There is a 60% recurrence rate of pituitary tumors after surgery, mainly because pituitary tumors are aggressive tumors that do not have intact borders after emergence. Combined radiotherapy after surgery for pituitary tumor treatment is more effective, which can greatly reduce the recurrence rate of the disease. The main reasons for the recurrence rate of pituitary tumor are as follows: 1. During the operation, the tumor is not completely removed or the operation is incomplete, and the residual tumor cells and tissues in the patient’s body can cause the tumor to grow again if the patient does not have any auxiliary treatment after the operation; 2. Pituitary tumor cells in the patient’s body appear to be proliferating; 3. The patient’s tumor appears to be invasive and grows after the operation, and there are also the problems of dura, cavernous sinus and so on; 4. If the patient himself belongs to multiple pituitary tumors, it is also an important reason for the recurrence of pituitary tumors. Patients need to pay attention to reduce the chance of recurrence caused by their own problems in the future, actively cooperate with doctors for examination and treatment, prevent for different reasons, and at the same time, it is best to use a variety of combined treatment after surgery, and the most commonly used Chinese herbs to identify and adjust the treatment, which can effectively regulate the patient’s physique and can reduce the chance of recurrence.
