The present invention provides a novel cancer marker for evaluating the onset, the preclinical stage, the clinical stage, or the prognosis of a cancer in a subject, and an evaluation method using the same. A cancer marker containing at least one miRNA selected from hsa-miR-92 and hsa-miR-494 is used as a marker for cancers excluding breast cancer. A method for evaluating the possibility of cancers excluding breast cancer includes the step of detecting the expression level of a cancer marker in a biological sample collected from a subject. In this method, the cancer marker contains at least one miRNA selected from hsa-miR-92 and hsa-miR-494.
