Tamoxifen and ovarian cysts

I think if they are small cysts they just leave them cos often they burst of their own accord.I had an ovarian cyst the size of a golf ball and had to have it removed(wasn't on Tamoxifen at the time).I've been on Tamoxifen for 3 years now and a recent pelvic ultrasound showed I had cysts in the lining of the uterus.My oncologist just said that's normal when you are on Tamoxifen and they are harmless and will go away when I come off Tamoxifen.It still worries me though.Good luck with the specialist and I hope you don't need any operations.
