Pleural effusion, also called âwater on the lung,â is an excessive buildup of fluid between your lungs and chest cavity. Thereâs always a small amount of liquid inside your lungs.This fluid works to coat the membranes (pleura) that line the outside of your lungs and lubricate the chest cavity to aid in breathing.he pleura creates too much fluid when itâs irritated or infected. This fluid accumulates in the chest cavity outside the lung, causing whatâs known as pleural effusion. Certain types of cancer, such as lung, breast, and ovarian cancers, can cause pleural effusions. Lymphoma and mesothelioma can cause them too.
The fluid accumulation may be inside the lung (pulmonary edema) or outside the lung (pleural effusion), in the space between the lung and chest wall. The term âfluid in the lungsâ is also used to refer to mucus inside the lungs. Mucus or phlegm is a thick, sticky secretion while âlung waterâ is a thin fluid.Other fluid accumulation may be the result of blood or pus. The lungs are located in the thorax (chest) and lies on either side of the heart.reatment is dependent on the cause of the fluid in the lungs. Some of the treatment options may include 1  : Antibiotics, antivirals or antifungals may be necessary in the case of an infection. 2  Diuretics assist with passing out additional fluid but should be used cautiously in the case of cardiac diseases.
