @Romla. I specifically asked gp what to take thats safe for me. This is a new gp i ditched the old one after she prescribed an hrt only for women past menopause. I took it for 2 years then found out i shouldnt been on it in the first place. Specially since my mum took des while pregnant with me. I never had an oncologist ibecause all my cancer got taken in the mx and i had no chemo or rads. Then i feel i was ditched a bit because i had immediate recon i became a  plastic surgery patient  the breast clinic  sort of acted like theyd passed me over. My cancer was gone so they dont seem interested in me any more. I get that. I am one of the lucky ones. I was er+ 85%  pr- but no form of hormone therapy was ever offered or discussrd. When i asked why no tamox they said 'because you dont need it' and that was it. Im pretty nervous about the other side. I had a 7cm  long area of  high grade dcis that filled half my breast that couldnt be felt or seen on mammo or utrasound except 2 small clusters of cacifications. I had been having regular mammo since i was 40. Its very scary. I will go off the remifemin then and do some more research. Thank you for taking the time to let me know. :-)   v
