The most important biological factors are viral infection. Especially those who have been in radiation work for a long time are more likely to cause the transformation of cells in the body, which may eventually induce cancer.

01

Why is cancer becoming more and more "rampant"?

1. The most important factor is viral infection. Modern research believes that certain viral infections are closely related to cancer, such as EB virus infection and nasopharyngeal carcinoma ; human papillomavirus infections and cervical cancer , etc.

2. Physical factors. For example, ionizing radiation can cause many tumors. Especially those who have been in radiation work for a long time are more likely to cause the transformation of cells in the body, which may eventually induce cancer.

3. Chemical factors, that is, chemical substances and chemical toxic substances will cause certain malignant tumors, such as xylene , formaldehyde , which will cause lung cancer, leukemia, etc.

4. Environmental factors. For example, air pollution and dust pollution in the workplace can induce many cancers. Nowadays, people's living environment has suffered huge damage, which will increase the chance of lung cancer and other things.

5. Psychological factors. Patients who have a long-term unpleasant mood and are emotionally depressed are prone to malignant tumors such as breast cancer and , lung cancer. Excessive stress can lead to reduced immunity and bacteria and viruses attack the body.

6. Genetic factors. Patients with a family history of tumors are more susceptible to certain tumors, and the risk of tumor development is significantly higher than those without a family history.

What foods are not recommended to eat?

The occurrence of cancer itself is related to many factors, so diet is naturally indispensable. As the saying goes: disease enters from the mouth. If you eat foods with toxins frequently, it will lead to physical health damage and increase the risk of multiple diseases, which may eventually induce cancer.

- High-temperature barbecue

Barbecue is a relatively popular meat food. Although eating barbecue in small amounts does not have much impact, if you eat barbecue frequently, especially high-temperature barbecue, it will increase the content of harmful substances in the body and cause digestive tract cancer. When barbecue with

, if the temperature exceeds 400℃, a carcinogen called heterocyclic amine will be produced. Everyone thinks that they have never seen heterocyclic amines. When eating barbecue, the black substance that is scorched on it is heterocyclic amines.

When grilling food at high temperature, grease on the meat will drip in. If charcoal does not burn , it will produce carcinogen called polycyclic square scarf. If it is smoked by this smoke, it will also increase the risk of respiratory diseases.

study found that two major conditions are required to produce carcinogen benzopyrene , namely, the temperature exceeds 300℃ and fat. Obviously, whether it is charcoal or electric grilling, the temperature will definitely exceed 300℃. Therefore, it is recommended that you eat less high-temperature barbecue.

- Moldy food

Speaking of foods that "carry toxins", moldy and spoiled foods are indispensable. Nowadays, living conditions are generally improved, but some middle-aged and elderly friends are still reluctant to leave the moldy food at home, but choose to deal with the moldy part and continue to eat the remaining food.

The main "killer" of mold in food is mold, mold belongs to fungi, and the toxic substance it produces is called mycotoxin . The well-known aflatoxin is actually a type of mycotoxin, and it is also the most toxic mycotoxin.

According to relevant research, it is found that the toxicity of aflatoxin is 10 times that of potassium cyanide and 68 times that of arsenic. It is very toxic, especially causing strong damage to liver cells. One milligram of aflatoxin may cause cancer in the body.

It is very difficult to destroy aflatoxin. The temperature must reach above 280℃. It is difficult for ordinary families to meet the standards. If you just cut off the moldy part and continue to eat the rest after cleaning it, it will still increase the chance of mold infection.

—— betel nut

betel nut is a very familiar refreshing food. Because betel nut contains arecaline and ephedrine, it creates pleasure, so it has a certain degree of addiction, and betel nut causes cancer has been widely recognized.

As early as 2003, World Health Organization listed betel nut as a first-class carcinogen. The carcinogenic mechanisms of betel nut can be mainly divided into two categories: physical stimulation and chemical destruction.

Friends who chew betel nuts will know that the umami flavor of betel nuts is very rough. Long-term chewing betel nuts will damage the oral mucosa and teeth. Betel nut contains carcinogenic ingredients, such as arecanine betel nutine, etc., which cause irritation to the oral mucosa and cause oral cancer.

Chewing betel nut to destroy oral tissue, then new cells will be produced for repair. Gene mutations may occur in each repair process, which will eventually gradually increase the chance of cancer.

