Tammy, just a small clarification: Herceptin and Perjeta are not hormone-based immunotherapies. They’re for HER2-pos cancer and target the HER2 receptor, which is not a hormone receptor. If someone also has ER or PR positive receptors, then you’d get other meds such as AIs to block those.

For ER-negative, HER2-positive breast cancer, treatments often include targeted therapies like trastuzumab (Herceptin), pertuzumab (Perjeta), or ado-trastuzumab emtansine (Kadcyla). Chemotherapy is also commonly used, sometimes in combination with targeted therapies. Surgery and radiation may be part of the treatment plan Show Full Answer

Always consult your oncologist to tailor the best approach for your specific case.
