@SheIsMenopausal It's completely valid to reassess if you need HRT. My consultant suggests stopping for 3 months to see if symptoms are still there.
There is no time limit on use (there never was actually, it was just some vague 'guidance' about 2 or 5 years that was never based on anything scientific, and consultants didn't prescribe within that.)
However, although body identical HRT appears to have lower breast cancer risks, the evidence is limited. There are no real long term trials (and never will be) so the stats are observational.
There are some vocal (media) doctors who will say 'No risk at all' but that's not the case.
It's a case of weighing up your personal risk against the small (and unknown ) risks of HRT long term. Most consultants say the risks outweigh the benefits for most women.
You need to consider your risk of heart disease, perhaps dementia, and bone health.
It's a real shame that the NHS still refuses a national screening for bone health for women over 50 which would save for more lives than for example smear tests. If you can afford a private bone density scan it's worth it and will help you decide where to go with HRT.
