Hello, my dad is hospitalized since a week for massive left pleural effusion with lung collapse of lung. He has undergone test for cytology & meligaine cell test ,Kidney ,Lever ,pneumonia & tuberculosis which are negative (Reports done from SRL Diagnostics). We are awaiting a second round test from Hospital for the fluid from Lungs removed for a confirm clarity. In about 4 days they have removed about 4 Litres of fluid which was reddish in colour. He is out of ICU and has been complaining for left hand pain & cough for last 7 days since hospitalized. We will get the reports from TATA tomorrow. But am concerned as the reasons for the fluid in lungs is not known by the doctors. We are being told he has lump on both side of the lungs. Could I know what are the health issues with my dad.
