Esophageal cancer has a great relationship with the eating habits of people in daily life. Some patients like to eat hot or coarsely processed food, drink strong tea, eat more chili pepper and other stimulating foods, which can cause esophageal mucous membrane damage and interstitial esophageal mucous membrane hyperplasia, which may also be one of the cancer-causing factors. Smoking and drinking strong alcohol are inevitably related to the development of esophageal cancer, and various kinds of long-term untreated esophagitis may be precancerous lesions of esophageal cancer. Why do people suffer from esophageal cancer? Esophageal cancer may not be well understood by some people, but in reality, this disease is very close to our life and is a great threat to the physical and mental health of patients. If we don’t pay attention to it sometimes, it may directly threaten the patient’s life. 1. Mycogenic factors Why do people suffer from esophageal cancer? This is one of the factors that can lead to esophageal cancer. Moldy food can induce precancerous lesions or squamous epithelial carcinoma in the esophagus and stomach of mice, and such molds have synergistic effects with nitrosamines to promote cancer. 2.Microelements and malnutrition Secondly, in the relevant data, esophageal cancer is found to be directly related to microelements and malnutrition through research. In some areas with high incidence of esophageal cancer, serum molybdenum, hair molybdenum, urine molybdenum and molybdenum in esophageal cancer tissues are all lower than normal. The lack of molybdenum in the soil and water in areas with high incidence of esophageal cancer, and the cancer suppressing effect of molybdenum is confirmed by most scholars. Esophageal cancer also has a great relationship with people’s dietary habits in daily life. Some patients like to eat hot or coarsely processed food, drink strong tea and eat irritating food such as chili pepper, which can cause esophageal mucous membrane damage and interstitial esophageal mucous membrane hyperplasia, which may also be one of the cancer-causing factors. Smoking and drinking strong alcohol are inevitably related to the development of esophageal cancer, and various kinds of long-term untreated esophagitis may be precancerous lesions of esophageal cancer.
