I have had lumpectomy with mammoplasty for stage2grade 2 breast cancer. I start radiotherapy soon to the breast and axillary nodes as one was positive. Can you please explain why they have decided to irradiate the supraclavicular nodes too? Is this common or is the problem more serious than I thought? I am currently having a break from letrozole due to having hypothyroidism converting to hyperthyroidism a nd confusing everyone with symptoms which could be caused by either of the drugs I was taking.
Thank you
