<s>[INST] Hi Doctor,My name is Kavitha and i am writing for my husband. He is 29, has come problems in the lungs. Some fluid is accumulated in the lungs and there is a mass of 7.2cm, all the test results says there is no lungs cancer cells, or tb. Can any one please help me out with this. Many Thanks for your help in advance. Kavitha [/INST] Hello dear Kavita, warm welcome to Chat Doctor.come have evaluated your query for your husband in details .* There must be definite diagnosis for the management.* The type of pathology is mandatory to guide further.  I recommend lung biopsy from the mass for deciding further plan of action.* It would be of great help if you attach his reports of lab, x-ray , Ct scan herewith so that I can guide you still more accurately. Hope this will help you for sure . Wishing him fine recovery. Welcome for any further guidance. Regards . </s>
