I have to say that as someone who's been through breast cancer herself I can't quite understand how anyone can make such a definitive statement about what HRT would or wouldn't have done - cancer is notoriously unpredictable. My cancer was triple negative so I'm able to take HRT, but obviously by doing so I'm putting myself at the same risk as anyone else of developing a new, hormone driven cancer. However, my menopausal symptoms have been so bad I figure the (small) risk is worth it - quality of life is important too.
