FREQUENTLY ASKED QUESTIONS

  • Can a brain tumor called inoperable actually be removed?

    Sometimes. The term may reflect the tumor’s location or the risks of a particular approach. Specialized review may reveal additional options in selected cases, but some tumors cannot be safely removed.

  • Should I get a second opinion before brain tumor surgery?

    It can be especially useful when the tumor is complex, treatment recommendations differ, or the proposed operation carries substantial risk. It may also confirm that the existing plan is appropriate.

  • Can large pituitary tumors be removed through the nose?

    Many can be treated endoscopically through the nose, but suitability depends on extension into surrounding structures, vascular anatomy, and other features—not size alone.

  • Is minimally invasive brain surgery always better?

    No. A smaller incision is not necessarily safer. The priority is adequate access and preservation of neurological function.

  • What if my tumor returned after previous surgery?

    Management depends on tumor type, growth, prior treatments, and anatomy. Options can include repeat surgery, radiation, medication, or observation.

  • Do I need to have surgery to request a consultation?

    No. A consultation can assess whether surgery is indicated or whether nonsurgical treatment or observation is more appropriate.

  • What should I bring to a second-opinion appointment?

    Bring the actual MRI or CT images, radiology reports, prior operative and pathology reports, treatment history, and current medications if available.
