My mother had undergone surgery for left breast carcinoma. Breast surgery was done after giving her 4 chemos. We have received the Biopsy report Post NACT. We were under the impression that 4 more chemotherapies were enough. However, our Medical Oncologist has suggested 12 chemotherapies for 12 weeks basis the Biopsy report. I would like to know if this is the right course of treatment. Please find attached the Biopsy, Discharge summary and other reports.
