Gosh, one third of cancer is “eat” out! And “eat” is the closest to the digestive tract tumors, in China’s malignant tumor incidence, mortality rate ranked in the top six, digestive tract malignant tumors accounted for “half of the rivers and mountains”, much higher than the world’s average level. How to prevent “eating” cancer? Esophageal Cancer, Stomach Cancer Causative factors are related to racial and ethnic factors, long-term smoking and drinking, poor eating habits, nitrosamines, mycotoxins, nutrition and trace elements, Helicobacter pylori and pre-cancerous lesions (HP can lead to gastric cancer, Barrett’s esophagus, atrophic gastritis, gastric ulcers, gastric polyps, residual gastritis). Preventing patients who are at high risk for stomach or esophageal cancer, gastroscopy can help diagnose esophageal cancer and stomach cancer at an early stage. You can also quit smoking and alcohol, correct bad habits, avoid nitrosamines (pickled foods), avoid moldy foods, supplement nutritional trace elements, remove HP and precancerous lesions, and drink less and eat less food that is too hot. Liver cancer Causes related to hepatitis – cirrhosis – liver cancer, aflatoxin, drinking water pollution, alcohol consumption, lack of trace elements. Prevention Chronic active hepatitis and cirrhosis are common causes of liver cancer. Aflatoxin and nitrosamines in food are also carcinogens that cannot be ignored. Research shows that food contaminated by aflatoxin has a strong carcinogenic effect, and consumption of food containing nitrosamines can also induce liver cancer. Avoiding corrupt, spoiled and moldy food, and eating less pickled and fried food can reduce the incidence of liver cancer. People with high risk of liver cancer can be diagnosed early by blood sampling for liver function, serum alpha-fetoprotein (AFP) and liver ultrasound. Pancreatic cancer Causes are related to smoking, poor diet (high fat and high protein, overeating), diabetes, and chronic inflammation. Smoking cessation will reduce the risk of pancreatic cancer in smokers. Avoid excessive intake of sweets, meat and fried food, and increase the proportion of vegetables, fruits and coarse grains in the daily diet. In addition, patients with diabetes and chronic inflammation should pay attention to the suggestion of timely pancreatic imaging and tumor markers, which is expected to lead to early diagnosis of pancreatic cancer. Colorectal cancer Causes are related to irrational dietary structure (too much high-calorie, low-fiber food, hindering peristalsis, promoting the accumulation and absorption of toxins, leading to intestinal cancer), chronic inflammation of the large intestine, colon polyps, environmental factors, and heredity. Prevention must start with diet, eat less or no food rich in saturated fat, including lard, butter, fatty meat, animal offal, fish roe and so on. Eat more foods rich in dietary fiber, such as soybeans and their products, fresh vegetables and fruits, and algae. It is recommended that colonoscopy should be done every 5 years after the age of 50. High-risk groups (ulcerative colitis, familial adenomatous polyposis, hereditary non-polyposis colorectal cancer, familial colorectal cancer, patients with a history of tumors, etc.) are recommended to start receiving colorectal cancer screening at around 40 years of age, and to receive a census on average once every 3 to 5 years. Warm tips: some studies show that: the probability of obese people suffering from tumor is higher than normal people. It is not only easy to eat out of the tumor, fat deposition will also increase the probability of developing tumors.
