The United States released the latest report, adding 8 carcinogens! Please keep this 'carcinogen list'

Some time ago, a 12-year-old boy in Zhejiang was diagnosed with advanced pancreatic cancer, which caused heated discussions among parents. Everyone was worried that cancer was getting closer and closer to us.

Cao Yongqing, director of the Department of Hematology and Oncology, said that there are more and more external carcinogenic factors, and more and more cancer-causing opportunities are exposed in life, so the age of cancer patients will be relatively younger. He reminded that daily exposure to carcinogens should be avoided as much as possible.

Not long ago, the National Institutes of Health updated the latest list of carcinogens , which is worthy of our reference.

1. The latest report on carcinogens in the United States, with 8 new species added

The official website of the National Institutes of Health (NIH) released the 15th edition of the " Carcinogen Report ", adding 8 carcinogens , bringing the total number of carcinogens in the list to 256.

In the latest report, chronic H. pylori infection is listed as a "definite human carcinogen" , while antimony trioxide as a flame retardant and six haloacetic acids , which are disinfection by-products of tap water, are listed as "reasonably suspected" human carcinogens".

· Helicobacter pylori

Helicobacter pylori is a bacterium that colonizes the stomach and can cause gastritis and peptic ulcers. Research in recent years has shown that chronic infection with Helicobacter pylori may trigger gastric cancer and a rare form of gastric lymphoma.

· Antimony trioxide

Antimony trioxide is primarily used as a flame retardant in plastics, textiles, and other consumer products , and can pose a hazard to those who produce and use it. In addition, flame retardant treated consumer products (eg carpets, furniture) may also release this substance.

6 kinds of haloacetic acids

Disinfection of tap water requires the use of large quantities of chlorine-based disinfectants, which may generate haloacetic acids, which may have teratogenic and carcinogenic effects. There are 6 haloacetic acids included in the report, namely bromochloroacetic acid, bromodichloroacetic acid, chlorodibromoacetic acid, dibromoacetic acid, dichloroacetic acid and tribromoacetic acid. Generally speaking, tap water that meets the standard can be used with confidence.

2. The most complete list of class 1 carcinogens

At present, the most comprehensive list of carcinogens in the world is the list of carcinogens published by the World Health Organization . Among them, Category 1 carcinogens are definitely carcinogenic to humans , and they are the most vigilant. There are 120 kinds of them, including many substances that can be exposed to daily.

Staying away from these 120 group 1 carcinogens can help reduce the risk of cancer. The specific list is as follows:

3. 14 "iron laws of cancer prevention", worth memorizing

In order to curb the development of cancer, the American Cancer Society released the "Cancer Primary Prevention Plan", from which Xiaojiu sorted out 14 "iron laws of cancer prevention", which are worth keeping in mind.

1. Quit smoking

Tobacco contains 250 harmful chemicals, nearly 70 of which can cause cancer. In addition to lung cancer, cigarettes have also been linked to cancers of the stomach, bladder, kidney, mouth, and throat. The sooner you quit smoking, the greater the reduction in cancer risk.

2. Eat more fruits and vegetables

Fruits and vegetables are rich in nutrients, high in fiber and low in fat. Eat more broccoli, kale, cabbage or other cruciferous vegetables every day to help reduce DNA damage in cells. Also eat more colorful berries, which are high in antioxidants.

3. Weight control

Obesity, especially abdominal obesity, may increase the risk of cancers such as breast, colon, uterus, pancreas, esophagus and gallbladder.

4. Drink less alcohol

Numerous studies have linked alcohol to oral, breast, liver, esophageal and other cancers, and the more alcohol you drink, the higher your risk. If you usually drink alcohol, remember to be in moderation, preferably not a drop.

5. Eat less processed meat

Processed meats, such as hot dogs, bacon, and sausages, contain nitrites and nitrates that may be linked to cancer. Some studies have also found that excessive intake of red meat may lead to long-term risk of colorectal cancer. It is recommended to eat less processed meat and replace some red meat with poultry or fish.

6. Multi-activity

Avoid prolonged sitting and exercise more. Exercise can fight obesity and reduce cancer-related hormone levels. It is recommended to exercise at least 3 times a week for more than 30 minutes each time.

7. Apply sunscreen

UV rays can damage the skin and increase the risk of skin cancer. It is recommended to apply sunscreen 15 minutes before going out , and if you are going outdoors in the sun, wear a wide-brimmed hat and sunglasses.

8. Safer sex

Unprotected sex increases the risk of sexually transmitted diseases, which in turn increases the risk of some cancers. For example, about 70% of cervical cancers originate from human papillomavirus (HPV) types 16 and 18, and some hepatitis viruses can also cause liver cancer.

9. Get vaccinated

Some vaccines protect against cancer, such as the HPV vaccine against cervical, vulvar, vaginal and anal cancers, and the hepatitis B vaccine against the virus that causes liver cancer.

10. Stay away from carcinogens

Some people may be exposed to carcinogens at work or in life. Although it cannot be completely avoided, we can know in advance whether the item contains carcinogens. If so, try to use safer items.

11. Know your family history of illness

Cancer has obvious genetic predisposition. It is recommended to know the family's disease history, whether there is a family history of certain cancers, and to perform genetic testing if necessary, to assess genetic risk, and to take preventive measures.

12. Cancer Screening

Cancer screening can detect cancer or precancerous lesions early, such as colonoscopy, Pap test, breast ultrasound combined with X-ray, low-dose spiral CT, etc. Before getting a cancer screening, you should talk to your doctor about how often you need to be screened .

13. Take medicines as prescribed

Some medicines may reduce the risk of certain cancers, but be sure to consult a professional doctor first, and take them as prescribed. Do not make decisions without authorization. Also, be wary of supplements that claim to keep you safe from cancer, as many are unscientific and even have serious side effects.

14. Be cautious about hormone therapy

While hormone therapy can relieve menopause symptoms and help protect bones, it may also increase breast cancer risk. Before receiving hormone therapy, be sure to consult a professional doctor in a regular hospital.

Cancer is the result of the interaction of many factors. It cannot be simply attributed to a certain cause. What we can do is to try to stay away from carcinogens, eat a variety of diets, pay attention to balanced nutrition, exercise properly, control weight, and maintain a good attitude.
