Radiosurgery is the practice of using precisely aimed radiation beams to destroy tumors and lesions in the body.
Radiosurgery does not remove the tumor or lesion. Instead, it damages the DNA of the tumor cells. The cells then lose their ability to reproduce and eventually die.
In lesions such as arteriovenous malformations (AVM), a tangle of blood vessels in the brain, radiosurgery can cause the blood vessels to thicken and close off.
At Barrow, radiosurgery is primarily used to treat the following:
- Brain tumors
- Tumors of the head and spine
- Arteriovenous malformations (AVM)
- Trigeminal neuralgia
- Acoustic neuroma
You may be a good candidate for radiosurgery if you have a brain or spinal tumor that is known to respond well to radiation therapy.
For some cancerous tumors, radiosurgery may be used after conventional open surgery to destroy any cancer cells that were left behind.
If you have an arteriovenous malformation (AVM), you may be a candidate for radiosurgery. However, results from radiosurgery for AVMs can take time. The AVM may be at risk for bleeding during this time.
