Im sorry to hear that Chemo hasnt done anything to shrink your tumour but I guess of you look at it from a refillable cup perspective, although the chemo hasnt shrunk the primary it hasnt continued to spread either. As for the lymphodema, 6 years ago I had mastectomy, 26 lymph nodes removed plus radiation with boosts to my tumour site and clavicle. No lymphodema. I now have mets (we wont go there) and am again having radiation to clavicle and still no lymphodema. Never had to wear a compression bandage either. Hang in there. Have your surgery and take each day a step at a time. We are ALL here for you.
