Her2 positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 her2. These cancers tend to grow and spread faster than other breast cancers but are much more likely to respond to treatment with drugs that target the her2 protein. Er pr and her2 routinely available in breast cancer specimens are reliable inexpensive and useful for therapeutic decision making and the results of these tests are recorded in cancer registries allowing for population based research which make them a reasonable substitute for the more expensive molecular subtyping 8 9.
