How long can one live after brain tumor surgery?

The survival time after brain tumor surgery depends on multiple factors, including the tumor's pathological nature, location, extent of resection, and the follow-up treatments administered after surgery. 1. Benign tumors: If a benign tumor can be completely removed, patients usually can survive for a long time and may even achieve full recovery. Even if complete resection is not possible, residual tumors can often be controlled through methods such as radiotherapy, and the patient's survival period can still be relatively long, potentially reaching 10 years or even more than 20 years. 2. Malignant tumors: The survival time for malignant tumors is generally shorter. The survival period varies depending on the tumor's grade and level of malignancy. For example, high-grade gliomas (such as grade IV gliomas) typically have a shorter survival time, often around 1.5 years. With advancements in surgical techniques and treatment methods, such as the use of tumor-treating fields, the patient's survival time may be prolonged, with some individuals surviving for 2 years or even longer.
