I am going to see pulmonolgist for his opinion. I think Lolly you are right about PET scan, so that will be on list to ask onc for next visit. Hope it's just fibrosis. Thanks, Velva

I appreciate the repsonses and suggestions. She actually exercises quite a bit but could probably spend more time relaxing, although it's hard with 3 kids (1 being me!). I'm concerned because she has had a tough time recently fighting off a couple of infections.

Thanks, Eric
