I was a smoker, but smoking has nothing to do with lymphoma. My doctor is very optimistic that I will beat this, and I actually feel real good. I have been lucky with the aftereffects of chemo, I havent had any nausea, just sleep alot. I am on round 2 of 6, so it will be a long summer, but after that I get to watch my kids grow, so it will all work out.
But back to you, if the cough doesnt go away, and you have lost some weight, go get a chest xray just to make sure.
