My mother has breast cancer in left breast. Er and pr negative and her2 positive. First she has taken 8 cycle of chemotherapy with herceptin drug and after that surgery. Now taking herceptin drug for every 21 days for up to 10 cycles. Now 2 cycles of neo adjuvant therapy over. And parallely doctor Wil going to give 6 cycles of radiationtherapy in the next month. My mother tumour size was 6.5*5*5.5 cm and cancer involved in lump node.
My question is whatever the procedure we are following Is correct or not?
I read that due to herceptin more recurrence chances will be there. To avoid recurrence what are treatment we have to take?
What might be the survival rate of this stage?
Please reply
Thank you..
