My Dad has has completed first round of chemo and radiation for his lung cancer. (ended in 9-10) In December he was diagnosed with Radiation Pneumonitis and spent 7 days in hospital on steroids. He is tapering off steriods now and is better from other side effects of treatment especially the nausea. He is so short of breath even with his oxygen since leaving hospital. Has anyone else had this happen to them and what are long term effects you have experienced?
