Hello
My son had thymoma and his thymus removed at the end of May. Some microscopic cancer cells remained in his pleura and he has to have 6 weeks of radiotherapy to zap these. He has had 3 weeks of it so far. But over the last week (his 2nd week of radio) he has started coughing a lot. Is this a normal side effect of radiotherapy to the chest? Can it irritate the windpipe or lung?
