Stereotactic body radiation therapy (SBRT) is a non-surgical radiation therapy that delivers a high dose of radiation to destroy the tumour while reducing the possibility of damaging the healthy tissues. It is a procedure as similar to treating Central Nervous System (CNS), except that it treats the tumours outside CNS. Depending on the size and location of the tumour, the patient is usually given a treatment in a single dose or more than 5 doses. It is usually meant for treating small tumours (3-7cms) of pelvic, kidney, spine liver as well as prostate cancer, pancreatic cancer and sarcomas throughout the body. The equipment has the capability to adjust itself according to the tumour's physical and biological parameters in order to deliver the right dosage, which is precisely targeted to kill the cancerous cells.
