Stereotactic Radiosurgery (SRS) for Brain Cancer
Stereotactic Radiosurgery (SRS), also called Stereotactic Radiation Therapy (SRT), is an advanced brain cancer treatment option at CTCA. A nonsurgical form of brain cancer radiation therapy, stereotactic radiosurgery delivers high doses of radiation to tumors with great precision.
Using imaging technology, our radiation oncologists first map the location of the brain tumor. Then, using highly sophisticated computer equipment, SRS shapes multiple radiation beams tightly around the brain tumor to destroy cancerous cells.
With SRS technology, we can focus radiation to the outline of the tumor and protect nearby healthy tissue, which is especially important for areas in the brain.
SRS is generally used to treat small tumors contained in localized areas of the brain or spinal cord, as well as blood vessel abnormalities in the brain. There are some circumstances where we may use SRS to treat metastatic brain tumors (as an alternative to whole-brain radiation or surgical resection), particularly for tumors in more than one location.
Advantages of SRS for Brain Cancer
- SRS precisely focuses radiation around the brain tumor from different angles, allowing us to deliver a large radiation dose to the tumor with less damage to nearby healthy brain tissue.
- SRS modulates the intensity of the radiation beams, sparing the surrounding brain tissue from significant doses of radiation.
- Using this form of brain cancer radiation therapy, we can reach tumors in the brain without the risks of surgery. There is no incision, minimal discomfort, and reduced recovery times.
- Because of its precision, SRS may be an option for individuals who have received previous radiation, as SRS can avoid previously treated areas.
Helping You Maintain Your Quality of Life
Your CTCA care team anticipates and proactively manages the side effects of brain cancer radiation therapy. Before, during and after your SRS treatment, you’ll receive supportive therapies designed to keep you strong, reduce the side effects of radiation, and promote your overall well-being.
