These results mean the growth of the cancer is not fueled by the hormones estrogen and progesterone, or by the HER2 protein. So, triple-negative breast cancer does not respond to hormonal therapy medicines or medicines that target HER2 protein receptors. Still, other medicines are used to successfully treat triple-negative breast cancer. For doctors and researchers, there is intense interest in finding new medications that can treat this kind of breast cancer. Studies are trying to find out whether certain medications can interfere with the processes that cause triple-negative breast cancer to grow.
