HER2-Positive Breast Cancer
๐Overview
This condition occurs when an amplification of the HER2 gene causes cells to produce an excess of the HER2 protein, which can lead to more aggressive tumor growth compared to HER2-negative subtypes.
Clinical identification is typically achieved through specialized laboratory testing to evaluate the protein levels or gene copies within the cancer cells.
