Can Breast Cancer Be Cured Fully? To me, “Cured Fully” means that it never starts in the first place. And the answer to that is NO. Normally, a normal breast cell follows it’s direction from its own DNA and replicates to form a new ‘daughter’ cell exactly like itself, then dies and allows the ‘daughter’ to take its place. Eventually (3 to 6 months in the breast) the “daughter” will get the same signal and it will form its own “daughter” cell exactly like itself and then die.
