- Interventional
- Cardiopulmonary stress testing
-
Endobronchial ultrasound (EBUS)
- Exhaled nitrous oxide testing
- Pleural biopsy
- Thoracentesis
- Transbronchial needle aspiration
Biopsy techniques can now avoid conventional surgery by using minimally invasive procedures like endobronchial ultrasound (EBUS) to diagnose lung cancer and other chest diseases. A minimally invasive approach allows physicians to perform a transbronchial needle aspiration to obtain tissue and/or fluid samples from the lungs and surrounding lymph nodes. The procedure is less invasive and the recovery time shorter than conventional surgery.
