HER2 Positive refers to a specific type of breast cancer that tests positive for the HER2 protein, which promotes the growth of cancer cells. This means that the cancer cells have an excess of the HER2 gene, leading to more aggressive tumor growth. Patients with HER2 Positive breast cancer may benefit from targeted therapies, such as trastuzumab (Herceptin), which specifically attack the HER2 protein. Early detection and treatment are crucial for improving outcomes in individuals diagnosed with this type of cancer.
