The USPSTF does not address who will evaluate people who are interested in or should consider CT screening for lung cancer. Traditionally, screening has been the task of primary care physicians—but how well will this work? Lung cancer differs from other types of cancer: Screening is new, the prognosis is particularly grim compared with other cancer types for which screening is recommended, and the risk is highly variable and complex. Do primary care physicians have the knowledge, skills, and time to advise patients on lung cancer screening? If not, how do we provide them with the knowledge and tools they need? Are there other providers who are up to the task (for example, radiologists, pulmonologists, or nurse practitioners)? We need to develop this workforce to optimally implement lung cancer screening.
