 The objectives of this study are to develop and implement a LDCT screening approach for lung cancer and mesothelioma in asbestos-exposed workers in Alberta; to determine participants motivation and expectations associated with a screening program, their satisfaction with the program, and the psychosocial consequences of the screening program; to determine the accuracy of a lung cancer risk prediction model modified to include asbestos exposure; and to determine the 3-year clinical incidence of lung cancer in asbestos-exposed individuals interested in lung cancer screening but who do not meet minimal risk threshold.
