So, can cancer be prevented?
Researchers from the American Cancer Center published a research paper in the Journal of the American Medical Association: Internal Medicine, saying that through data analysis of 1.44 million people in the United States and Europe, they found that the incidence of at least 13 cancers in people who exercise for a long time is significantly lower! So far, this is the largest and most comprehensive study of articles on exercise and cancer incidence.
The paper in the Journal of the American Medical Association integrates many previous research data, surveyed the daily exercise volume of 1.44 million people in Europe and the United States, and then compared the two groups of 10% who exercise the most and the 10% who exercise the least. The entire exercise research data statistics span from 1987 to 2004, spanning 18 years, and the cancer incidence data tracking time is longer.
How can sports prevent cancer?
What is the principle of exercise to prevent cancer? In recent years, sports medicine research, tumor experimental research, and tumor cause investigation have gradually revealed the mystery and clarified many new mechanisms.
1. Improve the body's immune function and help prevent cancer
Studies have found that cancer cells can only grow and reproduce when they escape human immune surveillance; if a person’s immune mechanism is intact, no cancer will occur; if cancer patients can maintain and improve their own immune function, they can effectively Suppress and defeat cancer. Studies have confirmed that regular exercise can effectively improve autoimmune function. For example, exercise can significantly increase the body's immune cells such as T lymphocytes, B lymphocytes, and phagocytes, thereby enhancing the body's ability to prevent cancer. Exercise can also increase the level of interferon in the blood, and interferon is also the body's immune enhancer, which has anti-cancer and anti-cancer effects.
2. Breathing in more oxygen is beneficial to inhibit cancer
Exercise can make people inhale several to several tens of times more oxygen than usual. The human body’s oxygen intake increases and the breathing rate increases. Through the frequent exchange of gas in the body, more carcinogenic toxins can be discharged and the incidence of cancer can be reduced. At the same time, cancer cells are anaerobic cells that require insufficient oxygen for survival and growth. The environment; the internal environment with sufficient oxygen is not suitable for the growth of cancer cells, so it is more conducive to inhibiting cancers latent in the body. According to the research of German sports medicine professor Van Aken: “A person gets more than 8 times more oxygen per day than usual, which can prevent cancer, and even if they have cancer, they can prolong their life.” Mexican oncologists tested 100 cancer patients. Three years of experimental observations found that with 2 hours of oxygen therapy a day, the survival rate of cancer patients can rise from 32% to 88%.
3. Prevent cancer cells from "settlement" and "metastasis"
Human blood circulation speeds up during exercise. At this time, cancer cells are like small sand in the turbulent flow. They are not easy to "stand on their heels". Therefore, it is not suitable for cancer cells to "settle" to form spreading and metastasis; they are often affected by immune function during blood flow. The strong immune cells are eliminated.
4. Exercise can cause more sweating and discharge more carcinogens
Every time you exercise, you will sweat much more than usual. Excessive sweating can excrete carcinogenic poisons such as nitrite, acetone, chloroform, sulfur, phenol, strontium, lead, mercury, and beryllium that are accumulated in the body to prevent cancer.
5. Improve the activity of antioxidant enzymes and effectively remove free radicals
The human body produces a large number of free radicals in its metabolism. The accumulation of excessive free radicals in the body can damage cell membranes, proteins, nucleic acids and induce more than 200 diseases. It can also cause cell mutations and develop cancer. However, the human body also has a system for removing these free radicals. The function of scavenging free radicals is called "anti-oxidation". For example, superoxide dismutase and glutathione peroxidase in the human body are antioxidant enzymes that can effectively scavenge free radicals. The higher the activity of antioxidant enzymes in the human body, the stronger the function of scavenging free radicals, which can prevent many diseases and even cancer.
6. Exercise regularly to control blood sugar levels and "starve" cancer cells
Nobel Prize winner Dr. Otto Warburg discovered for the first time that cancer cells and healthy cells are fundamentally different in terms of energy metabolism. Cancer cells ferment glucose in an anaerobic environment. Its absorption of glucose is 3 to 5 times that of healthy cells. It directly uses blood sugar as nutrition and almost only eats sugar. Regular exercise can promote metabolism, control blood sugar, maintain a good blood sugar level, and can selectively "starve" cancer cells present in the body, which is beneficial to cancer prevention and anti-cancer.
