According to Swedish scientists, blood type can influence the predisposition to developing cancer. Such studies appear in journals from time to time.
In the work, which lasted more than 25 years, experts studied thousands of medical records, comparing the diagnosis and blood type of their owners.
Experts claim that people with the second blood group are more successful than others in preventing the development of cancer by maintaining a healthy lifestyle.
A study by American scientists notes that people with the second blood group have an increased risk of developing stomach cancer.
With the third and fourth blood groups, malignant tumors most often develop in the pancreas. And people with the first blood group get cancer less often than others. They are more susceptible to gastritis, stomach ulcers and other gastrointestinal problems.
Chinese doctors noted that the most favorable prognosis for stomach cancer is in people with the fourth blood group. And the worst is with the second.
In general, blood group should not be considered a death sentence, since the advantages in relation to some diseases are offset by the increased risk of others, experts admitted.
Scientific studies have not revealed a clear relationship between blood type and susceptibility to contracting acute respiratory viral infections. However, some studies show that people with different blood types may have different levels of susceptibility to certain infections. It is noted that people with the first blood type may be more susceptible to influenza viruses.
Cardiologist Vladimir Podkhomutnikov previously noted that people with the first and third blood groups tolerate vaccinations worse than others. The first group is characterized by high sensitivity to vaccinations, and its owners may experience fever, irritability, and lethargy in the first three days after vaccination.
People with the second group have sensitive stomachs and intestines, so vaccination can cause a negative reaction.
People with the third blood group often have a bad reaction to vaccinations, just like people with the first. People with the fourth group usually do not have negative reactions to vaccinations, but they are also not recommended to receive oral vaccines.
