Reoccurring pleural effusion. 800 mlFluid drained left lung twice in 5 weeks. White count up. Wheezing, short breath. No cancer. Liver good. Heart good. Lung part collapsed. No fever no cough.?

Effusion. I believe the next step should be a pleural biopsy which can be diagnostic of entities such as tb,asbestosis or mesothelioma,lymphoma for example. Knowing whether the effusion is an exudate or transudate is helpful. In my opinion A pulmonologist or thoracic surgeon should be consulted in such cases.
