Imagine a tiny army of radiation beams marching towards a brain tumor, each beam precisely targeted to blast the cancerous cells without harming the surrounding healthy tissue. That’s the power of Stereotactic Radiosurgery (SRS), a highly accurate radiation therapy for small, well-defined tumors.
Unlike traditional radiation therapy, which delivers a wide beam of radiation, SRS uses multiple narrow, focused beams that meet at the tumor like arrows piercing a bullseye. This pinpoint accuracy allows doctors to deliver high doses of radiation directly to the tumor while sparing nearby critical structures, such as the eye or brain stem.
The key to SRS’s precision lies in its sophisticated technology. Advanced imaging techniques, including CT and MRI scans, are used to create a three-dimensional map of the tumor and surrounding anatomy. This map is then fed into a specialized treatment planning system that calculates the exact dose and direction of each radiation beam.
The actual treatment is delivered using a state-of-the-art radiation therapy machine that rotates around the patient, bombarding the tumor from multiple angles. The whole process is quick and painless, with most treatments taking less than an hour.
SRS is particularly effective for treating small, well-circumscribed tumors that are located in hard-to-reach areas, such as the brain or spine. It has been shown to be successful in treating a wide range of tumors, including acoustic neuromas, meningiomas, pituitary tumors, and metastases.
If you’re facing a small brain tumor, SRS might be the precision weapon you need to vanquish it without harming the surrounding tissue. Talk to your radiation oncologist to learn more about this cutting-edge treatment option.
