In the 21st century, science is more and more developed, but the “radiation pollution” around us is everywhere, such as: cell phones, wireless network (WIFI), electromagnetic radiation, nuclear radiation, medical X-ray examination (CT, DSA, PET-CT), radionuclide therapy, etc. Although the current medical evidence is not sufficient, we can learn from some life experience at home and abroad to do the following: 1. Although the current medical evidence is not sufficient, but for your health and safety and mine, we can learn from some life experience at home and abroad, try to be able to do the following: 1, reduce the threat of cell phones cell phones away from the head before connecting, try to make cell phone calls brief, or use headphones to avoid cell phones close to the head. In addition, frequent use of the radio should also be away from the head. Although there is no conclusive evidence on whether cell phone radiation increases the risk of brain cancer, it is always better to take precautionary measures. If you need to talk for a long time, it is better to use a landline. Only green tea is rich in cancer-preventing polyphenols. Interventional doctors who have been exposed to radiation for a long time have mostly developed the habit of drinking green tea to fight against radiation. Oncology patients who receive radiation therapy should also develop this habit. In addition, British scientists found that people who drink 5 or more cups of coffee a week have a 40% lower risk of brain cancer than those who drink less. In addition, 5 cups of coffee per week can also reduce the incidence of oral cancer and throat cancer to the same extent. Maintaining sufficient water (water or other liquids) can dilute the concentration of carcinogenic substances in urine and make them excreted more quickly through the bladder, thus reducing the risk of tumors. The American Cancer Society recommends drinking plenty of water or beverages every day. 4, choose green vegetables Chlorophyll gives green leafy vegetables vigorous vitality and will also help the body to fight cancer, which contains magnesium has been studied and confirmed to reduce the risk of colon cancer in women. Eat about 130 grams of cooked spinach every day, can provide the body with 20% of the magnesium required. 5, marinate before grilling the meat Thermaltake the meat to save the day to be able to reduce the heterocyclic amines by 80% and prevent esophageal cancer. 6, more whole grain foods Whole grains are better for your health than white bread. A survey done by Harvard Medical School on 38,000 women showed that eating foods with high sugar content can cause a rapid rise in blood sugar, which increases the risk of colon cancer. These problem foods are mainly: white bread, refined rice and sugary pastries. 7. Be aware of pain When you feel bloated abdomen, pelvic pain and urinary urgency, you should seek medical attention as soon as possible. These symptoms may be related to ovarian cancer, especially when the symptoms are intense and frequent. If detected early and treated before the cancer spreads outside the ovary, the 5-year survival rate will reach 90-95%. 8, clothes as little as possible dry cleaning A 2010 study by the U.S. Environmental Protection Agency found that the traditional dry cleaning process uses a solvent called perchloroethylene, which may cause liver cancer, kidney cancer and leukemia. Experts recommend using a mild laundry detergent to hand wash your clothes and dry them naturally. 9, drinking filtered tap water This method can help you avoid some carcinogens or environmental hormones. Many people think that bottled water is cleaner and healthier, but it is not. The US President’s Cancer Research Group recommends that people choose filtered tap water instead of bottled water, because the latter is made of plastic, which may allow harmful contaminants such as BPA to penetrate the water. 10.Exercise away from breast cancer To keep breast cancer away from you, stick to moderate exercise. Two hours of brisk walking per week can reduce the risk of breast cancer by 18 percent. Adhering to regular exercise can help you burn fat, and if there is too much fat, its estrogen production may also lead to breast cancer. After the age of 30, for women, losing excess fat means reducing the risk of breast cancer, endometrial cancer and ovarian cancer. 12. Avoid unnecessary radiological examinations CT scan is an effective tool to confirm the diagnosis, but it is highly radioactive and easy to be abused, about 1/3 of the scans can be completely avoided. Receiving a large amount of radiation may trigger leukemia, so do not perform unnecessary repeat scans or take other alternative modalities such as ultrasound or MRI. 13, blue clothes can protect against the sun Spanish scientists found that blue and red clothes than white and yellow clothes more sun protection. Of course, the head and neck protection is also essential, so don’t forget to wear a hat when you go out. WHO’s new view is that tumors are a “physiological phenomenon” in people over 70 years old, so we don’t have to “talk about cancer”. Only regular medical checkups can detect, treat and cure potential tumors early. Commonly speaking, human body is like a car, regular maintenance can ensure safety. Routine medical checkups for middle-aged people are also responsible for themselves and their families.
