What causes a oncogene to form that changes normal cells into cancerous cells?

Cancer-causing agents that transform normal cells into cancer cells are known as carcinogens. Carcinogens are substances or exposures that have the potential to cause cancer by damaging the DNA within cells, leading to uncontrolled cell growth and proliferation. There are various types of carcinogens, and they can be found in both natural and human-made environments. Here are some common examples of carcinogens:
Chemical Carcinogens: Certain chemicals, both naturally occurring and synthetic, have been linked to cancer development. Examples include tobacco smoke, asbestos, benzene, formaldehyde, and some industrial chemicals.
Radiation: Ionizing radiation, such as ultraviolet (UV) radiation from the sun or tanning beds, X-rays, and gamma rays, can damage DNA and increase the risk of cancer. Non-ionizing radiation, like radiofrequency radiation from cell phones, is considered a possible carcinogen but requires further study.
Infectious Agents: Some viruses and bacteria can cause chronic infections that lead to an increased risk of cancer. Examples include human papillomavirus (HPV) linked to Cervical cancer, hepatitis B and C viruses associated with liver cancer, and Helicobacter pylori linked to stomach cancer.
Lifestyle Factors: Certain lifestyle habits can contribute to cancer development. Tobacco use, excessive alcohol consumption, an unhealthy diet, lack of physical activity, and obesity are all lifestyle factors that can increase cancer risk.
Hormones: Hormones play a role in cell growth and differentiation, and certain hormonal imbalances or exposures can increase cancer risk. For example, long-term use of hormone replacement therapy (HRT) in women may be associated with an increased risk of certain cancers.
Genetic Mutations: Inherited genetic mutations can increase the risk of developing certain types of cancer. These mutations can be present from birth or acquired over a person's lifetime due to various factors, including exposure to carcinogens.

How does a proto-oncogene differ from an oncogene?
Compare with a virus: dormant to active, potential to kinetic, potent(ial) to actual. The proto-oncogene may become a cancer-causing oncogene only under very specific conditions and may, under other conditions, just as well lay dormant.
What effect does oncogenes have on cells?
Cells with an oncogene become over-stimulated to divide more often than normal. The chances of cancer developing are increased if a mutation to a tumor-suppressor gene also occurs. As an oncogene is a cancer-causing gene
What are dividing normal human cells called?
Healthy, non-cancerous cells.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
What motion causes normal fault?
a pulling motion causes a normal fault
What is a mutation that forms an oncogene that changes normal cells into cancerous cells?
to a gene
What is pro- oncogene?
An oncogene is a gene, when mutated or expressed at high levels it helps turn a normal cell into a tumor cell.
Will normal or cancerous cells have a higher growth rate?
the cancerous cells

What is it called when normal body cells turn cancerous?
Carcino-Genesis.
The process in which a normal cell become a cancerous cell is called what?
Dysplasia
What goes wrong with a normal cell when it becomes cancerous?
A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.

Is a medium slize hard lump on the back of a dog normal?
No, it is not normal and the dog should be checked by a veterinarian in case it is a cancerous tumor.
What causes snot like vaginal mucus?
Ovulation can make it thicker if that is what you mean. It's normal. The discharge changes during your cycle.
