Abstract: A cancer screening device includes a cancer screening model generation unit configured to construct, as a cancer screening model, clinical data that is results of cancer screening for a plurality of subjects including cancer patients and healthy subjects, and metabolite exhaustive data that is a result of LC/MS analysis of first urine specimens collected from these subjects and is information related to amounts of a plurality of metabolites in the first urine specimens, a second acquisition unit configured to acquire sample data that is a result of LC/MS analysis of a second urine specimen collected from a second subject who is different from the first subjects, and a screening processing unit configured to estimate the cancer state of the second subject by applying an amount of metabolite in the sample data to the cancer screening model, and an output processing unit configured to output the estimated state of the cancer.
