Hi.. My aunt got diagnosed with Breast cancer last year. After chemo we were advised by the doctor to continue with Herceptin. We are using BICELTIS(herceptin drug available in India). Recently Biocon has got FDA approval for their herceptin drug. Is it advisable to switch to it from Biceltis? We are having this question due to the financial constrain; The cost will reduce 20K per vial. So any suggestions will be really helpful.
