Did scientists engineer tumor-eating bacteria?

Analysis Reasoning

Scientists at the University of Waterloo engineered bacteria to invade and consume solid tumors from the inside out by exploiting oxygen-free tumor cores, with genetic tweaks enabling survival near oxygenated edges. Multiple studies confirm bacteria-based therapies that eradicate tumors in mouse and human models through direct consumption or immune activation.
