<s>[INST] I have had fluid removed from my right lung within the past 6 months. Now I can tell I am getting some in the other lung. This has been confirmed by my family physician. Is this dangerous? How often can it be removed? Is there a procedure other than a needle that can take it away? Why does it happen? Can I prevent it? [/INST] Hello,Usually, when the pleural fluid repeats, we do pleurodesis however, it depends on the cause of the fluid. Hope I have answered your query. Let me know if I can assist you further.Regards,      Dr. Jnikolla </s>
