Is herceptin (trastuzumab) just can heal breast cancer?

Herceptin (trastuzumab): Herceptin (trastuzumab) is approved for the treatment of early-stage breast cancer that is human epidermal growth factor receptor 2-positive (her2+) and has spread into the lymph nodes, or is her2+ and has not spread into the lymph nodes. If it has not spread into the lymph nodes, the cancer needs to be estrogen receptor/progesterone receptor (er/pr)-negative or have one high risk feature.

Will help: Certain types of cancers called her 2 + cancers in those cancers her protein stimulates cancers cells , trastuzumab ( Herceptin ) a monoclonal antibody interferes at receptor site , cancer cell multiplication ( in way you can call it ' heal breast cancer ' in layman terms )
