Larry Norton, Deputy Physician-in-Chief for Breast Cancer Programs at Memorial Sloan Kettering Cancer Center, explains that researchers are taking a new approach to selecting the most-effective treatments for women with breast cancer. Recent studies suggest that information about RNA – which plays a key role in protein formation – can help doctors accurately predict whether breast cancer will respond to hormone therapies that block receptors for estrogen and progesterone. Doctors can use these insights to determine the risk that breast cancer will spread, and choose medications that may help prevent the cancer from spreading.
