Your team would choose the best treatment for you based on lots of knowledge and lots of research. By taking extra nodes they are checking if any more are affected or not. If they really felt you needed chemo, they would have offered it. We all worry about metastases and the repeat scan in 6 months is probably more for reassurance. All of us appreciate the confusion, I know I second guessed decisions and worried that even though I didn't have nodes ...should I be having radiotherapy anyway? However once the decision is settled and you are on your way in treatment, you will start to feel more secure. Hope all goes well and medication side effects are minimal. Kath x
