Drinking plenty of water can reduce the occurrence rate of bladder cancer
The occurrence rate of bladder cancer increases proportionately with the time that the urine stays in the bladder. The carcinogens may infringe the bladder fibers, destroy the normal cells structure and then cause malignant changes. Researchers once compared urine which was discharged per hour with that was discharged every2-3 hours and found that the latter contains significantly more carcinogens than the former.
Researchers from Harvard University once have a follow-up study on nearly 50,000 males at the age of 40 to 75 years old. They found that when compared to males who drink 6 cups of water every day, those who drink 1 cup of water have one times higher risks for bladder cancer.
It is worth mentioning that, in some countries, running water is chlorinated disinfecting and sterilized treating, and the treated water can isolate 13 kinds of harmful substances, among which, hydrocarbons and chloroform have carcinogenic or teratogenic effects. When the water is boiled to the temperature of 100 ℃, this two kinds of harmful substances will evaporate with water vapor and greatly reduced. If the water is continue to be boiled for 3 minutes, it is safe to drink.
Water can reduce the toxicity of tobacco
Studies have shown that the risk of smokers’ occurrence to kidney cancer is two times higher than no-smokers and male smokers’ chance to develop into kidney cancer is 1 times higher than female smokers. The longer smoking time one is involved in, the larger the amount of cigarette he is having, the higher risk he will develop into kidney cancer.
To prevent kidney cancer, one should firstly be a non-smoker or quit smoking. Secondly, water is the best preventive “drug”. Why smokers are inclined to suffering from kidney cancer is because tobacco contains many toxic substances which will have long-term chronic stimulation to the renal tubule and collecting duct. This leads to intracellular gene mutation, while drinking more water can reduce the concentration of tobacco toxins.
Eat plenty of bananas and carrots
Dietary and environmental factors also related to the occurrence of kidney cancer. Eating less high-fat and high calorie food, taking continuous exercise and controlling weight can help to avoid obesity and hypertension. Also, eating bananas, carrots and other fruits and vegetables can reduce the risk of cancer. The greater the amount of daily intake of fruits and vegetables is, the smaller the risk that one will suffer from cancers. According to some survey, people who eat bananas everyday has nearly 1 times lower risk of occurring to kidney cancer than those who don’t take any banana. Regular intake of carrots or beet root vegetables may reduce a 50%-65% risk of cancer occurrence. The reason is that these fruits and vegetables contain a particular type of antioxidant substances, which have strong cancer formation inhibited function.
