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

Someone asked Xiaojiu in the background: I heard that my relative is in good health and hasn't had a cold for almost a few years, but recently went to the doctor for an examination and was found to have cancer. It is said that people who have not caught a cold for a long time have poor immunity and are more likely to get cancer. is this real?

Don't worry, Xiao Jiu will help you answer.

1. Is there a big relationship between cancer and immunity?

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

In essence, cancer cells are the "rebellion" of normal cells and are generally killed by the immune system. When the immune system declines or problems occur, 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.

Is it possible to prevent cancer by improving immunity?

What needs to be reminded is that immunity is not equal to cancer resistance . This does not mean that improving immunity will definitely 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 immunity is a very good theory. But the reality is that this theory has not been tested by scientific experiments. Even if there are various treatments, the actual effect is always unsatisfactory.

2. People who have not caught a cold for a long time have weaker immunity? More prone to cancer?

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

Some people think that people with constant minor illnesses and frequent colds have stronger immunity. Wang Dongxu from the Geriatrics Department of 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 who often catch colds often mean that their immunity is weaker and they are more likely to get sick. For example, people who often suffer from stomach pains and are prone to diarrhea have poor gastrointestinal function and are likely to suffer from chronic gastrointestinal diseases. People who don't often catch colds or suffer from minor illnesses should have better immunity.

Then why are some people who don't usually get sick, but are particularly serious when they get sick? Or even get cancer?

The main reason may be 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 they are more likely to achieve early detection and early treatment. And often communicate with the doctor, follow the doctor's orders.

People who don't get sick usually think that they are of good quality and don't do physical examinations often, so it may be easy to ignore the early signs of some major diseases.

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

3. If you don’t want to have poor immunity, do a few small habits less

The body's immunity changes with age. The immune system reaches its peak 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, when they face more economic and mental pressures. If they treat their health carelessly like young people, it is easy to cause problems with the immune system and increase the risk of cancer. Elderly people, whose immunity has dropped to a new level, should also pay attention to immune disorders.

If the following manifestations appear in the body, it means that the immunity may be low, and vigilance is required.

1. The wound is not easy to heal

If symptoms such as redness, swelling, and pus still appear after many days even for a small wound, and it is difficult to improve within a week, it may be a sign of low immunity.

2. Fatigue and insomnia

I have no motivation to study and work, and I feel tired easily. I went to the hospital for a physical examination and found no abnormalities. I can recover after a period of rest, but the duration is not long. The fatigue reappears after a few days . This may imply your immune system. Power is low.

In addition, low immunity may also lead to insomnia, forgetfulness, decreased body judgment and flexibility, and so on.

3. Love the rotten corners of the mouth

Liang Xiongan, 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 corners of the mouth, also known as angular cheilitis, are mainly manifested as erythema, edema, and scabs at the corners of the mouth. People with poor immunity are more likely to be infected by viruses, so they are troubled by rotten corners of the mouth.

4. The nose loves 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. Sweaty noses are prone to occur in situations such as emotional excitement, mental stress, fatigue, excessive activity, etc. Such people may also be prone to colds

Declining 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, these little habits should be avoided.

One is to often stay up late. Studies have found that compared with people who sleep 7.5 to 8.5 hours a night, people who sleep only four hours a night will have 50% fewer antibodies against influenza.

The second is irregular diet. Bad eating habits such as overeating, dieting, and often eating fried foods 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, etc., which may have a negative impact on immunity.

The fourth is drug abuse. Drug abuse will reduce the chances of the immune system to fight against diseases. Therefore, self-limiting diseases such as the common cold can avoid medication, and if acute influenza and other diseases that the autoimmune system cannot resist occur, timely diagnosis and treatment is required.

Immunity does have a certain relationship with the occurrence of cancer, but people who have not caught a cold for a long time have worse immunity? More prone to cancer? statement is biased. The immune system is the "protective umbrella" of the human body, so we must take good care of our own immune system.
