I am a 46 year old female, premenopausal. I had a lumpectomy for an intraductal and incasive moderately well-differentiated ductal adenocarcinoma - clean lymph nodes, clean margins, ER+, PR+, Her2neu negative, family history of breast cancer (sister, aunt, cousin). My oncologist suggests just radiation and tamoxafen OR radiation, ovary ablation, and tamoxafen. The second opinon oncologist said chemo, radiation, tamoxafen. The reason for not suggesting ovary ablation was that "we usually don't do it in this country". Is one better than the other? I can't find much on the side effects of the ablation - is it different from natural menopause? Are there articles to read about this strategy?
