Canadian scientists have made a major discovery about how cancer spreads: tumour cells appear to co-opt normal cells around them, in effect "talking" them into helping the cancer set up shop in other parts of the body.
Working with human breast cancer cells in the lab, Jeff Wrana,
a molecular biologist at the Samuel Lunenfeld Research Institute in Toronto, and colleagues found that tumour cells get sets of instructions in the form of protein "messages" passed between healthy and cancerous cells. Read more here.
