What is thoracentesis?

ANSWER

If fluid is present in the lining of the lung, removal of the fluid with a needle (called a thoracentesis) may help diagnose cancer as well as improve breathing symptoms. If the fluid tests negative for cancer cells -- which occurs about 60% of the time -- then a procedure known as a video-assisted thoracoscopic surgery (or VATS) may be performed to examine the lining of the lung for tumors and to perform a biopsy.
