@koalaknickers I think what a lot of people don't realise is that the link you posted to the meta analysis actually includes ALL the trials over the past 20-odd years.
It includes the flawed WHI, the flawed Million Women study AND several trials that are not even peer reviewed.
The most recent analysis did not include many women using Utrogestan (it was a tiny, tiny number like 30 out of hundreds of thousands of women).
There is a separate analysis of Utrogestan and a statement by the BMS which says that in all probability it is safe for 5 years with no added BC risk.
The WHI trial is not regarded as obsolete. I've never read of or heard any menopause consultant refer to it that way.
It did include many errors in the design (previous health issues, age of subjects, - starting in their mid 60s - previous HRT use, weight, smoking to name some.) It wasn't just about using conjugated equine estrogen.
That trial did show that women on estrogen-only (no progestogens) have less BC than the non-HRT population, and this is confirmed by other trials since.
My advice to anyone wanting to use HRT and who has concerns about the BC risk should see a specialist consultant to discuss them.
The information online does not show the whole picture because it's often a summary.
In addition, the trials are always retrospective / observational. There is no single double-blind, placebo trial that's been done on HRT. Menopause experts are pushing for these. All the good specialists admit that the evidence available is unclear and nobody really knows the risks, which may or may not exist. The best they can say is that the risks appear small, and for most women the benefits outweigh the risks.
