1, maintain a reasonable dietary structure Normally, we should pay attention to consume more vegetables and fruits to ensure that the body has enough vitamins and trace elements to facilitate the decomposition of carcinogenic substances in the body, such as nitrosamines. The risk of bladder cancer may be increased by the large intake of fat, cholesterol, fried food and red meat, which can produce substances similar to aniline and benzidine structure during the metabolism of meat in the body. Experimentally, these substances are prone to induce bladder cancer. Some studies have shown that the intake of more soy foods and soda may increase the risk of bladder cancer.
2, Quit smoking and limit alcohol Smoking is the most certain risk factor for bladder cancer, 30%~50% of bladder cancer is caused by smoking, and smoking can increase the risk rate of bladder cancer by 2~4 times. Nicotine, tar and other specific nitrosamines in cigarettes are toxic carcinogens that can easily induce bladder cancer. The metabolism of tryptophan, a carcinogen in the urine, increases in continuous smokers, while tryptophan levels return to normal once smoking stops. Heavy smokers have higher concentrations of carcinogens in their urine. Of course, passive smokers can also suffer. Non-smokers should not learn how to smoke. So from the perspective of bladder cancer prevention alone, it is also important to resolve to quit smoking. In addition, although the relationship between alcohol and bladder cancer is not clear, some studies show that the incidence of bladder cancer in drinkers is 2.53 times higher than that in non-drinkers.
3.Strengthen occupational protection Another important risk factor for bladder cancer is long-term exposure to industrial chemical products, about 20% of bladder is caused by occupational factors. Doctors found that people with long-term exposure to aromatic amines, such as rubber, plastics and chemicals, are prone to bladder cancer, and the risk of its development is proportional to the length of exposure to aromatic amines, the size of the dose and the degree of closeness. After occupational carcinogens enter the body, they are metabolized and decomposed, and certain carcinogenic components are stored in the bladder with urine as waste. Therefore, occupational protection should be strengthened and labor protection facilities should be improved to prevent carcinogens from entering human body through respiratory or digestive tract as much as possible.
4. Eliminate local inflammation and other cancer-promoting factors Early treatment of chronic cystitis, bladder stones, tuberculosis and foreign bodies, or elimination of local irritants can effectively prevent bladder malignancy. Physical, chemical or biological undesirable factors in the bladder that irritate the bladder mucosa for a long time will lead to cellular heterogeneous proliferation, monolayer flat epithelial tissue transformation, cystic tissue transformation or glandular tissue transformation, and eventually malignant transformation to bladder cancer. Parasitic diseases, such as schistosomiasis, can also cause bladder cancer if left untreated for a long time.
5.Drink more water and urinate more often Normally, you should develop the habit of drinking more water, drinking more tea and urinating more often. Generally, you should urinate once every 1~2 hours. More urine can reduce the concentration of carcinogens in the urine in the bladder and reduce the damage to the bladder mucosa. In addition, the less water you drink, the longer the interval between urination is bound to be, which creates favorable conditions for certain bacteria, such as E. coli, to multiply in the bladder. The increased concentration of bacteria in urine not only induces cystitis, but also continues to stimulate the bladder mucosa, further aggravating the damage to the bladder wall and leading to bladder cancer. Data has shown that most bladder cancer patients are those who usually drink less water and tea. Therefore, not only should they drink more water and tea, but also should urinate regularly and never hold urine.
In addition, the application of chemotherapy drug cyclophosphamide, abuse of painkillers containing finasteride, recent and long-term history of pelvic radiotherapy, long-term consumption of water with high arsenic content and chlorine disinfected water, coffee, artificial sweeteners and hair dye may also be causative factors of bladder cancer and should also be noted.
