Answer

Stomach cancer is a major disease linked to Helicobacter pylori, a type of bacteria that infects the stomach. H. pylori causes chronic inflammation in the stomach lining, which can lead to the development of stomach ulcers and, in some cases, stomach cancer. The bacteria are typically acquired during childhood and can persist in the stomach for decades, increasing the risk of developing stomach cancer over time.
