If you have had gastric problems like me, you will always wonder if the cause could be ulcers, luckily for me this was not the case, but there are many people who do have a long history of ulcers. A recent study has found that the bacterium that causes stomach ulcers has been linked to causing gastric cancer. However this is nothing to be conserved about as this is not 100% proven as no one really knows how gastric cancer is caused at present, just the bacterium has been found in gastric cancer. I would recommend though getting you checked out at the doctors just to be sure.
