Hi @BDS I was diagnosed last year, age 32, Stage 1 Grade 2 ER+ PR+. I had the lumpectomy, radiation therapy and am now taking tamoxifen daily and on zoladex injections. I have always felt very confident that my treatment plan is correct for my diagnosis and had complete faith in my surgeon who did not believe the mastectomy would offer any further benefit. He explained to me at the time that there is such a thing as 'over treatment' and to put me through the trauma of a mastectomy and/or chemo would cause more complications that it would add benefit. I hope this helps x
