In the early 1990s, my then ObGyn gave me a prescription for hormone replacement therapy and told me to start it when my period had completely stopped. I was not having problems. I later started taking the pills and changed doctors. The new ObGyn noted a growth of something in my uterus. First 6cm and after 3 months the ultrasound showed it had increased to 10cm. She was out of the office when they called me for the results and her colleague wanted to schedule me for surgery. I had read something about HRT and fibroids, and I declined, and I stopped taking the HRT. Three months later, my fibroid had gone from 10cm back down to 6cm. I had been told that HRT does not cause growth of fibroids, but I have the ultrasounds that show differently.
