Breast cancer?: where is the tumor? I assume this is breast cancer, correct? ER-/PR-/her2neu 3 + cancer. will need to get staging scan to evaluate if there is any spreading of cancer to other organs. if no metastatic disease- definitely will need to get chemotherapy PLUS herceptin (trastuzumab) ( her2neu inhibitor) - then surgery -then radiation therapy- then maintenance herceptin (trastuzumab). Please discuss further with oncologist .

Her 2 neu pos ER PR-: The cancer is questions is not sensitive to hormonal therapy or ablation. I presume this is breast cancer. It stains strongly for Her 2 neu. This means it requires Herceptin (trastuzumab) based chemotherapy as big as it is. A common chemotherapy given in this situation is Carboplatin , Docetaxel and Herceptin (trastuzumab). one cycle every 21 days x for 6 cycles. This is before the definitive surgery, mastectomy.
