@JaniieJones Have you just searched and plucked a piece on dementia and hrt out of google? Webmed is a US site it's not a reputable place to find real info. Also, in the US, they use very different types of HRT to what is used now in the UK.
Also, as a regular poster here, it's not my job to do every bit of research and post all of it. It's simply too time consuming.
I've left numerous links over time, to the BMS, the IMS and videos and podcasts with reputable drs like Panay where women who are interested can do their own research.
Re dementia, it seems logical to me that as women suffer most, and only women have and then lose estrogen, there just might be a link.
And yes, weight is an issue re cancer. But given only 10% of women use hrt and 67% of women are overweight (which increases risk hugely) the message isn't getting through, is it?
