What is the deadliest form of breast cancer? Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it’s found, and is more likely to come back after treatment than other types of breast cancer.
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.
Is it better to be HER2-negative or 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.
What are the 4 types of breast cancer? Types of breast cancer include ductal carcinoma in situ, invasive ductal carcinoma, inflammatory breast cancer, and metastatic breast cancer.
