Her -2 neu positive patients will require herceptin / trastuzumab therapy. Her 2 neu 3+ will respond to this therapy. As these kind of cancers have more chances of recurrence (cancer return). This therapy is given to reduce chances of recurrence. Better to take all injections. This targeted therapy is related with seriousness of heart problems. So your doctor will check signs of heart problems before, during and after treatment. Infusion reactions are like chemotherapy drugs. Like lung problems, low white blood cell count etc. This therapy is given along with chemo drugs. And in her 2 neu 3+ patients it is recommended.
