Ovraian Cysts and high estrogen levels

I'm 28 and was diagnosed with Breast cancer over a year ago.
I am now on Tamoxifen and have been on it for 5 months.
Since being on tamoxifen i have developed 5 cysts that were not there before i started taking the tamoxifen as i had regular scans last one was in July.
My blood tests results have also came back with extremely high estrogen levels, 5000+, my GP and oncologist have never seen this before and im really thinking hard about not taking the tamoxifen as with estrogen levels this high and cysts developing surley the tablets can not be working.
I have not had any children and really want to in the future and if i continue taking these tablets i doubt i will be able to.
Any help? thanks


This discussion is related to Tamoxifen and high estrogen or ovarian cysts?.

Well the purpose of Tamoxifen is to block the production of Estrogen which obviously isn't happening in your case. I think I would have a serious discussion with your Oncologist about this; perhaps one of the other drugs would be more appropriate in your case.  I too have never heard of this ..   Regards
