- A carcinogen is a substance that is capable of causing cancer. Carcinogens do this by increasing the rate of cellular division, which increases the probability of abnormal DNA synthesis.There are many known carcinogens. Some of these include tobacco, pesticides, and asbestos.esson Summary. A carcinogen is a substance that is capable of causing cancer. Carcinogens do this by increasing the rate of cellular division, which increases the probability of abnormal DNA synthesis. There are many known carcinogens. Some of these include tobacco, pesticides, and asbestos.

- 1. The ingestion of numerous acid forming foods, fatty foods, refined foods, carcinogenic substances such as nitrates (cold cuts, hot dogs, sausages), aspartame, and chemically treated foods. X-ray and airport body scanners also contribute. 2. Constipation is increased. 3. An increase of acidity in the blood.

- Exposure to several carcinogens at once may result in cancer rates higher than would be expected by adding the risks from each carcinogen separately. This is known as a synergistic effect. For example, both cigarette smoking and exposure to asbestos have been show to cause cancer.

Carcinogen Carcinogens cause cancer by producing changes (or mutations) in the genetic material, or DNA, of a cell. These mutations result in uncontrolled cell division. A cancer-causing substance can alter the DNA of a cell directly or it can react with other chemicals in the body to form substances that cause gene mutations.

Biology - Cancer Exposure to pollutants such as metals, dust, chemicals, or pesticides can increase the risk of cancer. At least four types of DNA viruses, hepatitis B and C viruses, Epstein-Barr virus, and human papillomavirus, are directly believed to cause human cancers. Nutrition is emerging as a way to help prevent cancer.

Carcinogen Types, Testing, and Examples Determining if a Substance or Exposure is a Carcinogen/Testing for Carcinogens. It is not always easy to determine if a substance or an exposure is a carcinogen. A good example of this is smoking. It took many years of research and millions of dollars to determine the relationship of smoking to lung cancer.

Cancer Agents that may cause cancer include: Chemical carcinogens. Several chemicals and environmental toxins are responsible for changes in normal cellular DNA. Substances that cause DNA mutations are known as mutagens, and mutagens that cause cancers are known as carcinogens. Particular substances have been linked to specific types of cancer. Tobacco smoking is associated with many forms of cancer, and causes 90% of lung cancer.

LIST OF CARCINOGENS (Revised & Detailed List) Alcohol is used frequently as a solvent and is also found in beverages and medicine. As an ingredient in ingestible products, alcohol may cause body tissues to be more vulnerable to carcinogens. Mouthwashes with an alcohol content of 25% or more have been implicated in oral cancers. Alpha Hydroxy Acid: skin irritant.

- A carcinogen is any substance, radionuclide, or radiation that is an agent directly involved in causing cancer.This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes.o-carcinogens are chemicals that do not necessarily cause cancer on their own, but promote the activity of other carcinogens in causing cancer. After the carcinogen enters the body, the body makes an attempt to eliminate it through a process called biotransformation.

Carcinogen Types, Testing, and Examples Carcinogens do not cause cancer in everyone who is exposed; the ability of a carcinogen to cause cancer depends on many factors, including the amount of exposure, the length of exposure, the health of the individual, and other factors in the person's life that either raise or lower the risk of cancer.

A Rough Guide to the IARCâs Carcinogen Classifications A Rough Guide to the IARC’s Carcinogen Classifications. Today’s big news has been the story that the World Health Organisation (WHO) has classified processed meat (including bacon, ham, and salami) as a Group 1 carcinogen. This places it in the same group as smoking, which has led to a number of headlines claiming that it means the risk from the two is the same.
