Back this time with local skin infiltration

Hello ! I am back six year after lumpectomy and brachy therapy. This time same breast but close to surface that it grew into the skin. Per my pet scan, all other lymph and organs are clear. They lost my node during my unilateral mastectomy. Stage IIIA -IV.
Not sure how to get final stage. Onco dx pending. Anyone else like me.🫶🏻