- Pickled food

Now it is winter, and many families have already brought pickled pickles to the dining table. Whether it is pickled pickles, pickled bacon, pickled salted duck eggs, etc., it is not conducive to health.

foods will produce nitrite during pickling. Although nitrite is not carcinogenic, nitrosamines will form when they enter the body when combined with gastric acid , which is compulsory cancer.

When people pickle food, in order to extend the shelf life, they add more salt, which will naturally cause damage to the gastric mucosa and even increase the chance of infection with Helicobacter pylori, which eventually leads to gastric cancer .

- Processed meat

Processed meat foods actually belong to foods with "own toxins", which makes many people feel incredible. Processed meat mainly includes bacon, ham sausage, bacon, smoked barbecue, beef jerky, hot dog , etc.

In 2017, the World Health Organization International Cancer Research Institute listed processed meat as a first-class carcinogen because such foods are more likely to cause damage to the body.

During the production process, the preservative nitrite is added or nitrite is produced. Long-term intake will cause serious damage to the body.

Eating too much processed meat food will also cause abnormal functions of various organs and may increase the chance of cancer. Therefore, any processed meat food needs to be included in the blacklist as soon as possible.

trans fatty acids

Speaking of trans fatty acids, many people feel confused. Trans fatty acids are just a general term, including many types, such as hydrogenated vegetable oil , shortening , margarine, vegetable fat powder , generation cocoa butter , refined vegetable oil, margarine, etc.

Eating foods with excessive trans fatty acids for a long time will lead to excessive obesity in the body, increase blood concentration, and even increase the risk of cerebral infarction and coronary heart disease , and even cause premature puberty in children.

Trans fatty acids themselves are foods with their own toxins, because eating too much will indeed cause damage to the body, especially increasing the chance of cardiovascular disease and may also increase the risk of cancer, so it is recommended that you eat less.

—Alcohol beverages

Alcohol beverages have long been listed as first-class carcinogens. About 10% of alcoholic beverages are metabolized by the gastrointestinal tract; more than 90% are metabolized by the liver, so long-term drinking is more likely to increase the chance of liver cancer.

The British magazine "Addicted" pointed out that alcohol can cause cancer and is related to at least 7 types of cancer. Long-term drinking can lead to damage to liver function and may even induce liver cancer risk.

Alcohol drinks themselves are foods that have "own toxins". If the consequences of your frequent intake of the body are unimaginable, I hope everyone can quit drinking as soon as possible. Of course, drinks containing alcohol cannot be drunk.

03

Early symptoms of cancer, it is recommended to know early!

① Any part of the body, such as breast , neck or abdomen, especially those that are gradually enlarged.

② There are no ulcers caused by trauma in any part of the body, such as the tongue, cheek mucosa, skin, etc., especially for a long time.

③ Women over middle-aged have irregular vaginal bleeding or abnormal secretions.

④After eating, stuffy, burning pain, foreign body sensation or progressively worsen swallowing.

⑤ Dry cough or blood in the sputum that has not been treated for a long time.

⑥ Those with long-term indigestion, progressive appetite loss, weight loss, and no clear cause was found.

Stool habits change or Stool blood .

⑧Narrow congestion, epistaxis, unilateral headache or dipsia .

Black mole suddenly enlarges or has ulceration, bleeding, and original hair loss.

⑩ Painless hematuria.

extension - What tests are done when screening for cancer?

If you want to screen for cancer, you should first do a tumor-related marker examination. Patients can check the commonly used tumor marker through blood collection, such as carcinoembryonic antigen , carboembryonic antigen 199, carboe antigen 125, carboe antigen 153, alpha-fetoprotein, squamous cell carcinoma antigen, etc. Male patients can also check prostate-specific antigen .

In addition to collecting blood as tumor markers, screening for cancer also requires CT and B ultrasound in the corresponding part. For example, patients can do chest CT, head CT, liver CT, or B-ultrasound examination, neck thyroid , gastroscopy , colonoscopy , female patients can also do breast ultrasound, gynecological , etc. Men also need to do prostate B-ultrasound, CT, and MRI.

Cancer screening is very important. It can detect physical lesions in a timely manner and help reduce the risk of disease. Therefore, high-risk people must pay attention to it and conduct regular cancer screening, so that they can help reduce the risk of physical lesions.
