What does HER2-negative mean in breast cancer? In normal cells, HER2 helps control cell growth. Cancer cells that are HER2 negative may grow more slowly and are less likely to recur (come back) or spread to other parts of the body than cancer cells that have a large amount of HER2 on their surface.
What is the survival rate of HER2-negative breast cancer? Survival rates can vary based off of the subtype of breast cancer that you have. A publication from the American Cancer Society reports 5-year survival rates for HER2-negative breast cancers as: 92 percent for HER2-negative, HR-positive breast cancer. 77 percent for triple-negative breast cancer.
What treatment is used for HER2-negative breast cancer? Hormonal therapy is considered the standard initial treatment for HER2-negative metastatic breast cancer that is also hormone receptor-positive. It is often given in combination with targeted therapy. However, chemotherapy may also be given. A clinical trial may also be an option for treatment at any stage.
Is HER2-negative better than positive? Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein.
