Ihave a question about how much radiation I am getting. My cancer was a half inch triple negative grade 3 stage two invasive carcinoma. Only one lymph node was invaded within the breast,my margins were clear on the other lymph nodes and my pet scan was clear. Now they are giving me thirty days of radiation,25 to the whole breast 5 days targeted to where the cancer was taken out. 60000CGYs total. Is that over kill?
