This biopsy technique involves making small incisions in the chest to insert a thoracoscope \u2014 a thin tube equipped with a camera and light \u2014 into the pleura (lining of the lungs). Doctors can then remove a biopsy sample<\/a> and study it under a microscope to determine if you have cancer.<\/p>\n “Even though it’s a surgical procedure, it requires only a one-centimeter incision, and it will provide adequate tissue to lead to that diagnosis more rapidly so patients can be treated adequately.”<\/p>\n![\"\"](\"\/wp-content\/uploads\/2021\/04\/Robert-Taylor-Ripley-MD-300x300-1.png\")
