The recurrence of pituitary tumors in the brain several years after surgery must be treated on a case-by-case basis, as each person is different. Because each individual is different and has a different type of disease and a different specific pathology type of pituitary tumor, there is no specific time only a stage. If the pituitary tumor is malignant possibly, it will basically recur in a period of 3-6 months. But if the pituitary tumor is benign, it is possible that it may not recur for 5-6 years, and these are possible cases. And sometimes for extremely malignant cases, recurrence can occur just after having this surgery and being discharged for a review. Therefore, it is recommended that patients should be reviewed regularly so that they can be detected and treated early from the very root.
