Cancer is a disease of enhanced proliferation and cell survival. DNA repair mechanisms are normally important for cell survival. When a cell senses DNA damage, the cell cycle is inhibited until the damage is fixed. Given the importance of DNA repair mechanisms, how can their failure lead to the production of cancer cells with a competitive advantage over normal cells?
