If you have a certain blood group, you are more likely to develop a certain cancer, suggest a study quoted by the Daily Mail. One theory is that different blood groups produce different responses of the immune system to threats such as bacteria.

Research shows that people with blood group A, B or AB may be much more likely to develop certain types of lethal cancer.
Those who have a negative or positive blood group could be somewhat protected from pancreatic cancer, which has the highest mortality rate of all common cancers.
A recent study on 50,000 Iranians showed that those with blood group A, B or AB have a 55% higher risk of developing stomach cancer, compared to group 0.. The same study concluded that people with blood group are also with a more prone to intestinal cancer.
According to another study, conducted in 2016 on nearly 18,000 adults, people with AB blood group have a 45% higher chance of developing liver cancer. The study also indicated that people with blood groups 0 and AB have a risk of about six times lower to develop pancreatic cancer.
Specialists cannot say exactly why certain blood groups have an increased risk of cancer, especially those that form in the digestive tract. According to one of the theories, different blood groups produce different responses of the immune system to threats such as bacteria, triggering changes in cells that increase the risks of cancer.
However, some experts have appealed to caution regarding the interpretation of the connections between the blood and cancer group, stressing that, in general, the number of participants in studies is small, and research does not take into account other factors that increase the risk of cancer, such as alcohol consumption or smoking.
We recall that a study published in Neurology magazine showed that people with one of the type A blood groups have more risks to suffer a stroke before the age of 60, compared to people with other blood groups.
“The blood groups are genetically inherited from parents to children”
The blood groups were identified by the American Karl Landsteiner, in 1900, and the discovery brought the Nobel Prize for Medicine.
Initially, he identified only the A, B and 0 groups, but later he discovered the fourth type of blood, AB.
“The letters symbolize two antigens (substances that can be attacked by the immune system) called A and B. The blood group A has only the antigen A; the blood group B has only the antigen b; the group AB has both; group 0 has no one”, According to the website of the National Center for Blood Transfusion.
Blood groups are genetically inherited from parents to children.
In Romania, blood groups are distributed as follows: 43% – group A, 33% group 0, 16% – group B and 8% group AB.
It is known that blood cannot be donated to anyone, but there must be a compatibility between people. Those with group 0 are also called universal donors because they can donate to everyone, but they can only receive blood from people with the same group.
People in the AB+ group can only donate blood to the same type of group, but they are universal recipients, in the sense that they can receive blood from any group.
