More than 50 percent of participants believed that screening lowered the chance of getting lung cancer after the conclusion of the . In qualitative analyses, participants were not aware of the purpose of lung cancer screening; wanted to know more about benefits and harms; felt that physicians needed to communicate more effectively; found decision aids helpful and influential for making decisions; and wanted personalized and tailored discussions. Participants were surprised that the magnitude of their lung cancer risk and benefits of screening were lower than expected.
