Potential of breath analysis as a complementary diagnostic tool in cancer. This is an illustration of the potential of breath analysis and its implementation as a dependent or complementary test that could be beneficial for cancer management. Noninvasive and easy to perform, volatolome assessment could promote early and differential diagnosis, cancer classification, staging and monitoring. However, extensive research and development are required to increase both clinical performance and integration into real clinical-world conditions. PET: positron emission tomography; CT: computed tomography; LDCT: low-dose CT; MRI: magnetic resonance imaging; HNC: head and neck cancer; SCLC: small cell lung cancer; NSCLC: nonsmall cell lung cancer; EGFR: epidermal growth factor receptor.
