WebThese cells that are uncontrollably dividing are also not doing their normal jobs. They are diverting bodily resources and not performing vital functions. For example, if you have tumor in your heart those cancer cells in that tumor are not doing what normal heart cells do, work together to pump blood. The actual immediate cause of death varies. WebCheckpoints can delay cell cycle progression or, in response to irreparable DNA damage, induce cell cycle exit or cell death. Cancer-associated mutations that perturb cell cycle control allow continuous cell division chiefly by compromising the ability of cells to exit the cell cycle. Continuous rounds of division, however, create increased ...

WebCancer cells tend to divide quickly and grow out of control. Radiation therapy kills cancer cells that are dividing, but it also affects dividing cells of normal tissues. The damage to normal cells causes unwanted side effects. Radiation therapy is always a balance between destroying the cancer cells and minimizing damage to the normal cells.
