I am due to have a lumpectomy and sentinel lymph node removal using radioactive dye. My eGFR is only 23%. After the operation I am due to have radiation therapy. Has anyone else had this done and do you know if the radiation or dye will lower my eGFR of 23%. I am very worried at the moment as I don't want to get rid of the cancer and end up having to have dialysis.
Any advice will be gratefully received
Many thanks
Eve
