A new study on mice has found that giving a dose of common antibiotic not only helped immune cells kill tumours that were directly treated with radiation but also kill cancer cells that were further away in the body paving the way for researchers to test the approach in a human clinical trial. The study was published in the Journal of Clinical Investigation. More than half of all patients with solid tumours undergo radiation therapy at some point during their treatment. In recent years multiple studies have shown that giving patients higher doses of radiation over the course of fewer
