Recently, the World Cancer Research Fund (WCRF) showed through a survey of tens of thousands of cancer patients that one-third of common cancers can be prevented through lifestyle changes, and some “simple changes” in life can greatly reduce the risk of getting cancer. According to the survey, overweight significantly increases the risk of 10 types of cancers, including bowel cancer, breast cancer, liver cancer and prostate cancer. According to the data of World Health Organization, there are about 500,000 new cases of adult cancer related to overweight or obesity every year, accounting for 3.6% of the total number of cancer cases in the world. In fact, maintaining a reasonable weight is the most useful way to prevent cancer. Studies show that storing too much fat causes the body to produce “growth hormone,” which is associated with cancer. Moreover, fat also promotes the body to produce an inflammatory response, which keeps the body in a state similar to fighting infection, which may lead to the development of cancer. 2. Exercise is good for your heart and lungs, and it can also reduce the risk of getting cancer. One in nine bowel and breast cancer patients can prevent cancer by increasing their exercise levels. The reason for this may be that exercise keeps hormone levels within reasonable limits – excessive hormone levels are strongly associated with cancer. In addition, exercise is helpful for the immune and digestive systems. Many people always say they are busy and don’t have time to exercise, but studies show that even only 10 minutes of exercise a day can reduce the risk of cancer. 3. Eat more green vegetables Vegetables and fruits can reduce the chance of oral, throat, esophageal, stomach and lung cancer. Not only that, low-calorie vegetables can help maintain a healthy weight. Research shows that vegetables contain a phytochemical that can improve the ability of cells to fight cancer. 4. Drink less alcohol Excessive alcohol can lead to cancers of the mouth, throat, esophagus, liver, intestines and breast. People should drink as little as possible to avoid cancer. Although scientists have not completely identified how alcohol causes cancer, there are theories that alcohol can damage DNA and increase the risk of disease, and if a person drinks and smokes at the same time, it can increase the damage to the body. There are signs that drinking two glasses of wine a day can reduce the chances of kidney cancer, but consuming more alcohol than this amount is not a good thing. 5, stay away from fizzy drinks and junk food High-calorie chocolate, chips, fries, burgers and other foods may bring obesity problems, and thus increase the risk of cancer. Also high in calories are fizzy drinks, energy drinks, milkshakes and juice shaved ice. What about natural fruit juices? Although it benefits a lot, but high sugar content, it is best not to exceed one cup a day. 6, eat less salt Although more salt can enhance the taste, but it can also lead to high blood pressure and stomach cancer. Since excessive salt can harm the stomach mucosa, scientists believe that salt and stomach cancer may have some connection. The optimal salt intake is less than 6g per day, but this indicator is easily broken – a packet of potato chips may contain more than 0.5g of salt. 7. Refuse sausages and cured meats Sausages and cured meats not only contain excessive amounts of salt, but several pieces of evidence link them to bowel cancer. Compounds such as heme, which maintain the color of red meat foods, may harm the intestinal mucosa. The World Cancer Research Fund recommends not consuming more than 500g of red meat per week, and minimizing processed meat products such as ham, bacon, and garlic salami. Smoking, curing and preserving processes can lead to the production of carcinogens. In fact, red meat is an important source of protein, iron and zinc, as long as you do not eat more than 500g of red meat per week is fine. Recently, a large study published online in CANCER, a peer-reviewed publication of the American Cancer Society, showed that in China, the rate of cancer caused by smoking is close to a quarter of the total number of adults who develop cancer. And these people could have been cancer-free. Smoking causes lung cancer by damaging the cells associated with the lungs, and at first the body is able to repair the damage caused by smoking, but if a person continues to smoke, the body’s repair function cannot keep up with the rate of cell destruction. In addition to potentially causing lung cancer, smoking can also cause cancer in other parts of the body, including: the mouth, throat, esophagus, bladder, kidneys, liver and stomach. The World Cancer Research Fund believes that quitting smoking is the most beneficial thing an individual can do to reduce the risk of cancer.
