A recent study conducted in London, England has found a potential link between certain blood types and an increased risk of developing specific types of deadly cancers. The research suggests that individuals with blood types A, B, or AB may face a higher likelihood of developing certain types of cancer, while those with type O blood may have some level of protection against certain varieties of deadly cancers. For instance, the study revealed that individuals with blood types A, B, or AB have a 55% higher risk of developing stomach cancer compared to those with type O blood. In addition, people with type A blood have a 16% higher risk of bowel cancer.
On the other hand, individuals with O and AB blood types were found to have a lower chance of developing pancreatic cancer, with a one-sixth decrease in risk. The study also showed that those with AB blood types had a 45% higher chance of developing liver cancer. Experts are currently unsure about the exact reasons behind the correlation between blood types and cancer risk, but one theory suggests that different blood types may trigger varying immune responses that could influence the likelihood of cancer development.
It is worth mentioning that participant numbers in these studies are often limited, and they may not always consider other factors that can contribute to cancer risk, such as alcohol consumption or smoking. Despite these findings, researchers urge caution in interpreting the relationship between blood types and cancer risk. Blood type is a genetic trait inherited from parents and cannot be altered. Individuals can determine their blood type through a simple procedure called ABO typing, which involves analyzing a small blood sample. Various methods, including DIY tests available online or blood tests at private clinics, can disclose one’s blood type.
In the United Kingdom, the most common blood types among blood donors are O positive and A positive, which together make up around 65% of the population. The NHS Blood Donation program also informs donors of their specific blood type after their initial donation. By understanding their blood type, individuals may gain insights into potential health risks associated with specific blood types and take proactive measures to mitigate these risks.
