HER2-Positive
HER2-positive breast cancer, sometimes called HER2-amplified breast cancer, gets its name from the human epidermal growth factor receptor 2
gene, or HER2. It is sometimes called HER2/neu. Between 15 and 20 percent of breast cancers are HER2-positive.
gene, or HER2. It is sometimes called HER2/neu. Between 15 and 20 percent of breast cancers are HER2-positive.Both the HER2 gene and the HER2 protein are part of normal cell growth. They are seen in the breast cells of people who do not have cancer. But sometimes mutations, mistakes in a cell’s DNA, cause the body to make too many HER2 proteins. This can cause breast cells to grow faster than normal, which can lead to breast cancer.
