@francesca1 Welcome to Mayo Connect - we are a community of patients and caregivers who share our journey and experiences.

Lung diseases and their progression are highly variable, so any estimates I could offer would be purely a guess, not backed by any science or fact. The question you are asking would be better addressed to your care team, as we are not medical professionals, and don't know the details of your current conditions and your medical history.

What have your doctors told you to expect? Are you on oxygen full or part time?
