cancer sucks and so does menopause.
everyone is different with their experience.
the women in my family never talked about menopause in front of me and when I was going through menopause I asked my aunts about their experience. none of them had any horrible tales to report; they hardly had any symptoms. at this point, i can't recall the gruesome details of menopause or chemo and they couldn't either.

it is a difficult time for so many women (and their families), but it does get better. I never used HRT. I was feeling rather well and starting a new chapter in my life, when the rug was pulled out from under me. So, I am back to the basics of exercising, eating right and thinking positively, etc.
good luck with your decision.
