HER2negatiivisessa

HER2negatiivisessa is a Finnish term referring to a breast cancer subtype that tests negative for the HER2 protein. HER2, or human epidermal growth factor receptor 2, is a protein that can promote the growth of cancer cells. When breast cancer cells have high levels of HER2, they are classified as HER2-positive. Conversely, if the tests show no or very low levels of HER2, the cancer is designated as HER2-negative. This classification is crucial for determining the most effective treatment strategies. HER2-negative breast cancers represent the majority of all breast cancer cases. Treatment for HER2-negative breast cancer typically involves therapies such as hormone therapy, chemotherapy, and sometimes targeted therapies that are not specific to HER2. The approach is individualized based on other characteristics of the cancer, such as hormone receptor status (estrogen receptor and progesterone receptor) and the stage of the disease. Understanding the HER2 status of a breast tumor is a fundamental step in the diagnostic and treatment planning process for oncologists and patients alike.
