A cutting-edge robot-assisted bronchoscope can reach very small tumors growing in the lung's deepest recesses, clinical trial results presented at a European Respiratory Society meeting in Amsterdam suggest. The device uses a specialized CT scanner to find tumors buried deep in hard-to-reach places of the lung, researchers said. A robot helps guide the bronchoscope to those deep places, allowing doctors to take a biopsy and confirm whether tissue is cancerous, researchers said. "The technology
