Stereotactic
Radiosurgery (SRS)
Stereotactic Radiosurgery (SRS)
Stereotactic Radiosurgery (SRS) is an advanced, non-invasive form of radiation therapy used primarily to treat small brain tumors and neurological conditions. Despite the name, SRS doesn’t involve any actual surgery or incisions. Instead, it delivers high-dose, precisely focused radiation beams directly to the affected area, preserving nearby healthy brain tissue.
At Thangam Hospital, our Radiation Oncology and Neurosciences teams work together to offer cutting-edge SRS treatments using advanced imaging and high-precision equipment. We are among the few centers in the region providing this sophisticated therapy for both cancerous and non-cancerous brain conditions.
What is Stereotactic Radiosurgery?
SRS is a highly targeted radiation therapy technique that uses converging beams of radiation to destroy abnormal cells or tumors with extreme precision. It is typically performed in a single session, though some cases may require a few sessions (fractionated SRS).
SRS is ideal for:
- Patients with small or hard-to-reach brain tumors
- Individuals who cannot undergo traditional surgery due to health risks or tumor location
- Cases requiring additional treatment after surgery to destroy remaining cancer cells
Conditions Treated with SRS at Thangam Hospital
Stereotactic Radiosurgery is used to treat a wide range of brain tumors and neurological disorders, including:
- Benign brain tumors: Meningioma, Pituitary Adenoma, Acoustic Neuroma, Craniopharyngioma
- Malignant brain tumors: Glioblastoma, Glioma, Metastatic Brain Tumors, Pineoblastoma
- Vascular abnormalities: Arteriovenous Malformations (AVMs)
- Functional conditions: Trigeminal Neuralgia, Paraganglioma
- Other tumors: Chordoma, Hemangioblastoma
SRS may also be used to treat select tumors outside the brain, such as in the lungs, liver, and pancreas. In those cases, the technique is called Stereotactic Body Radiation Therapy (SBRT).
The SRS Procedure at Thangam Hospital
1. Pre-Treatment Planning
Our specialists will:
- Conduct a thorough medical evaluation and imaging workup (MRI, CT, or angiogram)
- Discuss your diagnosis, treatment goals, and expected outcomes
- Explain the procedure, side effects, and recovery
- Instruct you on pre-procedure steps, such as fasting or pausing certain medications
You may also be fitted with a custom head mask or frame to ensure accurate and consistent positioning during treatment.
2. Treatment Day
During the session:
- You will lie comfortably on a treatment table with your head immobilized
- A Linear Accelerator (LINAC) or other SRS unit will deliver multiple beams of high-dose radiation from different angles
- Imaging guidance ensures the tumor is precisely targeted while sparing surrounding healthy tissue
- The entire procedure is non-invasive and painless
- You can communicate with the treatment team via intercom throughout the session
3. Duration
Most SRS treatments are completed in 1 to 2 hours
Some patients may need multiple smaller-dose sessions over 3–5 days (fractionated radiosurgery)
What to Expect After SRS
Most patients can go home the same day after a short observation period. You may resume daily activities within a day or two, depending on how you feel.
Common Side Effects (temporary and manageable):
- Fatigue
- Headache
- Mild nausea or vomiting
- Skin redness at the treatment site
- Temporary hair loss near the radiation area
Our team will provide medications or supportive care as needed.
Benefits of Stereotactic Radiosurgery at Thangam Hospital
- No incisions, no general anesthesia
- Precision targeting to protect healthy tissue
- Outpatient procedure with quick recovery
- Effective tumor control in a single or few sessions
- Minimal side effects compared to conventional brain radiation
SRS is particularly valuable for treating deep-seated, inoperable, or previously irradiated tumors.
Follow-Up and Recovery
- You’ll return for follow-up appointments to:
- Monitor side effects and recovery
- Conduct imaging scans to assess tumor response (typically within 1–3 months)
- Evaluate neurological function and overall health
Tumors may shrink over time, and symptoms often improve within weeks to months, depending on the condition being treated.
