To the Editor:Cancer is the leading cause of death in China.[1]With rapid economic development,18F-fluorodeoxyglucose(FDG)positron emission tomography(PET)/computed tomography(CT)for screening cancer in asymptomatic patients is gaining popularity in China.PET/CT is a type of molecular imaging technology,which uses a specific tracer for localization and quantification of the disease at a molecular level.[2]However,the utility of such screening is still controversial.[3]Based on the past clinical experience,the previous physical examination protocol has been optimized,and a classical physical examination protocol has been set up at the author’s study center.So far,there is no evidence to know which approach was better for cancer screening in asymptomatic individuals.
