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, which persisted, and 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 subsequently underwent a lymph node biopsy and was considered “at risk for malignancy.”
After physical examination, the doctor found Ms. Yan’s an abnormal mass in her left breast, and the MRI results showed that the diameter of the lesion was about 3.5cm, which was highly suspected 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 people have at birth. Acquired immunity refers to the immune system formed by continuous exposure to pathogens (such as bacteria, harmful substances, etc.)
Outside, the immune system protects against 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 homeostasis ability to continuously remove damaged, senescent and dead cells from the body to maintain the vitality of the body.
However, it should be noted that the immune system cannot provide permanent protection, and it may still be defeated when it encounters an unfamiliar pathogen.
Second, if you don’t have a cold and fever for a long time, and your immune system is poor, are you more likely to get cancer?
Jiansheng 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 only extremely Few, individual cases.
As early as 1986, some scholars conducted a survey on “the correlation between colds and cancer”, and the study compared the cold situation in the past 10 years in cancer patients and non-cancer patients , it was found that 41.7% of cancer patients had less than one cold per year compared with 33.5% of non-cancer patients, but there was a statistically no significant difference.
Then why is it that someone who never catches a cold is suddenly diagnosed with a serious illness?
From clinical experience, the possible reason is ignoring mild symptoms and infrequently going to the hospital.
People who often catch 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 a mild cough and fever, don’t care about minor symptoms, and when they have to go to the hospital, the probability of getting sicker increases.
Third, a habit can enhance immunity and develop “anti-cancer constitution”
A good habit can enhance immunity and develop “Anti-cancer constitution”?
Research tells you: The 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 >, which is a “secret weapon” with the ability to inhibit tumor growth.
Study author Professor Robert said that myokines can send signals to the immune system to create a “tumor suppressor environment” in the body and slow the growth of cancer cells. He also speculates that the myokine may be effective against all forms of tumors.
Fourth, these three kinds of sports exercise are better
We all know that exercise can enhance physical fitness , but which exercise works best, do 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, swimming and aerobics, 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., which consume a lot of energy, can exercise the muscles of the whole body, regulate eye movement, Accelerates blood circulation and metabolism in tissues, thereby increasing body sensitivity. In addition, swinging sports can also promote the brain to think quickly, play a role in strengthening the brain and delaying cognitive aging.
Swing sports are suitable for people of all ages. Among them, table tennis and badminton with lower intensity 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 do 3-5 times swinging exercises per week, and each exercise time should be 30-60 minutes.
2. Swimming
Swimming can exercise the whole body, improve cardiopulmonary function and blood circulation, relieve stress and regulate mood. Blood pressure, hyperlipidemia, diabetes, obesity, arthritis and other diseases have obvious preventive and rehabilitation effects.
Swimming is suitable for people of all ages, but if you have severe 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 and help stabilize Blood pressure, blood sugar and blood lipids, improve myocardial antioxidant capacity, enhance immune function, and improve weight loss effect. 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.
