What are the mainstream screening techniques for digestive tract cancer? What are the preventive suggestions?

Nitrite does not directly induce cancer. Protein (including nitrogen) should be converted into nitrosamines in acidic environment in the stomach. This substance is a carcinogen, which directly damages the DNA of cells and has the greatest influence on the formation of gastric cancer, followed by esophageal cancer and rectal cancer. Which foods contain more nitrite? It should be noted that medical research on smoked food, processed meat and overnight vegetables, as well as rich vitamin C in fresh fruits and vegetables can reduce the conversion of nitrite to nitrite. Most pickled foods contain a lot of salt, which directly damages the gastric mucosa and has the risk of inducing gastric cancer.

Polycyclic aromatic hydrocarbons (PAHs), such as acetylene and benzopyrene, are produced in the process of frying and grilling food at high temperature, and are listed as carcinogens by the World Health Organization. Delicious temptation can be eaten occasionally, but it is always a bad way to eat. Fungal changes in food are also the cause of digestive tract tumors, especially esophageal cancer. Now some people may say that someone is eating bad food. Thrift is a virtue. People often remove fungi visible to the naked eye from food. Not invisible to the naked eye. In that case, waste a little. Pay attention when placing rice, cotton, oil, soybeans, peanuts, etc. When food becomes thick, hard and hot, the physical damage of esophageal mucosa and gastric mucosa will work for a long time, and small inflammation and ulcers will slowly proliferate. The World Health Organization classifies more than 65% foods as Class A carcinogens. In addition, overeating and irregular diet are also high risk factors for gastric cancer.

Animal food with high protein, high fat and low cellulose is the biggest risk factor for colorectal cancer. These foods need more bile to digest and metabolize, forming more bile acids and methyl cholanthrene. Low-cellulose food is a carcinogen, which prolongs the residence time of methyl cholagogue, getting worse and worse, and the risk of cancer is greater. Cancer of digestive tract mainly refers to cancer of digestive system, such as gastric cancer, colon cancer and esophageal cancer. With the improvement of living standards and the acceleration of the pace of life, more and more people are divorced from the track of normal life, work and diet.

Gastric cancer is a gastrointestinal risk factor for gastric cancer, including food, habits and high-salt diet, especially pickled vegetables, smoked and rotten food. In addition, people who often drink alcohol, excessive alcohol intake will lead to gastric mucosal damage, ulcers, gastritis and so on. If it is not controlled for a long time, it is easy to get gastric cancer. In addition, because of frequent mood swings, overeating and losing weight are risk factors for gastric cancer. Esophageal cancer and esophageal cancer are also high-risk cancers at present. I know some are habitual problems, but some are impossible. Some people like to heat some food, thinking that heating some delicious food will burn the mucosa of the esophagus and cause esophageal inflammation. If it is not corrected for a long time, it will add new wounds. Now people induce vomiting or broadcast in order to lose weight or achieve the ultimate goal. Then gastric acid reflux esophagus can also cause mucosal damage.
