Frequently Asked Questions

  • Malignant Tumors: metastatic tumors (cancer spread to the brain), Glioma, chondrosarcoma
  • Benign Tumors: acoustic neuromas (vestibular schwannoma), Meningiomas, pituitary adenomas, low grade Glioma and skull base tumors
  • Vascular Abnormalities: Arteriovenous malformations (AVMs), cavernous angiomas (cavernous malformations)
  • Functional Disorders: trigeminal neuralgia

Gamma Knife technology allows your physician team to treat brain tumors of any size (up to 6 centimeters) or shape, and in any location, with accuracy to 5 millimeters. Tumors that are close to critical brain structures can be safely targeted.

What are the side effects of Gamma Knife?
Patients go home the same day as their Gamma Knife treatment. The most commonly reported side effects are mild and short-lived. They usually clear up within a few days of the procedure and can include fatigue

  1. Frame attachment (10 min)
  2. Imaging – MR (20 min)
  3. Treatment planning (20 min)
  4. Single treatment session (60 min)

 

All Gamma Knife procedures are day cases compared to traditional surgery which may require 5 to 7days stay in the hospital

Yes you may. Patient needs to come for follow up every three (3) months with magnetic resonance imaging (MRI). This is to see if the tumors stop growing or shrink.

The success rate for Gamma Knife is 90% killing or shrinking the brain tumors and stopping their growth.

Since 2019, UKMSC GKC has treated more than 400 cases.

Treatment is different on a case-to-case basis. Please call +60127037855 for more information about Gamma Knife and to book an appointment.
