United States: Disease experts have found that persons with blood types A, B, or AB face significantly increased possibilities of developing different fatal cancer types.
People who fall under type O negative or positive blood group expression variation allow them to have some resistance against lethal pancreatic cancer.
What are the experts indicating?
Stomach cancer incidence among Iranians increased by 55 percent when A, B, and AB blood types compared with O blood types.
People with A blood show a 16% higher chance of developing bowel cancer based on research findings. Research from 2016 about 18,000 adults showed individuals with AB blood type faced a 45% elevated risk for liver cancer development.
People with O or AB blood exhibited pancreatic cancer risk levels 16.6 percent below the baseline, according to research findings, Daily Mail reported.
British citizens mostly possess O-positive blood, with their blood type distribution extending to A positive and A negative.
The demographic of individuals possessing AB-negative blood type stands at a low share of one percent among British citizens.
Why does this happen?
Scientific experts have not found definitive explanations for why blood types become more susceptible to digestive tract cancers or other cancer types.
Immune responses from various blood types to bacteria create cell alterations, which make cancer more likely to develop.
Some medical experts caution against the interpretation of blood type relations with cancers despite these reported associations between them, Daily Mail reported.
The researchers pointed out that published studies typically use limited numbers of participants and ignore various cancer risk factors such as alcohol consumption and smoking behavior.
Each of the four blood groups possesses two secondary subgroups that include positive and negative factors, while O+ and A+ represent the most prevalent types.
