First I have heart and lung conditions amongst other condition.
In the 90s I was diagnosed with Polycythemia and a scar on the lung, just a scar as far as I know.
The Polycythemia hospital specialist said it was just the high point of normal. I was relieved as the treatment is not great, That is never mentioned any more. Although Chest Clinic said it showed in my bloods.
A scar on the lung, is more the point in this post - My GP told me I had a scar on lung after a chest x ray and chest specialist also told my I had a scar on lung.
No mention of this in medical records - COPD or Emphysema are mentioned.
So I googled scar on lung and I get Cystic Fibrosis - I think I can discount that.
It also mentions Fibrosis - I never see that term on my GP record I can access on line.
Question is What is a "Scar on the lung" and is it a condition of it;s own, or does it fit under the COPD umbrella?
