In our daily lives, fever is often seen as a natural response of the body to the invasion of disease, and many people even believe that people with frequent fevers are in good physical condition and have a strong immune system. Do people who have not had a fever for a long time have weak immunity and are more susceptible to cancer?
Medical Principles of Fever. Fever is actually a self-protection mechanism of the body's immune system in response to the invasion of foreign pathogens (such as bacteria, viruses, etc.). Pathogen invasion, immune activation, release cytokines and inflammatory factors, body temperature rises to prevent pathogen breeding. Elevated body temperature is actually a sign of active immune mechanism, not the root cause of disease.
For those who have not had fever for a long time, is their immunity really weak? The answer is no. Each person's immune system has its own unique way of working and sensitivities. Some people may have a less sensitive immune system to pathogens due to genetic factors, lifestyle habits, environmental factors, etc., so they are not prone to fever. But that doesn't mean their immunity is necessarily poor. In fact, the strength of immunity is a comprehensive assessment, including the number, activity, diversity and other aspects of immune cells. Fever is only one of the indicators, and it cannot be used alone to judge the strength of a person's immunity.
The relationship between cancer and fever, immunity. Cancer has many causes, including genetics, environment, and daily habits. Although studies have shown that immune status is associated with cancer development, immunodeficiency is not the sole or absolute cause of cancer. Because the occurrence of cancer involves the regulation of many links, and the immune system is only one part of it. Even if people with weakened immunity are more susceptible to pathogens, it doesn't mean they're necessarily more susceptible to cancer. The occurrence of cancer is a long-term and intricate process, which requires the synergy of multiple factors.
To better understand the problem, let's look at a vivid case. Mr. Zhang rarely has a fever every day, and his body seems to be strong and sound. At the time of the physical examination, Mr. Zhang was diagnosed with lung cancer. This made Mr. Zhang very confused, he felt that he rarely got sick, how could he suddenly get cancer? In fact, Mr. Zhang's example is not unusual. Many cancer patients have no obvious symptoms before the onset of the disease, and the occurrence of cancer is often related to a variety of factors, not just the strength of immunity.
Of course, we cannot ignore the role of immunity in cancer prevention and treatment. A strong immune system can detect and remove abnormal cells from the body in a timely manner, thereby reducing the risk of cancer. Maintaining a healthy lifestyle, a balanced diet, and moderate exercise are all very helpful in improving immunity. Immunotherapy is also one of the important treatments for patients who already have cancer. By activating the patient's own immune system to attack tumor cells, the goal of cancer treatment is achieved.
People who do not have a fever for a long time do not necessarily have poor immunity, nor does it mean that they are more susceptible to cancer. The strength of immunity is a comprehensive assessment that requires a combination of factors. The occurrence of cancer is also a complex process that requires the combined action of multiple factors. We can't simply link fever, immunity, and cancer. We should maintain a healthy lifestyle, a balanced diet, and moderate exercise to improve our immunity and thus reduce the risk of cancer. At the same time, regular physical examinations and screenings are also carried out to detect and treat potential health problems such as cancer in a timely manner.
