Hi there: so sorry you are going through this. Cancer is a hateful disease that I wish they could find a cure for. You don't give us any info on your Dad, age, stage of disease, treatment plan etc. Yes there are miracles & there are survivors and one should always keep hoping (definition of HOPE - Hanging On Praying Expectantly) If the radiologist thinks he's a candidate for cyberknife perhaps you could ask him to do the referral so that your Dad could get in sooner. Just a suggestion, as I have no experience with cyberknife. Anyway I understand your pain & your frustration and you know that the folks on this board will listen to you anytime. Good Luck & God Bless
