Cancer cells send out advance party
— how cancer spreads

Cancer cell

Scientists have discovered how cancer spreads from a primary site to other places in the body. Instead of a cell just breaking off from a tumour and travelling through the bloodstream to another organ where it forms a secondary tumour, or metastasis, the cancer sends out envoys to prepare the new site.

If these envoys can be prevented from preparing new sites, then the spread of cancer could be reduced or prevented.
