What is thoracentesis for suspected lung cancer?

ANSWER

Thoracentesis is a test that checks fluid from a sac around your lungs to see if it has cancer cells in it. The lungs are enclosed in a sac. Lung cancer can cause fluid to collect in this sac. This is called pleural effusion. In people who have cancer, this fluid may contain cancer cells.
