Discovery of the trick used by tumours to travel through the body may hold the key to stopping cancer from spreading. Cancer's ability to colonise other organs is what makes the disease so lethal. Instead of spreading accidentally when cancerous cells break off a primary tumour and enter the bloodstream, the research team found the primary tumour first sent out blood-borne emissary substances. This advance team sets up home at another site. Only then does the tumour send cancer cells through the bloodstream to settle at the secondary site.
