Hello. I, too, was diagnosed with grade 3, Her2 pos breast tumors in February. Chemo started 3/16. 10 of 12 chemo completed, 3 of 4 perjeta treatments complete and Herceptin ongoing. I had lumpectomy and snb on 7/10. Four nodes removed. There was no evidence of cancer. You got this. Be strong. Take it one day at a time. You will get through this!
