FACTS:
The researchers took a range of killer t-cells from the body and tested them against bacteria. One of the killer t-cells was so effective, it killed all of the cancer cells and not just the ones with bacteria inside them. They tested it against other types of cancer and it was effective against all of the different cancers.
They hope to have human clinical trials in a few years as they try to understand the exact mechanism being used to identify cancer cells, while differentiating from healthy cells.
