In Brief In a new report, scientists detail that have have observed how cancer cells spread from the initial tumor to the bloodstream. This development could allow us to better understand cancer and, thus, how to fight it.

In what could be a major step forward in our understanding of how cancer moves around the body, researchers have observed the spread of cancer cells from the initial tumour to the bloodstream.

The findings suggest that secondary growths called metastases ‘punch’ their way through the walls of small blood vessels by targeting a molecule known as Death Receptor 6 (no, really, that’s what it’s called). This then sets off a self-destruct process in the blood vessels, allowing the cancer to spread.
