Stereotactic Radiosurgery (SRS) is a non-invasive medical procedure that uses radiation therapy used to treat brain tumors that are both cancerous and non- cancerous. Despite its name, SRS does not involve traditional surgery with incisions. Instead, it utilizes highly focused radiation beams to target and treat specific areas of tissue.
Here are some key points about Stereotactic Radiosurgery:
- Precise Targeting: SRS relies on advanced imaging techniques (such as MRI or CT scans) to precisely locate the target area within the body. This ensures that the radiation is directed with high accuracy.
- Concentrated Radiation Beams: Multiple beams of radiation are focused on the target from various angles. Where these beams intersect, a high dose of radiation is delivered to the specific area while minimizing exposure to surrounding healthy tissue.
- Single or Fractionated Treatments: SRS can be administered in a single session (which is typical for smaller lesions) or over several sessions (known as fractionated SRS), which may be more appropriate for larger or more complex cases.
- Wide Range of Applications: SRS is commonly used to treat various types of brain conditions, including malignant (brain metastases, recurrent glioblastoma or any other malignant brain tumor) and benign tumors (Acoustic Schwanomma, Meningiomas, Fibrous Tumors etc, Also, Arteriovenous Malformations (AVMs), trigeminal neuralgia, and some functional disorders.
- Minimal Discomfort and Recovery: Since SRS does not involve surgical incisions, there is typically less discomfort, and patients can usually return to their normal activities relatively quickly after the procedure.
- Multi-Disciplinary Approach: SRS is often a collaborative effort involving neurosurgeons, radiation oncologists, medical physicists, and other specialists. They work together to plan and execute the treatment.
- Monitoring and Follow-Up: Patients who undergo SRS are usually monitored through regular follow-up appointments and imaging studies to assess the effectiveness of the treatment and ensure there are no adverse effects.
- Considerations and Risks: While SRS is generally considered safe, there can be risks associated with the treatment, including potential damage to nearby healthy tissue. These risks are carefully evaluated and weighed against the potential benefits before deciding on the treatment.
It’s important to note that the suitability of Stereotactic Radiosurgery as a treatment option depends on the specific condition, size, and location of the target area. The decision to pursue SRS is typically made by a team of medical professionals based on a thorough evaluation of the patient’s individual case.
