Timing could matter to how responsive cancer cells are to treatment
DNA damage occurs routinely within your cells due to sun exposure, smoking and sometimes during the normal process of making new DNA. Fortunately, there are "checkpoints" in-place within cells to stop them from making more DNA and dividing before the damaged DNA is repaired. But in the case of cancer, cells may ignore these checkpoints, and go on to divide with damaged … [Read more...]
