Plureal mass in left lung 5 cm. i did biobsy and pet scan and no evidence of cancer.what is that.is it fungus or worm or what i should do..wheezing?

Pulmonologist: The possibility of a mass requires more diagnostics, with your symptoms it is possible its pnemonia, much less concerning than a cancer mid-lung. Scanning can help, but a pulmonologist can decide the right test to reduce fear and misdiagnosis. Hopefully you are using a broncholdilator among the medications you are using. The pulmonologist can direct specific therapy and help treat what you have
