The HER2 test is a diagnostic test used to determine the level of human epidermal growth factor receptor 2 (HER2) in breast cancer cells. In Delhi, as in other parts of the world, the purpose of the HER2 test is to help guide treatment decisions for individuals with breast cancer.
HER2 is a protein that is overexpressed in approximately 20% of breast cancers. High levels of HER2 can indicate a more aggressive form of breast cancer that is more likely to spread and recur. Therefore, determining the HER2 status of a breast cancer tumor is an important step in developing an individualized treatment plan.
If the HER2 test indicates that a patient's cancer cells have high levels of HER2, the patient may be a candidate for HER2-targeted therapies such as trastuzumab (Herceptin), pertuzumab (Perjeta), or ado-trastuzumab emtansine (Kadcyla). These drugs can specifically target and inhibit the HER2 protein, potentially slowing or even stopping the growth of cancer cells.
In summary, the purpose of the HER2 test in Delhi is to help guide treatment decisions for individuals with breast cancer by determining their HER2 status and identifying those who may benefit from HER2-targeted therapies.
