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. WebTumor suppressor genes are normal genes that slow down cell division or tell cells to die at the right time (a process known as apoptosis or programmed cell death). When tumor suppressor genes don't work properly, cells can grow out of control, which can lead to cancer. A tumor suppressor gene is like the brake pedal on a car.

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. WebDec 23, 2024 · Chemo works by halting cancer cell division, often by interfering with RNA or DNA synthesis, and shrinking the tumor. The cell cycle goes from a resting phase, to an active phase, then to cell division (called mitosis).
