? What is immunotherapy?A
For malignant tumors, immunotherapy is an advanced medical technique beyond traditional surgery, chemotherapy, and radiation therapy. Conventional surgical treatments may be limited when the tumor's location is not suitable for surgery (such as blood cancer and brain cancer) or when existing diagnostic technologies cannot detect the presence of cancer cells. Radiation therapy and surgery share similar limitations, targeting patients with localized and identifiable tumor locations. While chemotherapy can overcome some limitations of surgery and radiation therapy, non-specificity of chemotherapy drugs may lead to side effects by attacking normal cells, compromising the patient's immune system, and potentially causing drug resistance in cancer cells with prolonged use. Immunotherapy, utilizing the patient's own immune cells, is considered a method that may address the shortcomings of traditional surgery, chemotherapy, and radiation therapy.
? When is the optimal time to store immune cells?A
Besides genetic factors and environmental influences, age is the most significant factor affecting immune function. The body's immune system peaks at the age of 20, and as age increases, the inevitable aging process results in a gradual decline in immune function. At 40 years old, immune function is only half of its peak, and by 70 years old, it may be reduced to one-tenth. By 80-90 years old, immune function is almost entirely lost. Therefore, storing immune cells is best done as early as possible.
? Why store immune cells?AAs age increases, the immune system weakens, making individuals more susceptible to various diseases. Modern lifestyles, characterized by high stress levels, irregular diet, and disrupted sleep patterns, contribute to weakened immune systems, increasing the risk of diseases. Storing young and healthy cells in advance allows for future infusion into the body when needed, enhancing resistance and combating diseases.
? Why store cells now? Can't we wait until we get sick to draw blood for cultivation?A
The immune system's peak (primarily T-cell types) is reached at 18-20 years old. By the age of 40, it's only half of the peak, and by 70, it's only one-tenth of the peak. Additionally, immune cells are more capable and active when the body is healthy compared to when it is sick. When sick, the body requires healthy and capable cells to assist in defending against diseases. Therefore, now, when you are healthy, is an ideal time to store cells. Before storing immune cells, it's advisable to undergo a health check, as the outward appearance alone cannot determine overall health.
? Can children or elderly individuals store immune cells?A
For children, it is generally recommended to wait until after the age of 18 to perform cell storage. Before 18 years old, the body's development may not be complete. For elderly individuals, storing immune cells is possible because today is always younger than tomorrow. Young cells are healthier compared to aging cells.
