What should you know about laser gamma knife?

Gamma Knife is a form of stereotactic radiosurgery that directs many radiation beams at a carefully planned target in the brain. It does not use a surgical knife. Laser interstitial thermal therapy is a different procedure that uses a probe and heat, usually guided by imaging, to treat selected brain lesions.

Focused radiation may be considered for some brain tumours or brain metastases, depending on their number, size, location, symptoms, and previous treatment. Whole Brain Radiotherapy and Brain Tumour Surgery are different options, and suitability must be judged from brain imaging and the overall diagnosis.

Ask the centre to write down the exact procedure name, device, target, and purpose. Your preparation may include a planning MRI or CT, medication review, and instructions about eating, medicines, and support home afterward. Ask how treatment may affect thinking, balance, seizures, headaches, or the part of the brain being treated.

Discuss whether the intended approach is Gamma Knife, CyberKnife, stereotactic radiosurgery, or a laser procedure. The differences affect anaesthesia, treatment sessions, monitoring, and recovery.

Seek emergency help for a seizure lasting longer than usual, sudden weakness or numbness, new confusion, severe worsening headache, repeated vomiting, fainting, or difficulty speaking or walking. After treatment, follow the centre's urgent-contact instructions for fever, worsening drowsiness, or a new neurological change.

Ask which technology is being proposed and why, what the target is, how many sessions are planned, and whether a frame or anaesthesia is needed. Discuss alternatives, expected short-term effects, warning symptoms, and how follow-up scans will assess the treated area.
