I have a question regarding tamoxifen. I wondered if you may help answer some of them. I am 6 months diag and had lumpectomy with 1 node positive. I have just finished 8 cycles of dose dense chemo and will start radiation next month. My onc wants to put me on tamoxifen and i an trying to weigh the benefits with the side effects. I work out heavily and worry about weight gain and hot flashes, etc.(crazy I know)I am looking for others that can share information on their experiences with it. Also I begin radiation next month and wondered what others have experienced as far as the breast changing size. Any information would be greatly appreciated. Thanks so much.
