I had a mastectomy with all axillery nodes removed .Tumer was a 3 mm incapsulated. The nodes were all clean and the margins were all clean. I am having 8 treatments of chemotherapy to be sure that no cell could have escaped into the blood stream . Radiation therapy was also mentioned ( 8 weeks @5 treatments a week with 5 min. treatments ) If the site was clean is Radiation really necessary as long as I do the Chemo? All my scans are clear.
