The combination approach that Lena Gamboa, seated, Gabe Kwong, foreground, and Ali Zamat developed tags the tumors with a synthetic "flag" then uses specially engineered cells from the patient's own immune system to attack the cancer. They found their approach worked against hard-to-treat breast, brain, and colon cancers. it also turned the cancer into an immune system training ground, allowing the body to recognize and fight any tumors that regrow.
