In the present invention, a salivary biomarker for cancer is characterized in being any low-molecular-weight compound that is a metabolite of a saliva sample, or a combination of such compounds. The salivary biomarker for cancer can be, for example, a combination of creatinine, N1-acetylspermidine, alpha-aminoadipate, N-acetylneuraminate, and 1,3-diaminopropane. Due to this configuration, the early detection of pancreatic cancer, breast cancer, oral cancer, and the like is possible in a healthy subject, even with saliva having large concentration fluctuations. |
