Are there many cases of nasopharyngeal carcinoma recurrence? How to prevent recurrence?

1. Radiotherapy is very effective for patients with early-stage nasopharyngeal carcinoma. The five-year survival rate of nasopharyngeal carcinoma can reach more than 90%. The effect of radiotherapy alone is poor in the middle and late stages, and the five-year survival rate is only about 50%. In order to reduce the recurrence rate and the rate of distant metastasis, patients in the middle and late stages often receive chemotherapy.

2. Radiotherapy kills cancer with first-order kinetics of exponential killing, that is, the radiation therapy dose can only kill a certain proportion of cancer cells in the tumor. According to the rules of killing cancer, no matter how many times it is exposed, a small amount of cancer cells will remain. The number of cancer cells that remain depends on the size of the radiation therapy dose. Although a small number of cancer cells remain after radiotherapy, people have resistance. The white blood cells in the body can recognize and kill foreign cells, senescent cells or malignant cells. The survival and division abilities of cancer cells treated with radiotherapy are very poor.

3. Nasopharyngeal cancer is generally considered cured after 5 years. However, the chance of a second recurrence of nasopharyngeal cancer is relatively high, and many of them are other parts of the body such as lung cancer. The correct attitude is not to be too nervous, but also not to take it lightly.

4. Only by strengthening the body's immune defense function can the body clear or inhibit residual cancer cells in the body and truly prevent recurrence and metastasis. Diet therapy is very important for preventing and treating the recurrence of nasopharyngeal carcinoma. Diet therapy is to enhance the patient's immunity and recovery ability through dietary adjustment; family members encourage patients to eat and give them high-protein, high-vitamin, low-fat, easily digestible foods. Such as beans, milk, fungi, carrots, etc. Pay attention to the color and aroma of the diet, provide patients with delicious food, and provide patients with rich nutrition. It is also very important to prevent and treat the recurrence of nasopharyngeal carcinoma. We should always maintain an optimistic attitude.
