  schema:description "An extra dose of radiotherapy aimed at the place the lump came from cuts the chance of the cancer returning in that breast by about a third, but it does not help anyone live longer and it triples the chance of the breast becoming hard and scarred. That trade is the reason the extra dose is offered by risk rather than to everybody."@en ;
