WebApr 12, 2024 · A carcinogen is a substance that under some condition has the ability to cause cancer. Some cancers are genetic, but the vast majority occur when something goes awry in the normal process of cell division, usually due to damage to DNA caused by exposure to some form of radiation or to certain chemicals. But the devil is in the details. 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.

WebInherited versus acquired gene mutations. Gene variants, including mutations, can be either inherited or acquired. An inherited gene mutation, as the name implies, is inherited from a parent, so it’s present in the very first cell (once the egg cell is fertilized by a sperm cell) that eventually becomes a person. WebCancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor. What is a group of uncontrollable cells called? Cancer begins when genetic ...

WebThis can cause cells that should be resting to divide and grow out of control, which can lead to cancer. Our bodies are made up of trillions of cells grouped to form tissues and organs. Genes inside the nucleus of each cell tell it when to grow, work, divide and die. Normally, our cells follow these instructions and we stay healthy.

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).
