New research from biomedical engineers at Vanderbilt University, published in the journal Science Advances, highlights a new method for decreasing cancer metastasis - particularly in cases of triple negative breast cancer. The research describes the team's discovery enabling modified "cell soldiers," created with the body's own defenses, to hunt down and kill cancer cells that escape during tumor surgery. Dr. Michael King, Chair in the Department of Biomedical Engineering, and director of the King Lab at Vanderbilt, joins Craig to discuss.
