Fast Growing Fibroids

how fast do fibroids grow?
referring to uterine fibroids. Can the hormones from breastfeeding cause them to grow quicker? if so, how quickly? Does anyone have any experience with this? I am breastfeeding full time, am NOT on birthcontrol and cannot get pregnant(hubby had vasectomy). I might have a fibroid but haven’t had this confirmed yet. I had an ultrasound and I’m seeing my doc soon for the follow-up. I guess I’m just nervous and never get enough time at appointments
In my case, uterine fibroids grew very fast. I had a surgery in 2005 to remove 28 fibroids of size 16 weeks pregnancy but they grew back just within 1 year as big as size of 20 weeks pregnancy.
Now I have to take another surgery to remove, may be, my whole uterus.
