Hi, my pathologist report stated that my margins 'could not be considered to be clear', and the margin was close to the surface. My oncologist and radiologist told me this means there is a high chance of microscopic disease, and higher risk of reoccurence of 75-80% in the left side (had a mastectomy). Because of this, I have to have radiation (which I am waiting for) to the chest, axilla and clavicle. I was told the radiation will not prevent a reoccurence due to being so high-risk, but it will minimize the chance to about 35%. I had lymph node involvement and am age 45 at time of diagnosis. Your age, 45 and under, lymph node involvement, grade of tumour and margins when added up decide your risk factor, and chances of reoccurence. All factors combined make me a high risk for reoccurence. Hope this helps, but maybe you can ask your doctors...I did! Good Luck.
