Her2+ Metastatic Breast Cancer
Her2 is a growth-promoting protein found on the outside of all breast cells. If they have a higher than normal level of Her2 they are called Her2-positive. Her2+ breast cancers tend to grow and spread faster than other breast cancers, but are also more likely to respond to treatment with drugs that target the Her2 protein. Women with newly diagnosed invasive breast cancers should be tested for Her2. According to the American Cancer Society, testing is usually done at the time of the biopsy and is usually tested with either immunohistochemical stains (IHC) or Fluorescent in situ hybridization (FISH).
The National Comprehensive Cancer Network, or NCCN, has released two patient educational videos on Her2+ metastatic breast cancer that we have included for you below. Cancer Registrars may also find these videos to be informative.
