There is no very clear statistical indicator of the growth rate of pituitary tumors, because each person’s physique is different, and the growth rate of pituitary tumors is different for each person, with different benign and malignant properties, different blood supply, and different surrounding nerve tissues. Generally if pituitary tumor is suspected, or if it is relatively small, it is basically reviewed once every three months and needs to be looked at specifically depending on the specific condition. Some pituitary tumors may grow 1cm, some may grow 5mm, and some may not change, so everyone is different, and sometimes after aggressive treatment, it does make the growth rate very, or even not grow. Therefore, there are no specific statistical indicators or data to determine the growth rate in this regard, but only through regular review to see the degree of change of the corresponding indicators.
