Hi Esra: I am so, so sorry that your cancer came back, and hope that now you can stay in remission. I pray, too, that you live to see your son grow up. There are in fact new treatments for HER2-receptive breast cancer - treatments beyond Herceptin and Tykerb - which hopefully will be available soon. Please read our article on these new treatments. And the very best of luck going forward - PJH
