I've had ground glass show up on my chest x-rays and I've never had cancer but had bronchitis plenty of times. I was told it was from that.

Follow up: went to my asthma/allerby clinic and they referred me to a pulmonologist, who said they're too small to biopsy, many things can cause them, they're inflammation i.e. infection, and they may go away on their own. I asked him if they could turn into cancer. He looked at me with a serious face and said, "It's highly unlikely." Whew! Followed up with the asthma/allergy doc and he isn't concerned, either. The onco doc didn't seem too concerned, either.

Darn the internet! Even the Mayo Clinic said they could turn into cancer! Best way to get a former cancer patient's panties in a wad is to use the C word!

Another CT in a year to see if there's any change. In the meantime I'll try various things - walking to get my breathing a little faster and maybe that'll push the infection out; no sugar (infections and cancer like it); sound therapy.

I found a soundtrack for cancer removal. I wondered if it would work on the GGOs. It worked on my kidney - I didn't know I had stones until they passed; my urine was the color of root beer.

I am glad to hear that you got good news. I can imagine how relieved you are. Take care.
