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. 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.

WebUncontrolled Cell Divisions Create Tumors including Cancers. Tumors, including cancers, are caused by abnormal cells that multiply continuously. If the abnormal cells continue to divide unstopped, they can damage the tissues around them, spread to other parts of the body ( malignancy ), and even result in death. WebDec 1, 1990 · Molecular genetic analysis of human cancers has shown that tumor cells contain multiple genetic defects including mutations, translocations, and amplifications of oncogenes and are reduced to homozygosity for putative tumor suppressor genes; these phenomena all require cell division for their occurrence and fixation.

WebApr 18, 2024 · It is believed that cancer occurs because a genetic mutation can trigger the production of an enzyme, known as telomerase, which prevents telomeres from shortening. 7 While every cell in the body has the genetic coding to produce telomerase, only certain cells actually need it.
