Hi; I am 9-months post-op, and have done very, very well every since surgery.
Because of the size of my tumor (4cm) surgery was pretty much my only option; though after doing lots of research I would have chosen it, anyway. With radiosurgical treatments, if there is future re-growth surgery becomes more difficult, as radio treatments damage surrounding healthy tissues. Also, there is no data beyond 10 years on theses treatments. However, everyone has a right to evaluate and choose whatever option they wish. I had an extremely successful surgery; every bit of my tumor was removed and I had no facial nerve damage at all. I did lose the hearing in one ear, but it was almost gone anyway.
Yes, there is a lot of scary information on the internet. But keep looking; there are many, many success stories as well. Try to imagine that those of us who are doing great are out rock-climbing, etc., too much to sit at our computers all that much!
I, too, have always been a very active person. My physical condition and enjoyment of challenging myself have been creditted with playing a large part in my "phenomenal" recovery. A positive mental attitude, loving and supportive family & friends, and excellent doctors are also big factors.
Generally, there is no huge rush to treatment as these tumors grow very slowly. How large is yours? Of course, this diagnosis is quite stunning and waiting for answers is very difficult. I waited 10 weeks between diagnosis and surgery, and I spent that time organizing my home/family/work situations for my absence as well as hiking, running, and basically "training" for the upcoming ordeal.
A doctor who does not provide you with information or makes you wait a long time for answers would raise my eyebrows; insist on a response or find someone else.
To answer your questions regarding post-surgical timeframes, in my case things went something like this:
5 days-home from hospital
2 weeks-4 mile walk, working part-time, back to caring for my horses
3 weeks-driving, ballet class (yup, that's what I said!)
4 weeks-mountain hiking
7 weeks-putting on Thanksgiving Dinner for my extended inlaws (you have no idea how much this counts for!!)
Good luck, stay positive, and keep exercising. We'll stay in touch!
