tamoxifen with frequent menses, recomending hysterectomy.

[sddinkinsmom]

I am a 37 yr. old. I was DX with HER 2+ 1 yr. ago in Jan. 2014. After neo-adjuvent chemo and bilat mastectomy, 5 weeks of radiation and 1 yr. of Herceptin....also tamoxifen for the past 7 months. I am having frequent menses....every 2 wk.s to 4 weeks. OBGYN did U/S with biopsy(which is not back yet.) Still she would like to do a total hysterectomy and oncologist agrees. U/S shows still ovualting and frequently. Advice on a oophorectomy vs total hysterectomy would be great? Also wondering if anyone else has had this go on while on tamoxifen? Oncologist would take me off of tamoxifen and try a aromatase inhibitor if oophorectomy. Feeling a bit overwhelmed with the side effects listed with a total hysterectomy. Any input would be appreciated?
