I had mastectomy and sentinel node biopsy for invasive lobular cancer. One of three sentinel nodes had a 5mm cancer with extra nodal extension. One Radiation Oncologist wants to radiate the entire chest wall and axillary lymph nodes. Another recommends radiation to the axillary and supraclavicular nodes, and no radiation to chest wall. A third suggests considering no radiation because my cancer is in "a gray area" in terms of whether to radiate and no radiation would be within the standard of care. I am taking anastrozole. Pathology after surgery was T2N1(a) It is so difficult to know which way to go when you are given greatly different options that are each considered reasonable. Why is your radiologist refusing to radiate the lymph nodes? Did you have more axillary nodes removed than just the few done with a sentinel node biopsy?
