Is it true that cancer cells emit specific volatile organic compounds as chemical signatures?

Yes. Multiple clinical and in vitro studies demonstrate that cancer cells and tumors emit specific volatile organic compounds that serve as detectable chemical signatures for non-invasive diagnostics.

The analysis

The claim states that cancer cells emit specific volatile organic compounds as chemical signatures. Papers [0], [1], [2], [3], [4], [5], and [8] all provide strong empirical or review evidence that cancer cells, tissues, and tumors produce distinct volatile organic compounds that can be detected in vitro or via breath analysis to identify various cancers. There are no refuting papers.
