Research reveals cancer pathway to spreading through the body

Scientists show role oxygen plays in cell movement

Cancer cells need oxygen to survive, as do most other life forms, but scientists had never tracked their search for oxygen in their early growth stages until now -- a step toward a deeper understanding of one way cancer spreads that could help treat the disease.

In a paper published online by the Proceedings of the National Academy of Sciences, bioengineers from Johns Hopkins University and the University of Pennsylvania report results of their work showing how sarcoma cells in mice pursue a path toward greater concentrations of oxygen, almost as if they were following a widening trail of breadcrumbs.
