What is cancer?
Malignant tumor that occurs in epithelial tissue is called cancer. Cancer is a new heterosexual organism, which is automatically proliferated by somatic cells. This new creature is composed of a group of cancer cells that do not develop freely with physiological needs. Cancer cells have no function as normal cells. Because of its rapid and irregular growth, it not only consumes a lot of nutrients, but also destroys the organizational structure and function of normal organs. Tumor cells continue to divide and form new tumor cells, which infiltrate and spread from the primary site to the surrounding tissues. If this diffusion can't be controlled, it will further invade important organs and lead to failure, and eventually lead to death. There are more than 200 kinds of cancer, which can occur in other places except hair and nails. No fewer than 5 million people die of cancer every year in the world.
Carcinogenic factors and countermeasures:
1. Food causes cancer
According to statistics, 50% of women and 30% of men have cancer directly or indirectly.
The ingredients in the diet are related. For example, eating some foods contaminated by sauerkraut or mold for a long time will cause cancer. According to epidemiological data, about 50% of cancers are digestive system and bladder cancer, which is the part where food or waste stays for a long time. This fact also proves that improper diet can cause cancer.
1. 1 lampblack: Cooking lampblack is a serious carcinogen. For housewives, they are the masters of the kitchen.
A large amount of oil fume intake may be one of the reasons for the high incidence of lung cancer in women.
1.2 fried food: fried food will contain aldehydes, ketones and lower fats due to the use of repeatedly heated oil.
Acids, oxides, epoxides, lactones, hot polymers and other carcinogens.
1.3 Smoked food: contains a lot of carcinogens such as benzopyrene and polycyclic aromatic hydrocarbons, and also contains carcinogens.
Qualitative nitrosamine
Smoking and drinking can lead to cancer.
According to the survey, the incidence of lung cancer in heavy smokers is 15~30 times higher than that in non-smokers, and the more you smoke,
The earlier you start smoking, the higher the incidence of lung cancer. Excessive drinking is related to oral cancer, pharyngeal cancer and esophageal cancer. In all regions and countries that drink a lot, the incidence of cancer in these areas is relatively high. The combination of alcohol addiction and smoking can increase carcinogenicity by 15 times.
Everyone should know that smoking is harmful to health, but some people always put it down, which is not only harmful but also selfish. Therefore, to prevent cancer, we must have a healthy lifestyle. Alcohol can be drunk properly and used for health care, but cigarettes must not touch your hands. Even if it is small, it will have a great impact on you and the people around you.
3. Atmospheric carcinogenesis
Urban air is polluted by household and industrial waste gas. At present, there are more than 30 kinds of carcinogens confirmed, of which benzopyrene is the strongest and most representative.
This factor is beyond our control. We should call on the society to strengthen environmental protection, so that people in the whole society can face this factor together.
4. Mental factors lead to cancer
Doctors have found that some adults will feel disappointed and feel inferior because of repeated serious stimuli such as unemployment and divorce.
Emotional depression leads to cancer after 6~ 18 months. Animal experiments have the same result. Clinically, many cancer patients have been traumatized before the onset.
● To prevent cancer, we must have a good attitude and face setbacks calmly. If you are devastated because of a small setback, you may get cancer in the long run.
5. Viruses cause cancer
Viruses that can cause tumors in animals are called tumor viruses. Some human tumors may be related to viruses.
6. Physical carcinogenesis
Ultraviolet (UV) in sunlight can cause squamous cell carcinoma, basal cell carcinoma and malignant melanoma of the skin. Ultraviolet light can make two adjacent pyrimidines in DNA form dimers, which leads to DNA molecular replication errors. In normal people, this kind of DNA damage is repaired by the mechanism of DNA excision and repair. Earlier we mentioned a rare autosomal recessive genetic disease-xeroderma pigmentosum. Because of the congenital lack of enzymes needed to repair DNA, it is impossible to repair DNA damage caused by ultraviolet rays, and the incidence of skin cancer is very high.
● Avoiding ultraviolet rays as much as possible is the best way.
7. Genetic carcinogenesis
The probability of gene carcinogenesis is quite high, and the closer it is, the more dangerous it is. How can we avoid gene carcinogenesis? The occurrence of cancer is closely related to immunity. Therefore, people with family inheritance can avoid cancer as long as they are healthy and have strong immunity. At the same time, regular physical examination every year can lead a better health and life than others.
The occurrence of cancer is closely related to immune function. Studies have shown that even if you have cancer in your family, you will get cancer only after your autoimmune cells are damaged and your immune function is seriously low under the constant stimulation of carcinogenic factors.
Misunderstanding of life:
1, why is it easy to get cancer if you often eat barbecue food? Because when you barbecue food, the fuel will produce a lot of carbon dioxide, sulfur dioxide and a carcinogen called 3,4-styrene-propylene ratio, which will remain on the food, so people are easy to get cancer if they eat too much.
2. Which vegetables are easy to be poisoned: 1). Germinated blue potatoes are poisonous. 2) Fresh daylily (i.e. daylily) is poisonous. 3) Preserve uncooked vegetables. 4) Cooked cabbage and cooked leek overnight will convert nitrate in vegetables into nitrite, which is a strong carcinogen. Boiled cabbage and boiled leek should not be eaten for a long time.
3, children should not eat preserved eggs: preserved eggs are processed with a substance lead oxide, which is toxic and affects intelligence.
4, rotten ginger is not edible: rotten ginger is extremely toxic and can cause liver cell necrosis.
5, soybean oil can not be eaten raw: raw soybean oil contains benzene, which can destroy people's hematopoietic system, so it is not appropriate to use raw soybean oil as cold salad and dumpling stuffing. If soybean oil is boiled in a pot, benzene will volatilize.
6, long boiled water can not be eaten: overnight boiled water and long boiled water, as well as non-daytime boiled water in thermos bottles, all contain a substance called ammonium nitrite, which is a strong carcinogen.
7. Fish and meat are burnt and can't be eaten: fish, meat and other leeks will produce a carcinogen called benzene-propylene ratio when burnt.
8. Newly married men should not eat coke: Coca-Cola can kill sperm in the human body, so men should not eat it if they want to have children after marriage.
9, eating tender fried pork liver is harmful: pork liver is a detoxification organ, and the liver contains a small amount of toxins. If it is not fried thoroughly, it is harmful to eat it.
10, which fruits avoid seafood? Persimmon, grape pomegranate, hawthorn and banana all contain tannic acid. Tannic acid in seafood combines with calcium to form an indigestible substance, which can cause abdominal pain, vomiting, nausea and diarrhea.
1 1, which foods can easily make the skin black? Eating liver, kidney, red beans, black sesame, mullet and strong coffee often makes the skin black.
12, which foods are easy to whiten? Generally, it is yellow-green food such as celery, spinach, onion, apple and radish.
13, what are the four taboos for eating soy milk? 1) Avoid eating brown sugar 2) Avoid washing eggs; 3) avoid unfamiliarity; 4) Avoid using thermos bottles.
14, what are the five taboos for eating milk? 1) Avoid adding brown sugar 2) Avoid freezing 3) Avoid mixing boiled water 4) Avoid taking empty clothes 5) Avoid taking supplements together.
15, oily residue crispy rice is not edible: oily residue crispy rice contains benzene-propylene ratio, which is carcinogenic and not edible.
