(1) Smoking: Smoking is the most important unhealthy lifestyle leading to cancer, which can induce a variety of cancers. It is found that the incidence of lung cancer, laryngeal cancer and esophageal cancer in long-term smokers is 10 to 20 times, 6 to 10 times and 4 to 10 times higher than that in non-smokers.
(2) Drinking: There is ample evidence that alcohol will increase the risk of esophageal cancer, gastric cancer, liver cancer, colorectal cancer and breast cancer, and studies have shown that alcohol may also lead to lung cancer, pancreatic cancer and skin cancer.
(3) Obesity: Studies have shown that obesity is closely related to the occurrence of thirteen kinds of cancers such as postmenopausal breast cancer, colorectal cancer, endometrial cancer and esophageal adenocarcinoma. The most commonly used measure of obesity is body mass index, that is, weight divided by the square of height. China's standard body mass index ranges from 18.5 to 24, which is overweight. Once it exceeds 28, it is obese. From the perspective of cancer prevention, the weight should be controlled between 18.5 and 24.
(4) Staying up late: Some studies have found that staying up late and living irregularly will increase the risk of cancer. In addition, staying up late for a long time will make cancer more difficult to control.
(5) Excessive intake of red meat: Red meat refers to the meat of all mammals, such as pigs, sheep, cattle and meat. It is recommended to consume 350 to 500 grams of cooked meat every week. Studies have shown that eating too much red meat will increase the risk of colorectal cancer. On the one hand, when people cook red meat, they usually fry it, which will produce carcinogenic heterocyclic amines and polycyclic aromatic hydrocarbons. In addition, heme iron rich in red meat can promote the canceration of colorectal cancer by stimulating the formation of nitroso compounds.
(6) Too little intake of fruits and vegetables: increasing the daily intake of fruits and vegetables can reduce the risk of cancers such as esophageal cancer, oral cancer, nasopharyngeal cancer, lung cancer, gastric cancer and colorectal cancer. Dietary fiber rich in food can inhibit the proliferation of intestinal cancer cells by improving the production of beneficial short-chain fatty acids by intestinal flora; At the same time, most fruits and vegetables are rich in carotene, vitamins, phenolic acids, selenium and flavonoids, which have the potential to prevent cell mutation.
To prevent cancer, it is necessary to control weight, exercise for more than 30 minutes every day, eat more fresh fruits and vegetables, limit fat intake, drink green tea every day, quit smoking, limit alcohol and reduce salt, stay away from various carcinogenic factors, and maintain physical and mental relaxation, all of which can help people stay away from cancer.
At present, China basically has universal health insurance, and basically a part of medical care can be reimbursed. Everyone's income level has also improved, and at the same time, their cultural literacy and health awareness have also improved. Therefore, we pay more attention to our own health, not only diseases, but also plastic surgery is very popular in recent years, which shows that we not only care about our own health, but also care about our own beauty.
2. Progress in medical technology
With the progress of medical technology, many diseases have been found and treated early, and the accuracy of diagnosis is also improving. Diseases that were previously considered incurable can now be treated. Saved many lives and eliminated many infectious diseases, such as plague and smallpox.
3. Environmental pollution
There is indeed pollution in our living environment, including air, water, food and so on, waste oil, poisoned milk powder and so on. The rising incidence of lung cancer is closely related to air pollution.
4. Changes in living habits
Sedentary, inactivity, smoking, drinking, staying up late, obesity, high-calorie diet, etc., will all lead to the occurrence of diseases, as well as stress in life and mental stress, so that the incidence of cardiovascular and cerebrovascular diseases, diabetes and cancer continues to rise. These diseases are chronic and consumptive diseases, which greatly threaten everyone's personal safety.
