I've just had my lumpectomy and sentinel node biopsy and get further results tomorrow and feel the same as you, I think I'm just going along with what they say neds to be done and putting my trust in the experts. Only close family know, I've known about 6 weeks and do not feel as though the rest of the world need to find out, I'm not sure if the full extent has sunk in or it's just my way of facing things, under my arm is very sore it's like a burning sensation but I've read this is the norm, hope it all goes well for you x
