HER2-positive breast cancer

HER2-positive breast cancer is a type of breast cancer where cells have an excess of a protein called HER2 on their surface. This protein promotes faster growth and division of cancer cells. As a result, HER2-positive cancers tend to grow more quickly than other types. They may also be more likely to spread. However, targeted treatments have been developed to specifically block the HER2 protein, improving outcomes. Diagnosis involves testing the tumor to determine HER2 status, guiding personalized treatment options. Early detection and appropriate therapy can significantly improve prognosis for those with HER2-positive breast cancer.
