Pylori bacteria hikes stomach cancer risk 5-fold

This is something new from the medical world of Japan.

According to wiki,

Helicobacter pylori is a bacterium that most often infects the mucus lining of the stomach and duodenum. Many peptic ulcers, and some types of gastritis are caused by H. pylori infection. It is estimated by some researchers that approximately 50% of the world's population is infected, although most humans who are infected will never develop symptoms. This bacterium is the only known microorganism that can thrive in the highly acidic environment of the stomach. Its helix shape (hence the name helicobacter) is thought to have been designed to penetrate the mucus lining to colonize.

TOKYO — The risk of people getting stomach cancer could increase 5.1-fold when they are infected with helicobacter pylori bacteria, greater than the "nearly threefold" increase that has been suggested by past research, a survey by the Japanese health ministry's research team showed Monday.

The team, led by Shoichiro Tsugane who heads the National Cancer Center's Epidemiology and Prevention Division, warned that the risk of developing stomach cancer is greater than was believed in the past as more than 70% of Japanese in their 40s are thought to be infected with the bacteria.
