WebWhen a cell’s DNA is damaged, it will typically detect the damage and try to repair it. If the damage is beyond repair, the cell will normally send itself into apoptosis, ensuring that it will not pass on its damaged DNA. When cells have DNA damage but fail to undergo apoptosis, they may be on the road to cancer.
