> Infection with H. pylori is responsible for around 89% of all gastric cancers, and is linked to the development of 5.5% of all cases of cancer worldwide. Although the data varies between different countries, overall about 1% to 3% of people infected with Helicobacter pylori develop gastric cancer in their lifetime compared to 0.13% of individuals who have had no H. pylori infection. H. pylori-induced gastric cancer is the third highest cause of worldwide cancer mortality as of 2018. Because of the usual lack of symptoms, when gastric cancer is finally diagnosed it is often fairly advanced. More than half of gastric cancer patients have lymph node metastasis when they are initially diagnosed. I've got symptoms, but this would scare me even if I didn't.
