Infection and the role in cancer development

It is almost 40 years since Barry Marshal and Robin Warrens identified and recovered Helicobacter pylori (H. pylori) from gastric biopsy specimens. They later demonstrated the role of H. pylori in peptic ulcers and in 2005, they were awarded the Nobel Prize in medicine for these groundbreaking discoveries. Later, it became clear that H. pylori has a carcinogenic role and the fact that a course of antibiotics influenced cancer occurrence was truly a "game changer".
