Anything around us that has something to do with cancer is terrifying. In fact, cancer is not only related to its own factors, but also has a close relationship with the external environment. Today we will take a look at some common carcinogens in our daily life.
5 common carcinogens in life are hidden in these items
1, daily contact
For example, acetaldehyde related to alcohol is a substance produced by the metabolism of ethanol in the human body. It can cause DNA damage or double-strand breaks in cells and cause cancer.Ethanol can also generate a large number of oxygen free radicals through enzymes, which can easily make liver cells cancerous.
In addition, wine and alcoholic beverages may Carcinogens that produce polycyclic aromatic hydrocarbonsAbstain from alcohol and alcoholic beverages to prevent harm from these carcinogens.
Cigarettes contain A large number of phenolic compounds, polycyclic aromatic hydrocarbons such as benzopyrene, and carcinogens such as formaldehyde, including second-hand smoke and smokeless tobacco, also contain carcinogens. If you want to prevent these carcinogens, the best way is to not smoke and stay away from second-hand smoke.
Cured meatcontains high levels of nitrite and phosphate;smoked meat contains polycyclic aromatic hydrocarbon compounds such as benzopyrene. In addition, Chinese-style salted fish produces a large amount of nitrite during pickling, which may be related to the occurrence of nasopharyngeal cancer. Therefore, pay attention to your diet, and it is best not to consume too much processed meat.
Outdoor Air Pollution:
Air pollution, such asdiesel engine exhaust, increases the risk of lung and bladder cancer, such as in outdoor air pollution span>Inhalable particulate matter PM2.5, etc., is very harmful to health and easily increases the risk of cancer.
Wearing a mask when going out can reduce the harm of outdoor air pollution. It is best not to exercise on the side of the road.
The formaldehyde we come into contact with in our lives mainly comes from man-made panels in newly renovated houses, formaldehyde may cause childhood leukemia, nasopharyngeal Cancer, myeloid leukemia, fetal malformations, etc. If it is a newly renovated house, it is best not to move in immediately, and it needs to be ventilated for more than 5-6 months before moving in.
Hepatitis B virus:Hepatitis B virus may cause loss of DNA front or DNA rearrangement Degradability of substances.
Hepatitis C virus:There is a strong link between the viral core protein and liver cancer relation.
Human immunodeficiency virus type I: also known as HIV, can synthesize DNA and integrate into host cells When the cellular immunity is destroyed and the immune surveillance function is lost, the cells are more likely to become cancerous.
HIV is mainly transmitted through sex, blood, and mother-to-child transmission, so you should always pay attention to self-care and avoid high-risk sexual behaviors, Abuse of blood products, etc.
Human papillomavirus:A DNA virus that can be divided into high-risk and Low-risk types, of which high-risk types 18 and 16 are the main types of cervical cancer, regular physical examination and HPV vaccination can effectively prevent this risk.
Helicobacter pylori:Many studies have shown that infection with Helicobacter pylori can significantly increase the risk of gastric cancer, and the number of gastric cancer caused by Helicobacter pylori has also been found mechanism. Helicobacter pylori can be transmitted by mouth-to-mouth and fecal-oral, so pay attention to personal hygiene, wash hands frequently, and use public chopsticks when eating.
Aflatoxins:Aflatoxins are mainly derived from Moldy corn, wheat, peanuts, rice, soybeans and other grains, as well as oil and nut products, are the main cause of liver cancer, colon cancer, stomach cancer and other diseases factor. What we should do is refuse to eat moldy and spoiled food, and regularly replace kitchen utensils such as cutting boards and chopsticks.
< span>Solar radiation:For exampleexcessive sun exposurecan cause UV rays from the sun to damage skin cells DNA, thereby causing skin cancer, it is best to apply sunscreen when you go out, and do not expose yourself to the sun.
Ionizing radiation:is the ionizing effect of ionizing radiation mainly include alpha rays, beta rays, neutron fluxes, proton fluxes, X rays, gamma rays, etc., which can induce different types of radiation. DNA damage and cause cancer.
Estrogen:Estrogen therapy, such as during menopause, may increase the risk of developing cancers such as endometrial and breast cancer. Therefore, we cannot supplement estrogen at will, and for menopausal women, it also needs to be supplemented under the guidance of a doctor.
Aristolochic acid:Research has found that aristolochic acid can pass Gene mutation causes liver cancer. Common plants containing aristolochic acid include aristolochic acid, aristolochia, guanofangji, angelica, bone-seeking wind, asarum, guanmutong, etc. . Therefore, Chinese medicines and proprietary Chinese medicines should not be abused, and medication should be prescribed by a doctor.
5. Occupational exposure
Painters, painters, plasterers, etc.:Paints and other coatings and organic solvents contain formaldehyde and benzene, etc.; pigments contain lead, cadmium, chromium, mercury And other heavy metals, long-term exposure to these substances can increase the risk of cancer. For people in this type of occupation, usually pay attention to good protection and minimize exposure to harmful substances.
Rubber manufacturing:In the production process of rubber, more Chemical additives are easily exposed to carcinogens such as aniline, increasing the risk of stomach cancer, bladder cancer, leukemia, and lung cancer.
Steel Casting:There are many stages in the production process that can lead to high cancer rates, such as Furnace smoke easily contains benzopyrene, a carcinogen.
Aluminum Production:Petroleum coke, oxidation Aluminum and other harmful substances such as fluoride, dust, carbon monoxide, asphalt smoke, sulfide, etc., personnel engaged in such work must be well protected when working.
It is worth noting that exposure to these carcinogens does not necessarily lead to cancer, but that these substances are high-risk substances for carcinogenicity. Increased cancer risk. Therefore, we should try our best to avoid or reduce contact with these substances in peacetime to reduce the risk of cancer. #health star Program# #Health2022#
