Predominates in males, with a male / female ratio equal to 4 / 1, although the very high incidence areas of this relationship is reduced.
Several are considered precancerous esophageal lesions, including esophagitis, caustic stand, Barrett’s esophagus, achalasia and dysphagia sideropenic (Plummer-Vinson syndrome).
Other conditions are associated significantly with the development of esophageal neoplasia, such as palmoplantar keratosis and celiac disease, but their relationship is still not fully confirmed.
There are several risk factors that significantly increase the likelihood of developing this cancer, such as chronic use of snuff and alcohol. These have been mentioned as the main risk factors in Europe and America.
Diets low in vegetables and fruits, beverages and food intake excessively hot, and the presence of nitrosamines in foods are also certain risk factors, especially in areas of highest incidence.
