Using large population surveys, Tufts University researchers found that certain blood types are associated with a higher risk of heart attacks or strokes and certain types of cancer.

Blood is divided into different groups, depending on the presence of antigens on the surface of red blood cells. The two most important antigenic systems, from a clinical point of view, are the ABO system and the Rhesus (Rh) system.

The ABO system determines whether the blood group is A, B, AB or O. Blood type is determined by the presence of antigens on the surface of red blood cells and the corresponding antibodies in the plasma.

On the website of the National Blood Donation Center we read that each person belongs to one of eight blood groups. These groups are subgroups of the four main groups of the ABO system – A, B, AB or O.

The Rhesus (Rh) system further divides these four groups into Rh positive (+) or Rh negative (-), creating eight basic blood types. types or groups: O, O+, B-, B+, A-, A+, AB- or AB+. The most common blood type is O+ and the rarest is AB-.

CANCER:

Research shows that people with blood type A are at a higher risk of developing certain types of stomach cancer. Bacterial infections from E. pylori are more common in patients with blood type A and these infections can cause stomach ulcers, inflammation and sometimes lead to cancer, Professor Comenzo points out. Helicobacter pylori (E.pylori) may also be associated with higher rates of pancreatic cancer in blood types A, B and AB.

These three blood groups can also affect the risk of other cancers. "For patients with blood group A, B or AB, the ABO gene may also play a role in increasing the risk of certain cancers, particularly of the lung, breast, colon and cervix," explains Professor Comenzo. But researchers still aren't sure how these types of cancer are related to blood type.

CARDIOVASCULAR DISEASES:

Blood types A, B and AB are associated with a higher risk of heart attack. Due to coronary heart disease than blood type O. In particular, people with blood type AB appear to be at higher risk. These blood types have also been associated with higher rates of blood clotting disorders.

STROKE:

People with blood type A were slightly more likely to have a stroke before age 60. Than people with blood type O.

MOSQUITOES:

In laboratory experiments, mosquitoes seem to "prefer" people with blood type O. Although other genetic factors play a role.

CORONAVIRUS:

Patients with blood type O had a slightly lower risk of dying from COVID-19. Experts emphasize that these findings do not apply to individuals and therefore should not cause concern. These are data on how diseases are managed at the population level.
