Yes, Gastric Cancer is caused by H. pylori infection, by a stepwise progression from chronic superficial gastritis to intestinal type cancer. There is increased prevalence of H. pylori association with gastric cancer. It is estimated that H. pylori infection increases the risk of gastric cancer 6 times. There have been studies on gastric MALT [Mucosa Associated Lymphoid Tissue] lymphoma which is caused by H. pylori, however research has shown that 5 of 6 early lymphomas regressed after eradication of H. pylori.
