Went to the Doc today, he's of the opinion that the 3mm growth is beyond the margin for error, and that it IS growing. Gave me three options, a further 4 month wait MRI, Gamma Knife, or Surgery. Of course I already knew that was the options.
He said that the symptoms I have probably are there for good, so I'm thinking go ahead and kill this thing one way or another before it grows further and the symptoms progress. After all the pluses and minuses were presented, I'm leaning hard toward the GK. He referred me to another doctor who apparently deals with GK: I haven't yet set an appointment date but have a call into his office: hopefully that will happen tomorrow.
He didn't really push me toward one or the other, (despite being a surgeon himself) but here's my reasoning:
1. the obvious outpatient treatment of GK vs. some significant downtime for surgery
2. He mentioned a slight possibility of recurrence with GK, as opposed to surgery, and that surgery on once-irradiated tissue being more complicated than just doing it the first time around. I'm thinking that my odds are fairly good against that to begin with, and that surgery in several years may be more advanced than surgery now, and I may be in a better position to take a month or two off at the time.
3. side-effects and possible side-effects of major surgery vs. the GK: unless there's something I missed, I like my odds better with the GK.
Any thoughts on those developments?
