A new sound wave technique which is being used to treat prostate cancer could transform the way in which the disease is dealt with in future, according to experts.

Called High Intensity Focused Ultrasound the treatment works by focusing sound waves directly on to tumours in the prostate gland without affecting surrounding healthy tissue.

Doctors working on a study into the treatment's effectiveness said it was "revolutionary" and had been shown to cause fewer side effects while delivering successful results.

Tim Dudderidge who helped run the study, which involved following 625 men through the course of their treatment, said results so far had been "extremely exciting" and could "transform" future prostate cancer care.
