If your doctor has discovered a mass on a chest x-ray or on a CT scan, then you may need a CT guided lung biopsy. Some lung nodules are benign but some may be malignant. The characteristics of the mass can only be determined after a biopsy.
Thanks to revolutionary new technology, a CT scan can identify the location of the mass and a biopsy can easily be performed with a needle. The test is usually performed in a radiology department. The procedure is performed by a radiology specialist. CT guided biopsy of the lung is not only cheaper and safer than surgery, but is a much more convenient procedure.
