The first option is always surgery because the aim of brain tumor treatment is complete destruction of the tumor. Of course, it is more important for the neurosurgeon to compare the damage given to the patient during surgery and the benefit of surgery; that is, the decrease in the number of tumor cells, and the reduction of the pressure on the brain around the tumor. In cases when it is decided not to apply surgery or if it is not possible to remove the entire tumor by surgery; chemotherapy, treatment with various cancer medicines and/or other radiotherapy, that is, treatment with high-energy radioactive particles are on the agenda.
It may also be necessary to make a number of adjustments at the order and frequency of application of all these treatments. Though it is often not possible to treat the brain tumor definitely by means of such treatments, at least the quality of life of the patient is maintained and the survival time is prolonged.
