Hi
Just moving your question from the thread about me as don't want to keep bumping it up (though am appreciative of the sentiments.)
I can only report what my consultant told me- that he is treating women who have had BC, with HRT alongside their oncologists. They are using particular regimes (types of HRT) that are thought to have low / little risk.
I think if you want a definitive answer you are going to have to see a top menopause specialist - probably in London or another big city (there are a handful of them) - because your average GP or practice nurse won't know. And oncologists have different opinions too.
Hope you get some help.
