What blood type are you? Some people say that people with blood type A pursue perfectionism and end up with one's own end. People with blood type B love freedom and are full of motivation. People with type AB are emotional and naive. People with blood type O have open-mindedness

What are you blood type ?

Some people say that people with blood type A pursue perfectionism and end up with one end. People with blood type B love freedom and are full of motivation. People with type AB sensuality and innocence. People with blood type O have open-mindedness and goals, and do not know how to refuse...

Although it sounds magical, blood type determines personality and has not been recognized uniformly. However, scientists have confirmed that ABO blood type is related to multiple diseases. Which blood type is most likely to develop cancer?

1. Research found: Blood type B, cancer risk is low

Since the ABO blood type was discovered in 1901, blood type seems to have been closely related to the occurrence of cancer for many years.

953, people discovered that type A blood was related to the occurrence of gastric cancer . In order to understand the connection between Chinese blood type and cancer , starting from 1986, a tracking and follow-up conducted by the team of Yuan Jianmin of Shanghai Jiaotong University / University of Pittsburgh has begun.

There were more than 18,000 volunteers in the study, of which 32% belong to type O blood, 31% belong to type A blood, 27% belong to type B blood, and 10% of AB blood. In the past 20 years, a total of 3,973 people suffered from cancer, and digestive system tumors are the most common tumors, , accounting for 51% of the total cases.

study found that compared with people with type A blood, people with non-type A blood have a risk of digestive tumors reduced by about 20%;

Specifically, people with type B blood reduce the risk of gastric cancer by 25% and 22% of colorectal cancer; people with type AB blood reduce the risk of gastric cancer by 24% and 32% of colorectal cancer; people with type AB blood have no significant differences in bowel and gastric cancer in terms of intestinal cancer and gastric cancer.

②AB blood people with type AB blood have the highest risk of liver cancer , which is 42% higher than non-AB blood and 45% higher than type A blood;

, but AB and O blood can reduce the incidence of pancreatic cancer . Compared with type A blood, people with type AB blood reduce the risk of pancreatic cancer by 17%, and people with type O blood can reduce the risk of pancreatic cancer by 15%.

③ Overall, B blood type antigen is associated with a lower tumor risk. In addition to this, ABO blood type has nothing to do with the risks of lung cancer, skin cancer , prostate cancer , connective tissue tumors, and bone cancer.

2. Can blood type determine lifespan?

Why is ABO possibly related to cancer? Some scholars have put forward some hypotheses:

. Some tumor antigen structures are similar to ABO blood type antigen structures, so the antigen of these tumors may be disguised as blood type antigens to escape the recognition and attack of in human immune cells.

.ABO glycosyltransferases need to be involved in intercellular adhesion, host immune response, cell membrane signaling pathway, angiogenesis and apoptosis. If the activity of these enzymes is dysregulated, it may promote the development of cancer.

.ABO blood type antigen may affect the systemic inflammatory response, and cancer and chronic inflammation have a relatively complex relationship.

However, there is still a long way to go to study the link between various blood types and cancer. How does blood type affect cancer, and the mechanism of occurrence still needs more research.

Cancer is a joint effect of many factors, so do not judge by yourself or worry too much based on your blood type.

There are also some studies that speculate on the relationship between blood type and other diseases:

① Type 0 blood: heart disease risk, Alzheimer's low risk

In 2012, researchers from Harvard School of Public Health conducted 89,500 adults After 20 years of tracking, the results showed that people with type O blood have the lowest risk of heart disease;

In addition, researchers from the University of Sheffield performed head magnetic resonance imaging scans on 189 healthy volunteers, and then analyzed the data and found that more people with gray matter in the brain are people with type O blood, and the reduction in gray matter volume in the brain increases the risk of diseases such as Alzheimer's disease , so people with type O blood have a lower risk of Alzheimer's disease.

②AB blood type: Thrombosis is more likely to occur

Blood type is also related to the formation of thrombosis. A study published in the journal Circulation found that an important risk factor for thrombosis is AB blood type , accounting for about 20% of the cause of thrombosis.

③ Type B blood is prone to diabetes

A French study published in the journal Diabetesology. After analyzing more than 80,000 patients, people with type B blood have a 21% higher risk of diabetes than people with type O blood, which means there may be a correlation between diabetes and type B blood.

However, for the moment, the relationship between blood type and life span is still inconclusive. These studies may be affected by other factors, such as the persons participating in the survey may be population-specific or location-specific. In addition, the conclusions may be affected by factors such as methodological differences, sampling error, ethnic stratification or race.

3. Don’t count on blood types if you want to live long. It is more reliable to do these things. Instead of relying on blood types to live long, it is better to do these things well:

. Stay optimistic and have a good attitude

Bad emotions can affect the body’s metabolism and reduce immunity.

A study published in "PNAS" found that people with optimistic attitudes may live longer, even reaching 85 or older.

Therefore, we must have an optimistic and good attitude, think from multiple angles when encountering difficulties, adjust pessimistic ideas in time, and maintain a love for life.

. Stay slightly fat but not obese

In terms of longevity, people who gain slightly weight may have more advantages as they get older.

A study conducted by Ohio State University in the United States in 2020 found that people who have gradually gained weight but have not reached the level of obesity have the longest life span.

If people are already obese as adults and continue to gain weight afterwards, they have a higher mortality rate.

, healthy living habits

Professor Hu Bingchang from Harvard School of Public Health led a team to publish a research published in the journal Circulation pointed out that insists on not smoking, insisting on exercising, eating healthy diet, maintaining a healthy weight and other healthy lifestyle can greatly reduce the risk of cancer and cardiovascular diseases and extend the life expectancy after 50 years of age by more than 10 years.

. Participating in social activities

Social activities will also have a certain impact on lifespan. Social activities can not only increase the sense of identity, but also reduce the feeling of loneliness and reduce the risk of Alzheimer's disease and depression.

A previous study in Social Sciences showed that positive social relationships and a 50% increase in survival rates were associated with a 50% increase in people with social isolation, and people with 29% increased risk of cardiovascular disease and 32% risk of stroke.

In short, there may be a relationship between blood type and some diseases, but if you want to live a long life, you need not rely on blood type. Get rid of bad habits and a healthy life is more important.
