Not a diagnosis and not final medical advice. Must be reviewed by a doctor.

What is it?

SRS delivers high doses of radiation to small targets in the brain with millimeter accuracy, so that surrounding brain tissue is better protected.

This approach is often discussed in limited brain lesions, including spread of lung, breast, or melanoma cancer.

Planning to use a head frame or other immobilization system as a position reference.

High resolution imaging and an immobilization system are used to map the target, then several radiation beams are directed to meet the target.
How SRS (intracranial stereotactic radiotherapy)

How it works

High resolution imaging and an immobilization system are used to map the target, then several radiation beams are directed to meet the target.

Position in the treatment pathway: Discussed in limited brain lesions, both as the main therapy for these lesions and as an adjunct after other therapies. If the lesions are numerous and scattered, other options such as whole brain radiotherapy may be considered.

Which cancers is it usually discussed for?

Usually considered

  • Lesions are limited in size, generally less than three centimeters in diameter.
  • The number of lesions that can still be treated in one or more sessions.
  • Common conditions that allow undergoing sessions in a fixed position.

Usually not a candidate

  • Lesions that are very large or widespread throughout the brain.
  • Targets attached to vital structures with no margin of safety.

What is the process like?

  1. Preparation 1

    Planning imaging includes brain MRI.

  2. Preparation 2

    Installation of immobilization device.

  3. Preparation 3

    Medication adjustments if any.

  4. Monitoring

    Monitoring neurological symptoms.

All preparation

  • Planning imaging includes brain MRI.
  • Installation of immobilization device.
  • Medication adjustments if any.

All monitoring

  • Monitoring neurological symptoms.
  • Periodic MRI to assess response and local control.
  • Monitoring the side effects of radiation on surrounding tissue.

Risks and points to watch

Side-effect notes, not a complete list

This list covers categories commonly discussed. Individual risk is always assessed by the treating team.
  • Fatigue, headache and local complaints may appear temporarily.
  • In some cases, temporary swelling can occur in the therapy area that needs to be treated with medication.
  • Long-term effects depend on location and dose.

Cost and access

Cost figures depend heavily on location, facility and payer. We do not show estimated figures on this page; what can be prepared first are the questions.

Access status not yet verified

Studies are filtered from the public registry. Site readiness and international patient acceptance still need confirmation before any travel is planned.

Questions for the doctor

  • How many lesions will be treated and why were these targets chosen?
  • What is the risk to brain tissue around the target?
  • What is the plan if new lesions appear in the future?
