Radiosurgery can be a safe and viable alternative to conventional surgery… learn more in the following section.

When it comes to brain lesions, one of the most common questions we receive at Radioterapia Siglo XXI is: Is radiosurgery an alternative to conventional treatment, or is it only used in very specific cases?

La respuesta depende de muchos factores como el tipo de lesión, su ubicación, tamaño y estado general del paciente. En este artículo te explicamos The answer depends on many factors such as the type of lesion, its location, size, and the patient’s overall condition. In this article, we explain when radiosurgery is a viable option, its advantages, what types of lesions can be treated with this advanced technique, and when traditional surgery might be more appropriate.

What is Radiosurgery and How Does It Differ from Radiotherapy?

Although their names may sound similar, radiosurgery and radiotherapy are not the same. la radiocirugía y la radioterapia no son lo mismo.

• Conventional Radiothperay: Delivered over multiple sessions (daily over several weeks) and used to treat different types of cancer, including some brain tumors. It works by administering low doses of radiation per session, allowing healthy tissue to recover between treatments.
• Radiosurgery (SRS – Stereotactic Cranial Radiosurgery): A highly precise, high-dose treatment usually delivered in a single session or a few (up to five). It does not involve scalpels or incisions—its name refers to the surgical-level precision of radiation delivery. Check more about this proccdure.

In summary:

• Radiotherapy = gradual, fractionated treatment.
• Radiosurgery (SRS)) = pinpoint, high-precision treatment.

And What About Conventional Brain Surgery? When Is It Necessary?

Conventional neurosurgery remains a fundamental tool, especially when:

• A biopsy is needed to confirm a diagnosis.
• The lesion is causing significant compression of brain tissue or increased intracranial pressure.
• Complete or partial tumor removal is required to quickly relieve symptoms.
• Large lesions or masses do not respond to non-invasive treatments.

In such cases, open surgery allows direct visual and manual intervention on the affected tissue. It may later be combined with radiosurgery or radiotherapy to complete treatment and reduce the risk of recurrence.

When Is Radiosurgery Recommended for Brain Lesions?

La Radiosurgery is an excellent option when: cuando:

• Preserving healthy brain tissue is essential.
• Lesions are small or moderately sized.
• They are located in areas difficult to access by conventional surgery.
• The patient cannot undergo invasive surgery.

What Types of Brain Lesions Can Be Treated with Radiosurgery?

Radiosurgery is effective for both malignant (cancerous) and benign (non-cancerous) lesions. (Check real cases here)

Malignant lesions treated with radiosurgery:

• Brain metastases (cancer spread to the brain from another body site).
• Low- or intermediate-grade gliomas (in selected cases).
• Recurrent astrocytomas.

Benign lesions treated with radiosurgery:

• Meningiomas.
• Acoustic neuromas (vestibular schwannomas).
• Arteriovenous malformations (AVMs).
• Pituitary adenomas.
• Trigeminal neuralgia (a painful neurological condition).

What Are the Advantages of Radiosurgery Compared to Other Options?

• High precision: Advanced imaging and AI-based systems direct radiation exactly where it’s needed.
• Minimal impact on healthy tissue: The radiation dose is concentrated on the lesion, sparing surrounding brain structures.
• Non-invasive: No scalpels, no hospital stay, no general anesthesia.
• Fast recovery: Many patients resume normal activities the same day.
• High effectiveness: Especially for single, well-defined lesions.

When Is Radiosurgery Not Recommended?

• When the lesion is too large.
• If there are multiple, scattered lesions requiring a broader approach.
• When the diagnosis is unclear (a surgical biopsy is needed).
• In cases of significant edema (swelling) or compression of vital structures.

How Do I Know If I Am a Candidate for Radiosurgery?

At Radioterapia Siglo XXI, we conduct a personalized evaluation with a multidisciplinary team of specialists in neuro-oncology, radiotherapy, and medical physics. The assessment includes:

• Imaging studies (MRI, CT scan, PET).
• Review of medical history.
• Evaluation of lesion type and the patient’s clinical condition.

Conclusion: Radiosurgery, Radiotherapy, or Conventional Surgery?

Each case is unique, and the best treatment depends on multiple factors. Radiosurgery is a safe, precise, and effective option for many brain lesions, but it does not replace surgery or conventional radiotherapy in every situation. The ideal approach is to have a specialized team design a personalized, evidence-based treatment plan.
