Human HER2 Testing

Human HER2 testing assesses the presence of the HER2 protein, which can promote cancer cell growth, especially in breast cancer. This test helps determine if a tumor has high levels of HER2, indicating a more aggressive form of cancer. Results guide treatment options, as HER2-positive cancers may respond to targeted therapies designed to block the HER2 protein, improving outcomes. The testing process typically involves a biopsy of the tumor, where lab techniques analyze the sample to determine HER2 status. Understanding this helps tailor individualized treatment plans for patients.
