There are various forms of HRT and not all cause an increase in cancer. It’s a shame that notion has stuck around when it could be so helpful for so many women: bone density, hot flashes, vaginal atrophy, etc.
They do tend to cause an increase in blood clots though. The risk is manageable in relatively fit women. In overweight/sedentary women that gets a bit harder to balance out.

That risk factor is specific to the oral route, and/or conjugated equine oestrogens. Injections, patches etc. of synthesised oestrogens don't seem to have that problem. https://www.bmj.com/content/364/bmj.k4810
> Transdermal preparations were not associated with risk of venous thromboembolism, which was consistent for different regimens
