What is SRS?

SRS therapy uses finely targeted radiation beams to treat tumours, vascular malformations, or functional disorders without making any incisions. The precision is so high that surrounding tissues receive minimal exposure, helping preserve brain and nerve function.

In simple terms, SRS works like a “radiation scalpel,” treating the affected area with accuracy while avoiding the need for open surgery.

Why is the SRS Procedure Needed?

An SRS procedure is often recommended when tumours or lesions are located deep within the brain or in areas where conventional surgery may carry higher risks. SRS provides a non-invasive alternative that can achieve effective control or reduction of abnormal tissue.

Common Reasons and Key Conditions Treated

• Benign brain tumours such as meningiomas or acoustic neuromas.
• Metastatic brain tumours from cancers in other parts of the body.
• Arteriovenous malformations (AVMs).
• Trigeminal neuralgia and other functional disorders may also be present.
• Recurrent tumours previously treated with surgery or radiation.

Types of SRS / Procedure Variations

There are different systems used for delivering SRS treatment, and the choice depends on the location, size, and nature of the tumour.

• Gamma Knife SRS: Often used for small brain tumours and functional disorders.
• Linear accelerator (LINAC)-based SRS: A versatile option used for brain and body lesions.
• CyberKnife SRS: Robotic system offering flexible beam angles.
• Fractionated SRS: Delivered over multiple sessions for sensitive locations.

Indications for SRS

SRS may be recommended when:

• The tumour is small and well-defined.
• Surgery is considered too risky due to the tumour’s location.
• There is tumour recurrence after previous treatment.
• Functional disorders require targeted nerve treatment.
• The patient prefers a minimally invasive treatment option.

Who Should Avoid or Delay SRS?

SRS may not be suitable for all patients. Some may require alternative treatment approaches or temporary stabilisation before undergoing therapy.

• Large tumours exceeding size limits for stereotactic radiation.
• Diffuse or irregularly shaped lesions.
• Uncontrolled swelling or raised intracranial pressure.
• Medical instability requiring immediate attention.
• Pregnancy, depending on treatment location and risk assessment.

Preparing for SRS

• MRI, CT, or PET scans to map the exact location of the lesion.
• Review of medical history, symptoms, and previous treatments.
• Fitting of a head frame or mask to keep the head still during treatment.
• Discussion of the treatment plan, expected sensations, and after-care.
• International patient guidance for travel, reports, and scheduling.

What Happens During the SRS Procedure?

SRS is typically completed in a single session, although some cases may need several sessions. The procedure is non-invasive, and patients remain awake, with the team ensuring comfort throughout.

Step-by-Step Breakdown

• Initial positioning using a frame or custom mask.
• Imaging scans to confirm precise tumour location.
• Computer-assisted treatment planning by specialists.
• Patient placed on the treatment table with minimal movement.
• Radiation beams delivered from multiple angles with pinpoint accuracy.
• Completion of treatment with no recovery room stay required.

Recovery After SRS

Most patients return home the same day. Temporary fatigue, mild headache, or swelling at the treatment site may occur, but these usually settle within days. Normal activities can often be resumed quickly, though rest is encouraged for the first 24 hours.

Follow-up scans are part of the recovery process to monitor tumour response and ensure stable, long-term results.

Risks & Complications

Possible complications may include temporary headache, swelling, mild nausea, or localised irritation. Rarely, delayed radiation effects may occur, particularly when treating sensitive brain areas. Careful planning and monitoring help reduce these risks significantly.

Benefits of SRS

• Non-invasive treatment with no surgical incision.
• High precision with reduced impact on healthy tissue.
• Often completed in a single session.
• Useful for areas considered too risky for open surgery.
• Short recovery time and rapid return to daily life.
