A newly-discovered part of our immune system could be harnessed to treat all cancers, say scientists.

The Cardiff University team discovered a method of killing prostate, breast, lung and other cancers in lab tests.

The findings, published in Nature Immunology, have not been tested in patients, but the researchers say they have "enormous potential".

Experts said that although the work was still at an early stage, it was very exciting.
