I just joined this site so bear with me. I am 29 and was diagnosed with well-differentiated invasive ductal carcinoma in my left breast. I had a partial mastectomy a week ago. Path reports came back as being ER+, PR+, and HER2-. No lymph node involvement. So, I will be doing 6 weeks of radiation for sure. Am in process of doing Oncotype DX test for need of chemo. In addition, I have been advised to take Tamoxifen. This is the only thing that REALLY worries me, for some reason. I have been reading previous posts from people taking Tamoxifen and it scares me. I am wondering if there is anyone out there close to my age that is taking it and what your experience has been like??? Also, any advice or alternative treatments out there anyone knows of???
