I didn't think I would be back posting on here. I just wanted to know a bit more about COPD. My Son has recently been diagnosed with the early stages of it. Of course I'm a bit worried because my Husband had IPF. Is it certain that this will get worse or can it be controlled? He has been a smoker for years and I think he's got a problem with giving it up. He has cut down a lot though. Thank you.