7. Prevent fat and lose weight, reduce the risk of multiple cancers
Studies have shown that obesity is closely related to the occurrence of certain cancers. Obesity in men can increase the incidence of colorectal cancer and prostate cancer; obesity in women can significantly increase the incidence of uterine cancer, cervical cancer, ovarian cancer, breast cancer, and gallbladder cancer. And regular exercise can prevent obesity and have a weight loss effect. People with normal weight should consume all the calories they take in through exercise every day to achieve a "balance of income and expenditure" to prevent gaining weight; while for obese people, the calories consumed every day should exceed the calorie intake, which is beneficial. lose weight.
8. Exercise promotes bowel movement, avoids constipation, and helps prevent cancer
The stool of the intestinal cavity contains a variety of carcinogens and carcinogens. For people with frequent constipation, the carcinogens and carcinogens in the stool can stimulate the intestinal mucosa in a large area, high concentration, and for a long time and easily induce a variety of cancers. Exercise can promote bowel movements, accelerate bowel movements, reduce the concentration of toxins in the stool, reduce the area of contact with the intestinal wall, reduce the time to stimulate the intestinal mucosa, and greatly reduce the risk of cancer.
9. Female friends who insist on exercising are particularly effective in preventing women’s cancer
Medical experts conducted a 21-year investigation and research on 8,000 Japanese in Hawaii and confirmed the effect of exercise on cancer prevention. In particular, women benefit more from exercise. Research results show that exercise can regulate female endocrine hormones (such as estrogen, prolactin), thereby reducing hormone-dependent breast, ovarian, uterine, and other gynecological cancers by 50%. American cancer expert Jerome Bullock pointed out that the most reliable way to prevent gynecological cancer is to insist on aerobic exercise for 3 hours a week. Exercise can prevent a variety of cancers related to endocrine hormones.
10. Exercise can invigorate people and improve their ability to prevent cancer
A well-known American oncologist pointed out: “Cancer is the failure of immune function, and the failure of immune function occurs after the mental balance is disrupted.” Clinical diagnosis and treatment have observed that about 3/5 of cancer patients are due to trauma and emotional depression. And suffering from cancer or causing cancer to develop. Persistent exercise can regulate the secretion of human hormones, promote blood circulation in the brain, invigorate people, and cultivate sentiment. Exercise can make the human body secrete the brain chemical substance called "the river of happiness of consciousness"-cephalin. The chemical substance can regulate the function of the nervous system, improve mental stress, exercise will, make people feel happy, help eliminate worries and worries, and improve the ability to prevent cancer.
Which cancer risks can be reduced?
Regarding the cancer risks that exercise can reduce, this article studied 26 types of cancer and found that exercise significantly reduced the incidence of cancer. The percentage of reduction in the incidence of 13 types of cancer is shown in the figure.
Of the top 10 cancers in China, 8 of them can reduce the risk through exercise. Esophageal adenocarcinoma reduced by 42%! Liver cancer 27%! Lung cancer 26%!
The cancers with the highest mortality rates for men and women in my country are lung and bronchial cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, accounting for three-quarters of all cancer deaths.
In order to make the conclusion rigorous, the researchers analyzed the surveyed subjects' race, geographic location, education level, age, body weight, smoking, drinking status, hormone therapy, and other conditions and found that the above conclusions are not affected.
How long is the best exercise?
Understand the principle that exercise can prevent cancer, so what exercises can prevent cancer, and how long is the appropriate exercise time?
Experts from the American Sports Association believe that aerobic exercises such as jogging, cycling, and swimming are most suitable. The ideal exercise rhythm is three times a week for at least 30 minutes each time, or four times a week for at least 20 minutes each time. As long as you go to the gym and walk or jog easily, you can easily achieve this rhythm. It is important to persevere.
In fact, in summary, exercise does not really prevent cancer from occurring. It can only help you exercise your body, regulate immunity, and reduce the chance of cancer, but excessive exercise will also reduce your body’s immunity! In addition, there are air, water sources, mentality, etc. that affect your health.
Exercise is not omnipotent, but no exercise is absolutely impossible!
