Dietary molybdenum deficiency from low soil concentration of molybdenum has been associated with increased rates of esophageal cancer in a geographical band from northern china to iran [ 48 ] [ 49 ] compared to the united states, which has a greater supply of molybdenum in the soil, people living in these areas have about 16 times greater risk. (natural news) a new study finds that zinc supplements can help prevent cancer in the esophagus, as reported by science daily researchers at the university of texas at arlington (uta) evaluated the reaction of human esophageal cancer cells and healthy human cells to zincthey discovered that zinc supplements slowed down the growth of esophageal cancer cells. Genetic factors in precancerous lesions and cancer of the esophagus the etiologic factors implicated in esophageal cancer development differ either between low-risk and high-risk areas, or among countries with a zinc and molybdenum dificiency of the soil. Betel and areca nuts have also been associated with the development of esophageal cancer in china, foods high in nitrates may double the risk the risk is also higher for those who have vitamin and mineral deficiencies (especially folate, vitamin c, and molybdenum) in developing countries.
Esophageal cancer is a malignancy that develops in tissues of the hollow, muscular canal (esophagus) along which food and liquid travel from the throat to the stomach esophageal cancer usually originates in the inner layers of the lining of the esophagus and grows outward in time, the tumor can. Furthermore, in other areas that have a high risk of esophageal cancer, such as parts of northern iran and south africa, molybdenum levels in hair and nail samples have been found to be low (14, 15. In regions in which the soil is deficient in molybdenum and zinc, plants are impaired in their ability to metabolize nitrites to ammonia mouth and esophagus), perforation of the esophagus with the development of fistulas (connections with other organs such as the trachea), infection, bleeding, xerostomia (dryness in the mouth) and fatigue.
Disease prevention esophageal cancer linxian is a small region in northern china where the incidence of cancer of the esophagus and stomach is very high (10 times higher than the average in china and 100 times higher than the average in the us) the soil in this region is low in molybdenum and other mineral elements therefore, dietary molybdenum intake is also low. (naturalhealth365) zinc is the second most prevalent mineral in the human body, second only to iron it is essential in the production and function of over 300 enzymes and hormonesbut, its link to cancer risk is very interesting. Molybdenum is one of the lesser known trace elements in human nutrition nevertheless, it is essential for human health molybdenum is believed to have a protective effect against the development of cancer of the esophagus zinc and other micronutrients keats publishing, 1978.

Methods: barrett’s esophagus patients were administered oral zinc gluconate (26 mg zinc twice daily) for 14 days prior to biopsy procurement barrett’s biopsies were analyzed for total zinc content by atomic absorption spectroscopy and by western immunoblot for cellular proteins known to be regulated by zinc. Treatment of esophageal cancer poses difficult problems for health care providers the disease has a poor prognosis early detection and further identification of effective treatment modalities may be the only hope for improving survival rates of patients with esophageal cancer.
