Cancer cells 'remove blindfold' to spread. Cells are effectively 'blindfolded' as they lose sensitivity to their surroundings early in cancer progression, but scientists used a new method to find some cancer cells are able to switch this sense back on in order to move and spread. In future, these cells could potentially be targeted by treatments before cancer spreads to give patients a better chance of recovery. Source 8w.
