A breakthrough in cell research may pave the way for treatments which stop cancer spreading through the body.
Scientists at British universities have worked out for the first time how cells are able to migrate from organ to organ.
The new research, spearheaded by biologists at University College London, could transform the way cancer is treated.
Crucially, the discovery has enabled scientists to work out how to block the movement of cells.
It means that aggressive cancer, which can quickly advance away from a primary tumour, might in the future be effectively frozen and isolated as soon as it is detected.
