Exhaled Breath Analysis for Cancer Diagnosis and Screening

Cancer is one of the main diseases threatening the human life and health. Early recognition is crucial to increase the survival rate of cancer patients. However, current cancer early diagnosis faces many problems. For example, current early clinical diagnostic techniques have low specificity and sensitivity but need high cost. As the progress for the medicine, the new noninvasive and fast cancer early recognition technique has come out, which is of importance to decrease the death rate. Some research results indicate that the cancer patient could emit some special gas [1], and this provides the possibility to utilize the patient’s emission gas for cancer screening, which is noninvasive, simple and sensitive. This diagnostic method has been adopted by using the trained dogs, which have the sensitive sense of smell [2]. And some research results have proven the possibility to use the dogs to realize the early diagnosis for Crimson Publishers Wings to the Research Mini Review
