Can recurrence of brain cancer be cured by surgery?

Brain cancer is a type of disease in tumor surgery. The most feared thing about brain tumors is recurrence after surgery. Once it reaches this stage, Western medicine has no better treatment. What should we do? Can brain cancer be cured by surgery after recurrence? Please see the detailed answers given by experts below.

Many people believe that the recurrence of brain tumors is due to the reappearance of clinical symptoms and signs that had disappeared or alleviated after brain tumor surgery, and the regrowth of meningioma at the original surgical site found during imaging examinations or reoperations.
Obviously, when surgical resection is incomplete, the tumor will continue to grow and this is not a true recurrence. In such cases, the return of clinical symptoms is attributed to the continued increase in the size of the tumor. Surgeons often consider the tumor to be completely removed even though microfoci have been missed. When a macroscopic tumor mass is found in the venous sinus or at a site distant from the primary tumor, it may be easier to judge it as continued growth or recurrence, but it is difficult to assess the exact amount of tumor remaining in the original site. In addition, it is also difficult to evaluate whether it is simply invasion of the tumor into the venous plug or bone tissue.
