If you have a certain blood type, you’re MORE likely to develop cancer, research suggests

ByMike Anderson

Recent scientific studies have identified potential links between specific blood types and an increased susceptibility to certain forms of cancer. This research suggests that an individual’s blood group could influence their risk of developing malignancies, particularly within the digestive system.

One study, which analyzed data from 50,000 individuals in Iran, indicated that people with blood types A, B, or AB may face a heightened risk. The findings proposed that these groups have a 55 percent higher chance of developing stomach cancer compared to those with other blood types.

The same research also highlighted a significant risk for bowel cancer. It concluded that individuals with type A blood were six times more likely to be diagnosed with this form of cancer than people with other blood classifications.

A separate study from 2016, involving 18,000 adults, focused on liver cancer. It found that participants with the AB blood type had a 45 percent increased risk. Conversely, those with types O and AB appeared to have a lower risk for this particular cancer.

Scientists do not yet fully understand the biological mechanisms behind these correlations. One prevailing theory suggests that different blood types may trigger varied immune responses to bacteria and viruses, potentially leading to cellular changes that promote cancer growth.

However, medical experts advise caution when interpreting these findings. They note that many studies have small sample sizes and often do not account for other major risk factors, such as lifestyle choices including smoking and alcohol consumption.

For those wishing to learn their blood type, several options are available. These include at-home test kits, private clinic services, and free identification for first-time blood donors through the NHS. A person’s blood type is genetically inherited and remains fixed throughout their life.
