Hi Stacy,
I have to agree with Jamie. Please keep in mind that the radiation that is used for CK or GK is not a "disposable" radiation, thus, cancer scare is really not legit. Many surgeons steer clear of noting radio-surgery options and vice versa. Just seems to be a tactic used by many.
Many AN'ers will report a shrinkage in their AN size post radio-surgery treatments. My last MRI showed no further growth (mine was growing at a good rate). Yes, the once the AN is "killed" by the radio-surgery, it does remain there, but the DNA of the AN is dead, thus, no further growth. As we know, there are no guarantees in life, but the chances of the tumor growing further is practically non-existant.
Your dad does sound like a terrific radio-surgery candidate, based on his age, the size of the growth, etc. In speaking to many here, it's just a personal decision, keeping in mind all of his lifestyle issues. Questions I would ask (if I were your dad) are:
1. Should I try non-invasive vs. invasive?
2. Am I confortable knowing that the AN would remain dead there vs. get this thing outta my head?
3. What are potential after affects with all forms of treatments?
4. How experienced is the team that will treat me (regardless if surgical or radio-surgery)
There are many more questions to be asked, but these are just a few that I asked myself as I began my decision making process. Many here that have had micro-surgery maintain full, productive lives... same as many radio-surgery patients. Some outcomes are not as good as hoped. As with any medical situations, there can be the good, the bad and the ugly. You have a wealth of information available here in these forums to help further educate.
Anything I note here, please note it's only worth my 2 cents. Hang in there... your dad is going to be fine!
