Analysis of Breath Volatile Organic Compounds Using Mass Spectrometry

This study aims to determine whether metabolic changes associated with cancer produce distinct alterations in exhaled breath compared with those of healthy individuals. Breath samples will be analyzed using machine learning techniques to identify volatile organic compound (VOC) patterns and develop diagnostic algorithms capable of detecting multiple types of cancer. The long-term goal is to establish a noninvasive, breath-based screening tool that can facilitate the early detection of various cancers. Additionally, patients and healthy participants who consent to this study may opt in to be contacted in the future to provide additional breath samples.
