Ways to prevent bladder cancer

Bladder tumors are common tumors with a higher incidence in developed countries or regions. Abroad, the incidence of bladder tumors ranks second only to prostate cancer among male urogenital tumors; in China, it ranks first and has been increasing in recent years. The bladder wall is divided into mucosa, submucosa and muscle layer from the inside to the outside. Outside the muscle layer, it is divided into fat honeycomb tissue and the membrane covering the top of the bladder. The inner wall of the bladder can be divided into the triangular area, the post-triangular area, the neck, the two side walls and the anterior wall. The line between the two ureteral orifices is the bottom line of the triangular area. The triangular area is the main part of the bladder cavity. Most bladder tumors occur in the triangular area, the two side walls and the neck. A recent study by American scientists found that the risk of disease can be reduced by taking in sufficient vitamin E by eating more nuts, olive oil and other foods.

The researchers counted the two most common types of vitamin E, alpha-vitamin E and gamma-vitamin E. The results showed that alpha-vitamin E has a more obvious effect. Foods rich in this type of vitamin E mainly include almonds, spinach, green mustard, pepper, sunflower seeds, and edible vegetable oils such as olive oil, cottonseed oil and rapeseed oil. Taking vitamin E through vitamin supplements has the same effect.

In addition, Harvard University in the United States also announced the results of a 10-year study involving 47,909 men aged 40 to 75, which found that drinking more water (6 to 10 cups a day) can effectively reduce the risk of bladder cancer. This study started in 1988 and explored 22 different liquids, including water, tea, juice, beer, etc. The result is that as long as you drink more liquids, whether it is water, beverages, or even beer and whiskey, you can reduce the risk of bladder cancer, which ranks fourth in the United States, by half. The mechanism may be that the frequent removal of liquid flowing through the bladder can reduce the stimulation of potential carcinogens to the bladder wall. For smokers, the risk of bladder cancer is four times that of non-smokers, and drinking more water can reduce the risk of bladder cancer more significantly. Experts suggest that although drinking enough liquids of various types can reduce the risk of bladder cancer, it is still better to drink water. Drinking more than 10 cups of boiled water a day has no side effects, but it is very beneficial. Why not do it?

Adhere to scientific eating habits and eat more fresh vegetables and fruits. Because fresh vegetables and fruits are rich in vitamins and trace elements, they can decompose carcinogenic substances in the body - nitrosamines. Eat less meat as much as possible, because meat can produce substances with similar structures to aniline and benzidine during metabolism in the body. A survey found that workers in factories using aniline and benzidine chemical raw materials are more likely to suffer from bladder cancer.

People who have the habit of smoking should quit smoking as soon as possible. Studies have shown that cigarettes contain nicotine, tar, tobacco-specific substituents and other toxic carcinogens. People who smoke a lot have higher concentrations of carcinogens in their urine. If the daily smoking index reaches 600 (number of cigarettes smoked per day x number of years of smoking), it reaches the dangerous level of bladder cancer.

The increase in the concentration of bacteria in urine can not only cause cystitis, but also continuously produce adverse stimulation to the bladder mucosa. Over time, the bladder mucosa, under the dual stimulation of bacteria and carcinogens, can gradually cause inflammation and erosion to lead to cancer. To prevent the occurrence of bladder cancer, you should drink plenty of water to dilute the urine and excrete it in time. In this way, the bacteria and carcinogens in the urine will be relatively reduced, which can reduce the stimulation and damage to the bladder mucosa and play a role in preventing bladder cancer.
