Steps to take before the procedure
An imaging study of the area will be done carefully to plan the destruction of only tumour cells and not the healthy cells. Many scans will be done to diagnose and identify the mass of tumour cells. 3D imaging techniques will be used to mark the exact portion in the brain.
What happens during the treatment?
An individualised treatment mask will be provided to the patient, which is custom made for the patient, to hold the head in correct position. The patient will lie on a treatment table or therapy couch. The mask will be attached to the table or couch. High energy radiation beams will be directed on the marked spots through a machine called linear accelerator. The session takes a few minutes.
After the procedure
The treatment is done on an outpatient basis. But, a patient undergoing chemotherapy will require hospital admission. The doctor may prescribe a few medicines such as steroids or blood thinners on a preventive basis to minimise the after-effects of the treatment.
