Stomach cancer
As mentioned above, stomach cancer is typically caused by an infection with Helicobacter pylori. Patients with no trace of infection have a very low risk of stomach cancer, and it would be otherwise very rare. That’s why we should look carefully at signs such as continuous abdominal discomfort, acid reflux problems, and any trace of blood in vomit. They are often tell-tale signs that doctors use to diagnose either H. pylori infections or stomach cancer.
