I am very interested in what your oncologist recommends, and what you finally decide. I had a lumpectomy on 6/2, with 3 lymph nodes removed, which were clear. Am on Letrozole right now. Radiologist told me that based on Onco score and other indicators she did not feel that radiation would be of much benefit. Statistically, the recurrence with radiation is 1%, without radiation 4%. She also told me that this is not a time sensitive decision I have/had to make right then and there. For now I’m declining radiation treatment, but the effective window stays open for about 6 months after lumpectomy. So still an option in the next few months if I change my mind - or my oncologist changes it for me.
