    what research (or clinical trials) is being done for Breast Cancer ?
    ### Response:
    Clinical trials are research studies on people to find out whether a new drug or treatment is both safe and effective. New therapies are tested on people only after laboratory and animal studies show promising results. The Food and Drug Administration sets strict rules to make sure that people who agree to be in the studies are treated as safely as possible.
