When you’re getting ready to undergo a Gamma Knife procedure, knowing exactly what to expect will better prepare you for the day of treatment. Gamma Knife radiosurgery, unlike traditional surgery, doesn’t come with strict rules such as abstaining from eating and drinking 12 hours before surgery, nor does it require that you get ready for a lengthy hospital stay. Nonetheless, being prepared with knowledge of the procedure and the different steps, both before and after, can make the process much smoother for you.
