A team in Zürich, Switzerland, has successfully destroyed a major portion of an infiltrating brain tumor located deep within the brain without any incisions. Ultra sound technology was used to eradicate the cancerous cells. Ultrasonic energy is guided by magnetic resonance or ultra sound imaging to treat tissue without the use or radiation or surgery. Javier Finding, a neurosurgeon in Switzerland, stated that " the patient was awake and responsive during the treatment and we were able to successfully target and destroy a part of the tumor located deep within the patient's brain. We are very encouraged that we could utilize focused ultrasound to accomplish this with no side effects or complications."
