My strength is great! I really want to bump up my upper body training, but my surgeon, doctor and the nurse navigator are all very much against too much too soon due to the threat of lymphoma. I've been back to lower body and core training since about 3 weeks out. I am lucky that I have full range of motion and no pain. I think that was because I went into this being in shape and also due (and this is just a guess) to my small size. It's not as though I had large breasts and so, the mastectomy scar is only about four inches long. My surgeon did an amazing job.
