Is esophageal cancer an infectious disease?

Is esophageal cancer an infectious disease? In fact, the question of whether the symptoms of esophageal cancer are contagious is probably the most concerned issue for many patients and their families, because this will cause some problems for the patients' families when taking care of the patients. If they do not understand this issue, the patients' families will be afraid when taking care of the patients. So it is necessary for us to understand whether esophageal cancer is contagious.

Esophageal cancer, also known as esophageal cancer, is a malignant tumor that occurs in the esophageal epithelial tissue, accounting for 2% of all malignant tumors. This disease is a common malignant tumor in some countries and regions in the world. China is a country with a high incidence of esophageal cancer in the world, and is also one of the countries with a high mortality rate of esophageal cancer in the world. The average annual mortality rate is 1.3~90.9/100,000, while the world's standardized mortality rate is 2.7~110.6/100,000. Esophageal cancer has a clear geographical clustering phenomenon in China, and areas with high incidence and high mortality rates are quite concentrated. Its incidence is in Hebei, Henan, Jiangsu, Shanxi, Shaanxi, Anhui, and Hubei.

Causes of esophageal cancer:

1. Genetic factors: Esophageal cancer has a significant familial clustering phenomenon. In high-incidence areas, it is not uncommon for families to suffer from the disease for three or more generations in a row. However, esophageal cancer is definitely not hereditary, but is closely related to the family's eating habits.

2. Trace elements and malnutrition: The serum molybdenum, hair molybdenum, urine molybdenum and molybdenum in esophageal cancer tissues of people in high-incidence areas of esophageal cancer are all lower than normal. The soil and water in high-incidence areas of esophageal cancer lack molybdenum, and the anti-cancer effect of molybdenum has been confirmed by most scholars. Malnutrition, insufficient intake of animal protein and lack of vitamins A, B2 and C are common characteristics of the diet of residents in high-incidence areas of esophageal cancer.

3. Damage to the esophageal mucosa: Long-term consumption of hot and coarse food, strong tea, and spicy food such as chili peppers can cause damage to the esophageal mucosa, hyperplasia and metaplasia of the esophageal mucosa, and may also be one of the carcinogenic factors. Smoking and drinking strong alcohol are related to the onset of esophageal cancer. Various long-term esophagitis may be the precancerous lesions of esophageal cancer.

4. Nitrosamines: Nitrosamine compounds are a strong carcinogen. Studies have shown that residents who eat sauerkraut in areas with a high incidence of esophageal cancer have methylbenzyl nitrosamine, nitrosopyrrolidine, and nitrosoguanidine in their gastric juice and urine, which can induce esophageal cancer. It has also been found that the amount of sauerkraut consumed is directly proportional to the incidence of esophageal cancer.

5. Mold carcinogenic factors: Eating moldy food can induce precancerous lesions or squamous cell carcinoma of the esophagus and stomach in mice. This type of mold has a synergistic effect with nitrosamines in promoting cancer.

Is esophageal cancer an infectious disease? In fact, we should not think of the symptoms of esophageal cancer as terrible in our lives. Although this disease is also very dangerous, it is still necessary for us to understand some common sense about it. As for the question of whether esophageal cancer is contagious, I think we can understand the answer to this question through the above causes of esophageal cancer.
