I don't think that HRT caused my endometrial cancer, but I suspect it made it spread further than it would've done otherwise, meaning I had to have chemo rather than just a hysterectomy, an increasing the risk it will return. It's well known to thickened the womb lining without progesterone, but I don't think my progesterone was being absorbed, as my period never fell into any cycle with it, I raised this a few times, but nobody seemed bothered.
When I read the medical literature it's thrown into question for me whether I should ever have been prescribed in the first place, or certainly I should've been given more information, as someone who had trouble with hormones and periods all through my adult life. I certainly think I wasn't screened enough nor monitored enough. I got it from a private clinic, not the most famous one, and I often feel the HRT thing is a bit of a cult. People have been poking fun and derision at the recent guidelines around CBT and menopause, and I'm a bit sceptical about CBT anyway, but the constant push of HRT as the only solution, and if you don't take it, your bones are going to crumble and you're going have a heart attack and get dementia does my head in! in fact, the only evidence about cognitive decline is for people with an APOE4 gene, a recent study showed no effect for anybody else. I also had a tiny spot of ovarian cancer, and although I couldn't particularly find a link around HRT one medical professional I spoke to, I can't remember who it was said she thought there definitely was a link but research was still being undertaken.
On the other hand, one of the reasons I did take it was another condition that I have whether the research does indicate that it does make a difference, but when I ask my consultant about the effects of the menopause on the condition. he said nobody had asked him before and he didn't know anything, even though it's most likely to affect women between 50 and 60, so I guess I was self-medicating because of that. No cancer in the immediate family, I no longer drink, I've always exercised, I ate healthily, I didn't think it was a risk. How wrong can you be?
