As early as the 1950s and 1960s, researchers noticed that ABO blood type may have a close relationship with cancer.

Norwegian Scholars studied a total of 3053 patients with cancer (lip cancer, tongue cancer , esophageal cancer, gastric cancer and breast cancer ). The results showed that there was no obvious correlation between ABO blood type and cancer. In 1964, this research result was published in the internationally renowned medical journal "The Lancet".

However, this negative result did not extinguish the researchers' enthusiasm for continuing to explore the relationship between the two.

In recent years, there have been many researches on blood type and cancer. So what is the truth? Is it metaphysics or science to predict cancer risk when blood type predicts? Let’s take you to have a look today. Which blood type is more likely to develop cancer in

?

——Type A blood

A large sample size study covering 30 countries spans 60 years, including about 100,000 cancer patients and 30 cancer sites, showed that the risk of cancer in blood type A is 1.12 times that of other blood types, among which women with blood type A are more likely to develop cancer.

Specifically, breast cancer (12%) and ovarian cancer (16%) have a large proportion of the occurrence of two common tumors in women.

—B blood

Overall, compared with blood type A, the risk of most cancers in Chinese blood type B population is lower, especially gastric cancer and colorectal cancer.

In addition, the relationship between blood type B and bladder cancer risk has not yet been concluded, but men with blood type B have a lower risk of bladder cancer, while blood type B is associated with an increased risk of prostate cancer . The conclusion that

and AB blood type is consistent with that of AB blood type , is that the risk of epidermoid cancer in people with blood type B is not related to the risk of cancer in sarcoma , lymphoma , and leukemia .

——AB blood

Generally speaking, men with AB blood type have a higher risk of cancer.

Chinese population AB blood type is associated with an increased risk of liver cancer . AB blood type is not associated with the risks of sarcoma, lymphoma, and leukemia, but AB blood type is at a lower risk of epidermoid and adenocarcinoma. In terms of digestive tract tumors, the study on the risk of AB blood type and gastric cancer has reached completely different conclusions, but the risk of AB blood type to colon cancer is significantly reduced.

AB blood type may also indicate better clinical outcomes in colon cancer patients, with an average overall survival of higher patients than non-AB blood type. However, the survival rate of ovarian cancer patients is low

——O blood

O blood people have a better advantage over other blood types. O blood is the universal blood in everyone's mind, but not all blood types can be infusion. You still need to pay attention to pairing. Because people with O blood are more active, their metabolism abilities are relatively good, and they can regulate their bodies in time.

Compared with other blood types, people with type O blood have a lower risk of cancer, and people with type O blood are generally positive and optimistic, and they can regulate their emotions in a timely manner.

blood type predicts cancer risk. Is it metaphysics or science?

Scientists are also interested in this issue.

A study found that among the 125 healthy men aged 65-89, the proportion of type A blood was higher. But later, similar research has not yet concluded. For example, a survey of 269 centenarians in Japan found that type B blood accounts for the largest proportion; for example, the US research conclusion is exactly the opposite, and it is believed that type B blood is a sign of early death.

At present, the relationship between blood type and lifespan is inconclusive. Since ABO blood type is an unchangeable characteristic of humans, these research results may be attributed to "quite interesting" facts, rather than "clinical practical".The emergence of cancer is also related to many factors. It cannot be judged by blood type alone, but should also be comprehensively judged based on lifestyle habits, eating habits, genetic factors, etc.

Although many studies have found that blood type is related to lifespan, instead of worrying that they will get sick, it is better to intervene in acquired factors as soon as possible, which is more important.

How to prevent cancer in life?

. Balanced mentality, mental health

WHO defines mental health as: "not only does not have mental illness, but also can correctly understand one's own abilities, cope with normal life pressure, fruitful work, and a good state that can help others."

There are five criteria for evaluating mental health, one is normal intelligence; the second is good mood; the third is harmonious interpersonal relationships; the fourth is adapting to the environment; and the fifth is complete personality.

. Stay away from cancer-causing foods

Most people prefer high-calorie and high-fat foods. Red meat has been listed as a Class 2A carcinogen, which means eating too much red meat can increase the risk of cancer.

Eating too much pickled food can also increase the chance of cancer, especially Chinese-style salted fish have been listed as a type of carcinogen. In addition, you cannot eat foods above 65℃ and beverages containing alcohol. The former can induce esophageal cancer, while the latter can cause liver cancer.

. Maintain normal weight

Body weight index is a number obtained by dividing the weight kilograms by the square of meters of height. When the BMI index is 18.5 to 24.9, it is a normal healthy weight. Below 18.5 is a low weight, 25 to 29.9 is overweight, and greater than and equal to 30 is severely overweight or obese. It is recommended to keep your weight within the minimum value within the healthy BMI range.

4. Physical examination and prevention of cancer

Many tumors are gradually evolved from some chronic diseases. Through regular physical examinations, early intervention can be achieved. Timely and effective treatment can not only remove precancerous lesions , but also completely cure some early tumors.
