Usually benign brain tumors seldom recur after removal, and very few benign brain tumors are more likely to recur, such as craniopharyngioma.
Generally, benign brain tumors have clear boundaries with the surrounding tissues and can be completely removed by surgery, and usually no tumor tissue will be left. However, some tumors cannot be completely removed due to their deep location or unclear boundaries with surrounding tissues, and there is a possibility of recurrence after surgery, which can be prevented by postoperative radiotherapy.
A few benign brain tumors, such as craniopharyngioma, may recur even after surgical resection.
For tumors that are not completely removed from the brain, they can be treated by gamma knife, which is a relatively advanced extracorporeal radiation therapy that can effectively treat benign tumors. It has the advantages of small trauma, fast recovery and precise positioning.
It is recommended that patients suffering from benign brain tumors follow the doctor’s instructions for follow-up treatment after surgery and undergo regular review to minimize the possibility of recurrence.
