Helicobacter pylori that has proved as a cause of stomach ulcers also has link with stomach cancer, a new study suggests.
The researchers investigated the cases of 550 people who had surgery for their stomach cancer. They found that the risk of developing cancer second time decreased twice by using antibiotics that killed Helicobacter pylori.
To find whether killing of the bacterium really stops the development of the cancer, more than 56,000 British people will be under a trial soon.
H.pylori invades the stomach and it is considered the cause of more than 90% of duodenal ulcers and 80% of gastric ulcers.
