The wide clinical experience of the contributing authors has ena- bled every aspect of this disease to be considered, with emphasis being placed on diagnostic techniques such as CT scanning and fine needle transpleural biopsy, as well as on the latest method of treatment by lasers. Bronchial carcinoma remains the major cause of cancer death in the United Kingdom, accounting for 60Jo of all deaths. While the incidence has decreased slightly in the male population, there has been an equivalent increase in the female population.
