Dr. Abbie Begnaud, a lung cancer expert at the University of Minnesota, discusses who should have low-dose CT lung cancer screening and how often. She explains that a low-dose CT of the chest is not for everyone but rather reserved for people who have a high risk of lung cancer, in particular a history of cigarette smoking. She recommends that people who do get screened with a low-dose CT should do so annually to improve survival through early detection.
