Esophageal cancer Causes

Esophageal cancer causes have many factors, the occurrence of esophageal cancer is a gradual process, in the process of carcinogenesis must be one of the main factors and minor factors in the carcinogenesis process also plays a synergistic role in tumor promotion, there are two main factors: First, as a result of diet and lifestyle changes, a large number of eating acidic food, body acidification, unlike cancer cells and normal cells die due to environmental acidification, in fact, cancer cells are normal cells In order to grow in acidic environment, take the initiative to variation, and to continue to stretch from the two types of cancer cells produce a theory, one theory of hypoxia, and the other is the theory of Acidosis. Hypoxic theory pointed out that the healthy cells in the absence oxygen environment, the cells can become cancerous, and the acidification of body fluids leading to dissolved oxygen is decreased, he was a trial to prove the point, and the Nobel prize. Acidosis theory referred to as alkaline cells, accumulation of acidic waste in the vicinity of death is usually, but not hesitate to change the chromosome in order to survive in the acidic environment, and this is the beginning of cancer. Another is the external factors: chemical factors; toadstool pollution, mental element is an important cause of Esophageal cancer.

The two factors, internal factors play a decisive role, and physical survival of acidification for the soaring cancer cells provides a good space.

General esophageal cancer causes include:

1. nitrosamines: nitrosamine compounds is a strong carcinogen, the studies showed a high incidence of esophageal cancer, gastric juice, urine-induced esophageal cancer in the existence of methyl benzyl based nitrosamines, nitroso-pyrrolidine, H nitrosoguanidine. And found that consumption of pickled vegetables and esophageal cancer incidence is proportional to.

2. esophageal mucosal injury: Long-term hi into the hot food, coarse food, drinking strong tea, pepper and more fresh food, such as irritation can cause esophageal mucosal damage, caused by proliferation of anaplastic esophageal mucosa, but also one of the factors that may be carcinogenic. Smoking, drinking liquor also is causes of esophageal cancer. various long-term inflammation of the esophagus may be a precancerous lesion of esophageal cancer.

3. toadstool of cancer-causing factors: moldy food can be used in mice induced by esophageal and gastric precancerous lesions or squamous cell carcinoma. Streptomyces promoter and nitrosamines are such synergistic effect.

4. trace elements: a high incidence of esophageal cancer among serum molybdenum, the molybdenum, molybdenum and urine of esophageal cancer are lower than the molybdenum. Esophageal high incidence of water and soil in the absence of molybdenum, molybdenum by the majority of the tumor suppressor role is confirmed.

5. genetic factors: esophageal cancer has significant phenomenon of familial aggregation, prevalence of high-incidence area for more than three generations of the family often.
