Causes of<unk>  cancer depend on the type of cancer. Adenocarcinomas are caused by genetic modulations due to chronic inflammation mainly by H. pylori infection. Diffuse gastric carcinomas do not have a precancerous lesion. Somatic mutations in the CDH1 gene by hypermethylation, mutation, and loss of heterozygosity are identified in 40 to 83 percent of sporadic diffuse-type gastric cancers. The E-cadherin gene (CDH1) encodes a transmembrane cellular adhesion protein.
