Preventive measures for kidney cancer High-risk groups for kidney cancer: people with family history of hereditary kidney cancer; “fat” men above middle age who smoke, drink heavily and suffer from high blood pressure. To prevent kidney cancer, we should start from changing our own habits as early as possible. Firstly, you should not smoke or quit smoking as soon as possible. Secondly, water is the best preventive medicine. Smokers are prone to kidney cancer because of the long-term chronic stimulation of many toxic substances in tobacco on renal tubules and collecting ducts, resulting in intracellular gene mutation. 2. Diet and environmental factors are also related to the occurrence of kidney cancer. It is necessary to eat less high-fat and high-calorie food, adhere to exercise, control weight and avoid obesity and high blood pressure. Eating more fruits and vegetables such as bananas, carrots and beets can significantly reduce the risk of cancer. The higher the daily intake of fruits and vegetables, the lower the chance of developing the disease. Studies have shown that people who eat 6-8 bananas a day have nearly half the risk of kidney cancer than those who don’t eat bananas at all; regular intake of root plants such as carrots or beets also reduces the risk of the disease by 50-65%. The reason is that bananas and other fruits and vegetables contain a special antioxidant substance, which has a strong function of inhibiting tumor formation. 3, suffering from kidney cysts and other kidney diseases should be actively treated to prevent further development of the disease and restore health as soon as possible. 4.Avoid radiation aggression and use hormones carefully. Develop good hygiene habits, do not eat moldy and rotten pickled food. It is advisable to use a light diet, and eat fish, eggs and a small amount of lean animal meat appropriately. 5, antipyretic and analgesic agents, such as finasteride and other drugs should be used under the guidance of a doctor. 6.Participate in physical exercise regularly to enhance physical fitness. Balance the diet, increase nutrition, keep a happy mood and increase the immunity of the body. Patients recovering from surgery should be reviewed regularly, once every 1-3 months, and in good condition once every six months to a year, and adhere to comprehensive treatment.
