Bladder cancer patients should be given a shorter, more intense course of radiotherapy, say researchers, because it lowers the risk of the disease returning by 29 per cent. Researchers at The Institute of Cancer Research and the University of Manchester analysed data from two previous clinical trials on radiotherapy treatments. They found that giving fewer but larger doses of radiation not only reduces the risk of the disease returning, but involves fewer hospital visits - reducing Covid-19 risks. Best of all, fewer doses - resulting in 12 fewer trips to hospital - didn't lead to any increase in side effects compared with those having more, but lower doses of radiation.
