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

Ms. Jiang (pseudonym) is 43 years old. She likes sports and lives a regular life. She has not had a cold or fever for nearly ten years.

Not long ago, Ms. Yan suddenly had a cold and fever, and the high fever persisted. She went to the hospital for treatment. Due to the needs of epidemic prevention and control, Ms. Yan underwent a CT examination, and the results showed that "the lungs were normal ", but there was " swollen lymph nodes in the armpit ".

She then had a lymph node biopsy , which was considered " at risk of malignancy ".

After a physical examination, the doctor found that Ms. Yan had an abnormal mass in her left breast . The MRI results showed that the diameter about 3.5cm , which was highly suspected of breast cancer. After the pathological diagnosis, Ms. Yan received breast-conserving surgery and neoadjuvant therapy, and the lesion was reduced to 0.02cm. She is still undergoing intensive treatment to consolidate and improve the curative effect.

At one time, Ms. Yan did not believe in the saying that "long-term absence of a cold is more likely to lead to cancer", but after this experience, she began to believe it .

1. How strong is the human immune system?

The immune system can be divided into innate immunity and acquired immunity (also called acquired immunity) .

Innate immunity refers to the immunity that a person has at birth. It is the earliest defense mechanism of the body and has a defense effect against a variety of germs. Acquired immunity refers to the immune system formed by continuous exposure to pathogens (such as bacteria, harmful substances, etc.) in the day after tomorrow.

Externally , the immune system can prevent the invasion of foreign bacteria and germs. Internally , the immune system acts as a " monitor " to identify and remove abnormal cells in the body, such as cancer cells, in a timely manner. In addition, the immune system has the ability to self-stabilize , constantly removing damaged, aging and dead cells from the body to keep the body alive.

But it should be noted that the immune system cannot provide permanent protection , and it may still be defeated when encountering unfamiliar pathogens.

2. If you don’t have a cold for a long time and have a fever for a long time, are you more likely to develop cancer due to poor immunity?

Jie Jiang, a research associate professor at the Department of Pathology and Experimental Medicine, said that clinically, it is true that people who have not been sick for a long time suddenly develop cancer, but it is only a very small number and it is a case .

As early as 1986, some scholars conducted a survey on the correlation between colds and cancer. The study compared the colds of cancer patients and non-cancer patients in the past 10 years . The results found that cancer patients with less than one cold per year had 41.7% and 33.5% of non-cancer patients, but they were not statistically significantly different .

So why is it that someone who never catches a cold is suddenly diagnosed with a serious illness?

From clinical experience, the possible reason is neglect of mild symptoms and infrequent visits to the hospital .

People with frequent colds tend to be more sensitive to symptoms, receive more tests, and are more likely to catch the disease at an early stage. And those who never catch a cold may ignore the slight cough and fever, and do n't pay much attention to the mild symptoms of the body. When they have to go to the hospital, the probability of exacerbation also increases.

3. A habit to enhance immunity and develop an "anti-cancer physique"

Doing a good habit at ordinary times can enhance immunity and develop an "anti-cancer physique"?

Research tells you: this habit is to keep exercising.

A study published in Sports Medicine & Science found that exercise not only improves overall health, but also causes the body to release a myokine , a "secret weapon" that has the ability to inhibit tumor growth.

Study author Professor Robert said myokines could signal the immune system to create a " tumor suppressor environment " in the body, slowing cancer cell growth . He also speculates that the myokine may be effective against all forms of tumors.

Fourth, these three kinds of sports exercise better

We all know that exercise builds our physique, but what kind of exercise works best, you know?

The authoritative medical journal "The Lancet" published a survey involving 1.2 million people to analyze the impact of different sports on human physical and mental health. The results showed that the top three sports were swing sports, swimming and aerobic exercise , which reduced all-cause mortality by 47%, 28% and 27%, respectively.

These three sports have their own advantages and are suitable for different groups of people. You can choose the one you like.

1. Swing sports

Including table tennis, badminton, tennis, etc., consumes a lot of energy, can exercise the muscles of the whole body, adjust the eye movement, speed up the blood circulation and metabolism of the organization , thereby improving the sensitivity of the body. In addition, swinging sports can also promote the brain to think quickly, play a role in strengthening the brain and delaying cognitive aging.

People of all ages are suitable for swing sports. Among them, table tennis and badminton with lower strength and less confrontation are more suitable for the elderly , and strength sports such as tennis and squash are more suitable for young people.

It is recommended to perform swinging exercises 3-5 times a week , and the duration of each exercise should be 30-60 minutes .

2. Swimming

Swimming can exercise the whole body, improve cardiopulmonary function and blood circulation, relieve stress and regulate mood. It has obvious preventive and rehabilitation effects on cardiovascular and cerebrovascular diseases, hypertension, hyperlipidemia, diabetes, obesity, arthritis and other diseases.

Swimming is suitable for people of all ages, but if you have serious cardiovascular and cerebrovascular diseases , you should avoid them, such as coronary heart disease, more serious arrhythmias, rheumatic valve disease, etc. It is recommended to do swimming exercise 2-3 times a week, each time of about 30 minutes is appropriate.

3. Aerobic exercise

Aerobic exercise can exercise cardiopulmonary function, help stabilize blood pressure, blood sugar and blood lipids, improve myocardial antioxidant capacity, enhance immune function, and improve weight loss. Common aerobic exercises include brisk walking, jogging, cycling, aerobics, tai chi, etc.

Aerobic exercise is also suitable for people of all ages , especially those who are overweight and obese. It is recommended to do at least 150-200 minutes of aerobic exercise per week, divided into 3-5 times.

In general, not getting sick for a long time does not mean that we are " holding back " a serious illness. We must do a good job of health care in daily life, strengthen our immunity, and check our bodies in time to detect diseases as soon as possible.
