sound reason to stop hormone replacement?

I’m 54. The only way I know I went thru menopause is, my periods stopped. Otherwise, I feel exactly the same as I ever did.

However, my good friend is in her 70s. She’s been on hormones since she was 53. Recently, her doctor refused to prescribe any more hormone replacement for her. My friend does not smoke, and has no history of breast or uterine cancer in her family.

Once the hormones were stopped, her cognition and mobility both took severe hits. She found some of her old hormone pills in a box somewhere, and as soon as she took them, her thinking and stamina came back.

Yet no doctor is willing to let her keep taking them. Why is this?

I should mention that this is not a doctor that is familiar with her over time, but a clinic doctor, and another clinic doctor.
