Radiotherapy doses for prostate cancer could be cut by three-quarters, trial finds

Five higher multibeam doses found to be as effective as 20 smaller doses delivered over several weeks

Men undergoing treatment for prostate cancer could be safely exposed to fewer radiotherapy sessions, a big trial has found.

The trial, conducted by the Royal Marsden NHS foundation trust and the Institute of Cancer Research in London, found that radiotherapy doses can be cut by three-quarters, meaning that five higher doses of radiotherapy are just as effective as 20 smaller doses delivered over several weeks.
