Hello. I'm 24 non smoker or drinker. I recently had a CT scan with thorax and it shows I have 5cm lung cyst with air fluids. I am asymptomatic. No fever or dry cough. My pulmonologist told me there's nothing to worry about, but I'm most concern of its size because I know if it burst there will be a possibility that my lung would collapse. Do I have to worry about this? Is there any food that would help shrink its size?
