The most common method for the treatment of the brain tumours is surgery. Surgery is regarded as a must for removing the cells that grow spontaneously or the ones that reach the brain after passing by other organs. The brain surgery aims at removing the cancerous or benign tumours completely from the tissues.

In addition to classical surgeries, for the treatment of brain tumours, World Health Network uses treatment techniques like Gamma Knife and Cyber Knife, which operate on rays, when open surgery is not possible and the patient is under high risk. As scalpel is not used on the patient, tumour can be operated on in a quicker and less risky way than the classical surgeries. The operation is completed in an hour without using any anaesthesia or sutures. After the application of Gamma Knife, patients can get back to their jobs and social lives the day after. The fact that this treatment does not limit one's functions places it among the most preferred options.
