<s>[INST] I have been having issues with my right lung filling up with fluid 3 weeks ago I had 2liters removed and it is half full again the Dr is sending men to heart Dr could it be chef with just one lung filling up I am only 44 but I also ha vaginal cancer too [/INST] Thanks for your question on Chat Doctor. In my opinion you should first consult pulmonologist and get done CT THORAX and repeat pleural fluid aspiration and its examination. Since you had vaginal cancer in the past, there is high possibility of malignant spread in pleura. And recurrent pleural effusion even after tapping is the feature of malignant effusion. So we need to rule out malignancy first. So get done CT THORAX.  As this will give you better idea of pleural spread. Get done pleural fluid cytology to rule out malignancy. </s>
