Metastasizing and Non-Metastasizing Tumors Likely Evolve from DNA Phenotypes via Independent Pathways

We have recently discovered, using statistical models of Fourier transform-infrared spectra, two distinct cancer DNA phenotypes in histologically normal tissues surrounding non-metastasizing primary tumors and tumors with evidence of distant metastases. Structural comparisons of the DNA from these tumor types imply that each evolves via a separate pathway from DNA phenotypes originating in progenitor cells. These findings challenge the widely-held concept of metastasis.
