Which physical factors have carcinogenic effects and which chemicals cause cancer

What are the physical carcinogenic factors?

Food Carcinogenic Ranking 1Pickled foods: Dimethyl nitrite produced by salted fish can be converted into carcinogen dimethylnitrite amine in the body.

Salted eggs and pickles also contain carcinogens, so they should be eaten as little as possible. 2.Barbecue food:

Roast beef, roast duck, roast mutton, roast goose, roast suckling pig, roast lamb skewers, etc., should not be eaten more because they contain strong carcinogens. 3.Smoked food:

For example, bacon meat, smoked liver, smoked fish, smoked eggs, smoked dried tofu and other carcinogens containing benzopyrene, often eaten are prone to esophageal cancer and stomach cancer. 4.Fried food:

After frying and overburning, the carcinogen polycyclic aromatic hydrocarbons are produced. When coffee is burned, benzopyrene increases 20-fold. Pancakes, stinky tofu, fried taro, fried dough sticks, etc., are mostly oiled that has been repeated many times, and carcinogens can be produced at high temperatures.

5.Mildew substances: rice, wheat, beans, corn, peanuts and other foods are susceptible to moisture mildew, and carcinogenic toxin - aflatoxin will be produced after being contaminated by mold.

6.Overnight ripening of cabbage and sauerkraut: nitrite is produced, which is converted into carcinogenic nitrite amine in the body.

7.Betel nut: Chewing betel nut is a factor in oral cancer. 8.Repeatedly boiled water: Repeatedly boiled water contains nitrite, which forms carcinogenic nitrite amine after entering the human body.

Top 10 carcinogens.

Tamoxifen. Experts are puzzled when it comes to determining the dangers of tamoxifen. Because it is an effective drug to prevent a high incidence of breast cancer in women, and it can prevent the disease**. It was originally thought that this drug was much safer than many chemical** drugs, however, the drug also increased the risk of uterine cancer.

The U.S. Food and Drug Inspection has never determined that the benefits outweigh the harms, but scientists at the U.S. Department of Health and Human Services are concerned that the substance will upset some women who use tamoxifen.

Carcinogens in food mainly include: nitroso compounds, high-fat substances, high-concentration alcohol, etc. Among them, the precursors of nitroso compounds are more abundant in stale foods such as rotten and spoiled foods, and the stomach synthesizes the precursors of nitroso compounds into nitroso compounds when the human body has atrophic gastritis or insufficient gastric acid secretion.

2. Carcinogens in food contamination mainly include:

Agricultural pesticides, household detergents may contain carcinogenic compounds, and food that comes into contact with these can be contaminated.

Some hormonal agents can enter food poultry and livestock through veterinarians** or feed additives, inducing tumors related to the endocrine system.

Some food packaging materials contain a variety of cyclic aromatic hydrocarbons, which are potentially carcinogenic. Such as food packaging bags, wrapping paper, etc.

Carcinogens in the air accumulate in food through soil, water, etc.

3. Additives in food, such as preservatives, food colorings, spices, flavorings and other additives contained in nitrosamines.

4. Food processing and savings are carcinogens, smoked food and pickled food contain a large number of cyclic aromatic hydrocarbon-based carcinogens, moldy rice, corn, beans contained in aflatoxin has a strong carcinogenic effect on humans and animals.

Salted fish. Salted fish produce dimethylnitrite, which in the body can be converted into the carcinogen dimethylnitrite amine. A person who regularly consumes salted fish from birth to 10 years of age is 30 to 40 times more likely to develop nasopharyngeal cancer in the future than a person who does not eat salted fish.

Fish sauce, shrimp paste, salted eggs, pickles, sausages, ham, and smoked pork also contain more nitrite amine carcinogens, so they should be eaten as little as possible.

Barbecue food:Roast beef, roast duck, roast lamb, roast goose, roast pork, etc. Because it contains a strong carcinogen 3,4-benzopyrene, it should not be eaten more.

Smoked food:For example, bacon meat, smoked liver, smoked fish, smoked eggs, smoked dried tofu, etc. also contain benzopyrene carcinogens, and frequent consumption is prone to esophageal cancer and stomach cancer.

Fried food:After frying and overburning, the carcinogen polycyclic aromatic hydrocarbons are produced. When the coffee beans are burned, the benzopyrene content increases by a factor of 20. Pancakes, stinky tofu, fried taro, fried fritters, etc., most of them use oil that has been repeated many times, and a carcinogenic decomposition substance will be produced at high temperatures.

Moldy food. Rice, wheat, beans, corn, peanuts and other foods are susceptible to moisture mildew and mildew, and various carcinogenic toxins will be produced after being contaminated by mold.

Overnight cooked cabbage. Nitrite is produced, which is converted into nitrite amine carcinogens in the body.

Areca catechu. Chewing betel nut is a factor in oral cancer.

Repeatedly boil water. Repeatedly boiled water contains nitrites, which eventually form carcinogenic nitrite.

Undrinkable water and ditch water. Stomach cancer, esophageal cancer, and liver cancer are all related to drinking pond water. People who regularly drink unboiled tap water are 21% more likely to develop bladder cancer and 38% more likely to develop rectal cancer.

Teach you about the 4 common first-order carcinogens.

It is divided into biological, chemical, and physical carcinogens, and there are many carcinogenic substances in these years.

1. Physical carcinogenic factors are mainly:

Direct result of physical factors, such as radiation;

2. Chemical carcinogenic factors are mainly:

Chemicals are indirectly caused, such as nitrites, dioxins.

3. Biological carcinogens are mainly:

The spread of cancer cells is caused by biological agents such as fumaric acid and phenol.

Here are some common chemicals that are thought to be carcinogenic:

1.Benzopyrene: This is a polycyclic aromatic compound that is commonly found in combustibles, grilled meats, etc.

2.Dimethylnitrosamine: This is a nitrosamine compound that is commonly found in grilled meats, among other things.

3.Acrylamide: This is a chemical that is commonly found in plastic products, glues, etc.

4.Titanium Dioxide: This is a common white pigment that is commonly used in sunscreens, cosmetics, etc.

5.Chlorine Brightened Ethylene: This is a kind of chemical aqueous product, which is commonly found in plastic products, chemical production, etc.

6.Formaldehyde: This is a toxic gas that is commonly found in building materials, furniture, cosmetics, etc.
