Comments:
Human epidermal growth factor receptor-2 (HER2) promotes the growth of cancer cells. HER2 is also known as c-erB-2 and Her2/neu. Tumours that are HER2-positive tend to grow more quickly than other types of cancer. HER2 status is an important prognostic marker and predicts the response to several therapies.
