A brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor. [ 1 ][ 2 ] The metastasis typically shares a cancer cell type with the original site of the cancer. [ 3 ] Metastasis is the most common cause of brain cancer, as primary tumors that ...
Stereotactic radiosurgery provides an efficient, safe, and minimal invasive treatment alternative [15] for patients diagnosed with malignant, benign and functional indications in the brain and spine, including but not limited to both primary and secondary tumors. [16] Stereotactic radiosurgery is a well-described management option for most ...
Radiation oncologists perform stereotactic treatments, often with the help of a neurosurgeon for tumors in the brain or spine. There are two types of stereotactic radiation. Stereotactic radiosurgery (SRS) is when doctors use a single or several stereotactic radiation treatments of the brain or spine.
People who receive stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) for the treatment of metastatic brain tumors have more than twice the risk of developing learning and memory problems than those treated with SRS alone.
1423298. [ edit on Wikidata] Radiosurgery is surgery using radiation, [ 1 ] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer. Radiosurgery was originally defined by the ...

Glioblastoma. Glioblastoma, previously known as glioblastoma multiforme (GBM), is the most aggressive and most common type of cancer that originates in the brain, and has a very poor prognosis for survival. [ 6 ][ 7 ][ 8 ] Initial signs and symptoms of glioblastoma are nonspecific. [ 1 ] They may include headaches, personality changes, nausea ...
During treatment, the image guidance system captures 3D images, tracks the movement of tumors, and guides the robotic arm to accurately aim the treatment beam at the moving tumor. [2] The system is designed for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT).
