Patients for this study will be identified in the Radiation Oncology department as being planned to receive SBRT for their lung cancer. All eligibility will be reviewed. Once a patient is deemed eligible and reviewed and signed the informed consent, he/she will be asked to complete the smoking questionnaire available on the state of Michigan (MI) Quitline. If a patient is deemed eligible and decline to enroll, they will be asked to voluntarily complete the American Heart Association (AHA) Smoking Quiz as an eligible patient exit form. Following their completion of this quiz, they will be asked again if they are certain of their desire to decline the study. All enrolled patients will also complete the AHA smoking quiz.
