The present invention relates to a cancer diagnosis method for detecting a volatile organic compound specifically contained in an exhalation of a cancer patient and, more particularly, to a method for providing information on cancer diagnosis including a step for measuring the presence and absence of materials having a molecular weight of (i) 69, (ii) 131, and (iii) 181, which are ionized fragments of a cancer specific VOC, from the respiratory gas collected from a suspected cancer patient. According to the present invention, an early diagnosis of cancer at a high degree of sensitivity can be made non-invasively from the exhalation of a cancer patient. Thus, the cancer diagnosis method of the present invention is more economical and expedient than conventional cancer diagnosis methods. |
