Susan suffered from headaches for 1-2 days caused by a tumor close to the carotid artery. She was treated with the CyberKnife and now only 10% of the original tumor remains but acrimedley caused growth hormone which puts her at risk for other diseases. There was no guarantee that surgery could remove the last 10% of the tumor but she decided to go with the CyberKnife for treatment after seeing the CyberKnife film and now her growth hormone is at 150, which is well within the normal range.
