The effects of the Gamma Knife treatment will not be immediate but will be seen over a period of time. Radiation treatments are designed to stop the growth of tumours or lesions, which means the progress will only be seen over a period of weeks or months. Your doctor will stay in contact with you during this period; you may have to undergo follow-up MRI, CT or angiography examinations to monitor your progress.
Generally most patients experience no immediate side-effects from the treatment, though some may experience some mild side-effects such as nausea/vomiting, headache and scalp numbness.
