The American Cancer Society says that people with type A blood have a “higher risk of getting stomach cancer.” Many studies have confirmed this, one of the most recent being a 2017 study published in PLOS One. According to this study, individuals with blood type A have a 26 percent increased risk of stomach cancer when compared to those that have blood type B and O.

The 2017 study found that when compared with blood type A, non-A blood types had a 20 percent lower risk of cancer in the gastrointestinal tract, specifically both stomach cancer and colorectal cancer. According to the researchers, similar to stomach cancer, those with blood type A experienced a “significantly increased risk of colorectal cancer” compared to those with a non-A blood type.

The American Cancer Society says that while type A blood is associated with an increased risk of stomach cancer, the reasons are “unknown.” However, experts at WebMD say that many researchers have theorized that this could be because H. pylori infection is more common in people with type A blood. This type of infection is caused when the bacteria Helicobacter pylori (H. pylori) enters your body and stays in your digestive tract. “After many years, they can cause sores, called ulcers, in the lining of your stomach or the upper part of your small intestine. For some people, an infection can lead to stomach cancer,” WebMD explains.

And per a 2017 report from the Centers for Disease Control and Prevention (CDC), survival rates for this cancer are low. The one-year survival rate is estimated at 53.1 percent, while the three-year and five-year survival rates were estimated to be only 33.8 percent and 29 percent, respectively. This is much lower than other types of cancer, like kidney cancer, which has a five-year survival rate of 75 percent; thyroid cancer, which has a five-year survival rate of 98 percent; and even brain cancer, which has a five-year survival rate of 35 percent, per data from the American Cancer Society.
