My DD has just started on HRT. I've had breast cancer (twice) my mum and her sister both had breast cancer.
We don't carry the gene which leads to breast and ovarian cancer. DD has had breast screenings every two years since she was 35 or so.
She still decided to go onto HRT at 49 years old. Her reasoning for doing so seem sound to me. She was weepy and not sleeping well at all. Flushes, night sweats etc etc. She is very aware of the risks but has decided that the benefits (protection from cardio vascular disease and osteoporosis) out wheigh the risks.
I agreed with her 100%. Two years ago I declined to take a drug prescribed to me after my last cancer because it made me super anxious. I was told that the drug (letrazone) would help ensure the cancer wouldn't come back.
Maybe it would. But I would have been verging on suicidal within a couple of months.
Nothing in this world is risk free, in my view. All I think we can do is arm ourselves with the best info we can find, and go for it.
I'm my case, I decided that is sooner live for less time, but to enjoy what time I had, rather than live longer in a constant state of anxiety.
