H Pylori and stomah upset

I've been diagnosed with H-Pylori levels of 565. When asked 565 of what? I was told the normal range is between 50-150 and I'm way above the limit. I was also told that this bacteria is the main cause of stomach cancer. I actually had irritable bowel syndrome and after two weeks of medication my irritable bowel syndrome still remains. Now to my questions. a) Does H Pylori cause stomach cancer. b) Does H-pylori cause irritable bowel syndrome.
