Breath Volatile Organic Compounds (VOC) Analysis Using Proton Transfer Reaction Mass Spectrometry (PTR-MS)

The purpose of this clinical trial is to evaluate whether volatile organic compound (VOC) signatures detected in the breath of patients with cancer can serve as a potential screening tool for the early detection of cancer.

Inclusion: Age ≥ 18 at the time of consent. Male and female patients to be tested; Capable of understanding written and/or spoken English language; Able to provide informed consent; Cancer of any type; Newly diagnosed cancer and untreated or established diagnosis of cancer.
