hi lorraine, although i went through menopause with no side effects before bc (I know ,i was the lucky one), the doc told me i would go through it again, and if i did once again i was lucky with no side effects, i know a few of the women on here are going through it, and although it is not nice, it seems to be a common side effect of bc, as i am sure you will be hearing from those that know better, one thing i can say is, make sure you ask your doc or professionals anything that is worrying you, keeping it in because we think it is a stupid question to ask is not good for us, (especiallly in the middle of the night when we cant sleep because we are worried about it), so as we always say on here, no question is silly, we all have our fears, and hving gone through the bc journey we all need to know whats happening with our bodies, good luck with the chemo next week, and feel free to come on and shout, scream, laugh or cry, on here, there is always someone here to support you. keep in touch, and please feel free to add me to your contact list, regards Moira
