@carrmb, I was diagnosed with Stage 2b NSLC w/ EGFR mutation in 2016. I had an upper right lobectomy followed by chemo and radiation at the same time. My Oncologist gave me steroid pills (Dexamethasone) to take twice a day the day before and after chemo. The first bag they hung during the chemo session was also Dex. You say his coughing has gotten worse, indicating he was coughing before. What's the source of his cough? Hopefully, the steroid pack is helping.
