I was on HRT for over 10 years, then developed an oestrogen positive breast cancer. A lot of you have heard this from me before on similar threads, but for those who haven't - I had chemo, radiotherapy, five years on Tamoxifen etc. etc. as I was recovering, the first reports suggesting that HRT, years on the pill and so on might increase the risk of BC. And it does look possible. (I was an Ambassador for CRUK for many years, so have some knowledge.)
However, I vividly remember the horrors of the menopause that drove me to HRT. It wasn't so much the physical symptoms, which were few, apart from weight gain and some hot flushes, (must add that I haven't eaten meat or fish and now little dairy produce)
It was the dreadful psychological / mental problems I went through. Quite honestly, looking back, it was like the worst PMT you can imagine, multiplied to n. I thought I was going mad. And I was working full time. HRT solved it within a week.
So - what choices would I make about HRT, knowing what I know now? I cannot say, in all honesty.
