This radiotherapy uses several accurately focused radiation beams to treat cancers and problems in the brain, neck, lungs, liver, spine and other regions of the body. Stereotactic radiosurgery is not surgery, as there’s no incision but instead uses 3D imaging to target high doses of radiation to the affected region with very less impact on the surrounding healthy tissue. It works by destroying the DNA of the targeted cells, reducing the ability to reproduce, and thereby making the tumours shrink. Stereotactic radiosurgery of the brain and spine is typically completed in one session.
Who Needs Stereotactic Radiosurgery?
Stereotactic radiosurgery has been widely recommended by your doctor to treat a variety of neurological and other conditions, including:
How Is Stereotactic Radiosurgery Performed?
Stereotactic radiosurgery is specially designed equipment that focuses on several small beams of radiation on a tumour or target. Each beam has less impact on the tissue it travels through, but a targeted dose of radiation is provided to the site where all the beams meet. The high energy dose of radiation transmitted to the affected region makes the tumours shrink and blood vessels close off over time following treatment and robbing the tumour of its blood supply. In most cases, this radiosurgery has a lower risk of side effects.
Stereotactic radiosurgery usually causes milder side effects than conventional radiotherapies. Some of the side effects are temporary and settle in a few weeks including: Fatigue skin irritation at the treatment site Hair loss at the treatment site Headache Seizure Numbness Weakness Nausea Vomiting Diarrhoea
With this radiosurgery, the tumour may shrink over a period of 18 months to two years. However, the key goal of the treatment for benign tumours is to avert any future tumour growth.
Stereotactic radiosurgery uses a high dose of radiation to kill the tumour cells but does not damage the surrounding healthy tissue. You should have between 1 to 8 sessions depending upon the type and location of the tumour.
