doctors locate the tumour, guide – with maximum precision – the seed to the sight of the cancer, then use the scanner’s radio waves to heat it up to the point where it destroys the surrounding cancer cells. So far, the technique has effectively treated brain tumours in pigs and the team hope to trial it on humans within two years. As well as killing fewer healthy cells than other treatments, the therapy is
extremely quick. “We can get through a tumour in ten minutes,” said Professor Mark Lythgoe, launching the technology at the Cheltenham Science Festival.
