GM-CSF-secreting breast tumor vaccine
(… seh-KREE-ting brest TOO-mer vak-SEEN)
A vaccine that is being studied as a way to help the body’s immune system kill breast cancer cells. To make the vaccine, the GM-CSF gene is put into breast cancer cells in the laboratory. The cells are then treated with radiation to stop them from growing and injected into the same or a different patient. The GM-CSF protein made by the changed breast cancer cells may help the immune system kill breast cancer cells in the body.
