My 43 year old sister recently had a pathology report come back with atypical cells, mucin and calcium dpts. She is perimenopausal with hot flashes. She is going on tamoxifin and neurotin for the hot flashes. I on the other hand am 47 on birth control pills and also perimenopausal with hot flashes. Worried about birth control pills and my sisters diagnosis. What do you think?
