Welcome to the forum @TabooGal . It's such a shock, isn't it? I don't have anything to add to what is here but if you're unsure of any information you've been given then ask - surgeon, bc nurse or your GP. You won't get the definitive answers about your tumour and the nodes until the biopsy comes back from the operation. Then, after recovery from that, your suggested treatment will be outlined for you. Not everyone chooses to, but it can be a good idea to take someone you trust with you to your appointments. It's easy to be focusing so much on one thing that you don't hear the next. And take a list of questions so you don't walk out forgetting the one thing you really wanted the answer to.
