@dolphina3 thank you so much. On further advanced fish test, she is found to be HER2 positive and amplified .
Doctor (Onco) had now prescribed weekly chemo plus phesgo drug (once in three weeks) for 18 cycles and then will undergo mastectomy of single breast followed by radiation. She is now admitted today and will start with the treatment ( install chemo port and 1st cycle). Hope she is able to cope up and tolerate.
