People who do not catch a cold for a long time not only have poor immunity, but are also prone to cancer? tell you the truth

In the background, someone asked Xiao Jiu: I heard that my relatives are in good health and have not had a cold in almost several years, but they recently went to the doctor for examination and found cancer. I heard that people who do not catch a cold for a long time have poor immunity and are more likely to get cancer. is this real?

Don't worry, Xiaojiu will help you answer.

1. Is there a relationship between cancer and immunity?

A study of data from 2 million cancer patients aged 18 to 70 published in the Proceedings of the National Academy of Sciences assessed the relationship between rising cancer rates and immune system decline. The results show that the decline of the immune system plays a much greater role than expected in the occurrence and development of cancer.

At their root, cancer cells are "rebels" of normal cells and are generally killed by the immune system. When the immune system declines or has problems, some abnormal cells can "escape", and "immune decline" may become the "soil" for some abnormal cells to become tumors.

But then again, the causes of tumors are very complex, not the result of a single factor.

Does boosting your immune system prevent cancer?

It should be reminded that immunity does not equal cancer resistance . This does not mean that boosting immunity will prevent cancer. Because immunity is not the more the better, but should be in balance.

He Yumin, a professor at Shanghai University of Traditional Chinese Medicine, said that trying to fight cancer by adjusting the immune system is a beautiful theory. But the reality is that this theory has not been tested by scientific experiments, and even if there are various treatments, the actual effect is always unsatisfactory.

2. People who do not catch a cold for a long time have a worse immunity? more prone to cancer?

First of all, there is no absolute direct relationship between colds and immunity.

Some people think that people who have constant small problems and often catch colds have stronger immunity. Wang Dongxu, Department of Geriatrics, Nanjing Hospital of Integrated Traditional Chinese and Western Medicine , explained that minor illnesses such as colds can indeed mobilize immune cells to resist viruses, but it cannot be said that the so-called frequent illness can make the immune system more active.

In fact, people with frequent colds often mean that their immunity is weaker and more susceptible to illness. For example, people who often suffer from stomach pains and diarrhea easily have poor gastrointestinal function and are very likely to suffer from chronic gastrointestinal diseases. And people who don’t often catch colds or get sick with minor illnesses should have better immunity.

So why do some people usually do not get sick, but when they get sick, they are especially serious? Or even get cancer?

The main reason is that people who are often sick are more likely to notice changes in their bodies. People who are often sick are more concerned and sensitive to diseases, and more can achieve early detection and early treatment. And often communicate with the doctor, follow the doctor's orders.

Most people who are not sick usually think that they are of good quality and do not often do physical examinations, which may easily ignore the early signs of certain major diseases.

In short, people who have not caught a cold for a long time have a worse immunity? more prone to cancer? This statement is unscientific.

3. Don't want to have poor immunity, do a few small habits less

The immune system of the human body changes constantly with age. The immune system peaks around the age of 25 and gradually declines after the age of 30.

For middle-aged people, it is necessary to take good care of the immune system. Especially after the age of 40, they face more economic and mental pressure. If they treat their health like young people, it is easy to cause problems with the immune system and increase the risk of cancer. For the elderly, immunity has taken a new step, and we should also pay attention to immune disorders.

If the body has the following manifestations, it means that the immunity may be low, and you need to be vigilant.

1. The wound is not easy to heal

If even a small wound still appears red, swollen, pus and other symptoms after several days, and it is difficult to improve within a week, it may be a manifestation of low immunity.

2. Fatigue and insomnia

There is no motivation to study and work, and it is easy to feel tired. Going to the hospital for a physical examination did not find any abnormality. After a period of rest, it can be recovered, but it does not last for a long time. After a few days, the fatigue reappears , which may indicate that your immunity low force.

In addition, a weakened immune system can lead to insomnia, forgetfulness, decreased physical judgment and flexibility, and more.

3, love rotten mouth

Liang Xiong'an, chief physician of the Department of Dermatology at the Affiliated Hospital of Hainan Medical College, said that the rotten corners of the mouth may be caused by low immunity.

Rotten mouth corners, also known as cheilitis, are mainly characterized by erythema, edema, scabs, etc. at the corners of the mouth. People with poor immunity are more likely to be infected by the virus, so they have trouble with rotten mouth corners.

4. Nose likes to sweat

Pei Zhimei, chief physician of the Department of Traditional Chinese Medicine of Changchun Central Hospital, believes that this pit is a manifestation of low immunity. In the case of emotional agitation, nervousness, exhaustion, excessive activity, etc., the phenomenon of nose sweating is prone to occur. Such people may also be prone to cold problems.

Decreased immunity is not only related to aging, some bad behaviors can also destroy our immunity. If you don’t want your immune system to be weak, do these little habits less often.

One is often staying up late. A study found that compared with people who sleep 7.5 to 8.5 hours a night, people who sleep only four hours a night have 50% fewer antibodies against influenza in their bodies.

Second, the diet is irregular. Overeating, dieting, and frequent eating of fried foods and other bad eating habits may cause malnutrition and damage the body's immune system.

The third is mental stress. Feeling mental stress, depression and other emotions can affect the secretion of corticosteroids, which may have a negative impact on immunity.

Fourth, drug abuse will reduce the chance of the immune system fighting against the disease, so self-limiting diseases such as the common cold can be avoided.

Immunity does have a certain relationship with the occurrence of cancer, but people who do not catch a cold for a long time have worse immunity? more prone to cancer? The statement is biased. The immune system is the "umbrella" of the human body, and it is necessary to take good care of your own immune system.
