What is the normal procedure in a lung biopsy?

Procedure specific: There are 3 different ways to do a lung biopsy. Ct guided uses a needle inserted thru the chest while taking ct scan images. Bronchoscopic involves running a flexible tube into the windpipe. Surgical biopsy involves cuts in the chest, either using a rigid tube (vats), or larger incision for an open biopsy.

Several ways: As noted, generally three types of approaches. The radiologist can perform transthoracic needle biopsy. Surgeons and pulmonologists may perform bronchoscopic/transbronchial biopsies. Surgeons may perform surgical biopsies either by vats or open incision. For a surgical biopsy in 2013, it is standard to use a minimally invasive approach and not a thorocotomy.

Depends: It all depends on the method of biopsy. Please provide more detail and I'll be happy to answer.
