Hi,
As others have said, we are sorry to hear of your dad's diagnosis, but we're glad you found this support group. Even though we're not there in Singapore with you, the internet allows us this truly wonderful group of sympathetic and researching ANers!
Both my mother and my husband had brain surgeries after age 65, my mother to clip aneurysms, my husband to remove a large benign brain tumor on the medula. My best advice is probably unnecessary, but I will repeat it anyway: Be AVID patient advocates for your dad. Be at the hospital ALOT. The more you're there, the more the staff does good work. I don't say this cynically -- medical staff usually treat all patients well, BUT it's just human nature that the more you're there, the more attention they pay to your dad's needs, and the more you can monitor what's going on.
The other piece of advice is to try to create as healing an environment for your dad as possible when he's in the hospital. By this I mean, make sure he gets normal sleep cycles, lights out or curtains shut. The older we are, the more difficult it is for the body to recover. All the help the body can get is best.
You might have to be persistent. I was always kind and courteous, but very persistent when I wanted something to happen. I encourage you to be the same.
The only other little comment I add is to make sure you and your dad are aware that the radiation required after the tumor is debulked in NOT the radiation that is used for many other growths. That is, it's NOT generalized and does not make your body feel sick. It's either a one-day (GammaKnife) or a several-single-day (CyberKnife) procedure that is not that hard on the body. I just wanted to make sure you were aware of that, so you know that after he's recovered from the microsurgery, he does NOT have to look forward to any discomfort.
Take care and let us know how things progress -- and please let your dad know that we're all thinking of him.
Dana
