New discovery may lead to 'one-size-fits-all' cancer treatment one day, researchers say. Scientists at Cardiff University say they've found a T-cell with a new type of receptor that can recognize and kill most cancers. Their findings were published in the peer-reviewed journal Nature Immunology on Monday. The discovery has not yet been tested in patients, but study author Andrew Sewell called it "an exciting new frontier." "We hope this new (T-cell receptor) may provide us with a different route to target and destroy a wide range of cancers in all individuals," he said in a statement.

Experts in the field not involved in the study were cautiously optimistic about the results. Dr. Marcel van den Brink, a medical oncologist at Memorial Sloan Kettering Cancer Center, called the discover "a very nice step forward" but said more work is needed before determining whether the research could…
