5 Things your blood type says about you – Make sure you see this!

2. Stomach Cancer

More bad news if you’re blood type AB: Your risk for stomach cancer is roughly 26% higher than if you had blood type B or O, concludes a study from the American Journal of Epidemiology.

A kind of bacteria called H. pylori may be to blame. While roughly two-thirds of the world’s population are walking around with H. pylori in their guts, those with blood type AB or A may have a heightened immune system reaction to the bacteria that increases their cancer risk, says study coauthor Gustaf Edgren, MD, PhD, an epidemiologist at Karolinska University Hospital in Sweden.
