What is Radiosurgery?
Radiosurgery is a non-invasive treatment technique used primarily to ablate tumors. Radiosurgery is most suitable for small, well-defined tumors that can be seen in imaging, such as a CT or an MRI scan. Despite the use of the word "surgery" in its name, radiosurgery does not involve removing the tumor with a surgical knife. Instead, a focused high-intensity beam of radiation is used to target a tumor while minimizing dosage to healthy tissue.
Put simply, radiosurgery is a highly precise, intensified form of radiotherapy, or radiation therapy. Physicians may utilize radiosurgery techniques when conventional radiotherapy is not an appropriate option for a patient’s particular case. It can be used as the first line of treatment for some tumors, or for tumors that are otherwise inaccessible for open surgery. Radiosurgery can be used in conjunction with chemotherapy, radiotherapy, or as a palliative treatment when curing the cancer is not possible.
In addition to treating cancer, radiosurgery has also been shown to be beneficial for the treatment of some non-cancerous, neurovascular conditions. We recommend that you talk to your radiation oncologist about which treatment method is right for you.
