Stereotactic Radiosurgery is a highly precise form of radiation therapy which can be used to treat:

  • Brain tumours
  • Extra cranial lesions (Stereotactic Body Radiotherapy – SBRT)
  • Post-operative treatment to eliminate any residual tumour tissue
  • Abnormal blood vessels (known as AVM)

Despite its name, Stereotactic Radiosurgery does NOT involve any surgery. It is a procedure which allows precisely focused high-dose X-ray beams to be delivered to a small, localised area targeting the tumour.

Goal of Stereotactic Radiosurgery

The goal of radio surgery is to destroy tumour cells without harming surrounding healthy normal tissue.

Advantages of using Stereotactic Radiosurgery

It works the same way as other forms of radiation treatment. It does not remove the tumour but it will damage the DNA inside cells making them unable to divide or reproduce. Abnormal cancer cells are more sensitive to radiation because they divide more quickly than normal cells. After the treatment, benign tumours usually shrink over a period of 18-24 months. In malignant tumours, the shrinkage many occur more rapidly.

Types of Cancers which can be treated with Stereotactic Radiosurgery:

  • Meningioma
  • Astrocytoma
  • Glioblastoma
  • Brain lymphoma
  • Nasopharyngeal carcinoma
  • Liver metastasis
  • Prostate cancer
  • Small cell lung carcinoma
  • Acoustic neuroma
  • Arteriovenous malformation (AVM)

Side effects of Stereotactic Radiosurgery

Like radiation therapy, the general side effects include fatigue, loss of appetite and headache. The side effects vary from person to person depending on the location of the treatment. Some people experience no side effects at all.
