The tumor that was removed from my cerebellum turns out to have been denign (as was expected). It was a known quantity and as such I will make a full recovery from it, with no chance of return. Of course, as Walt Kelly says: "You shouldn't take life to seriously, because it is in no case permanent." but still it is nice to hear it out loud from a man in a white coat.
I am not going to spend all evening telling everyone about my good fortune, so feel free to spread the word. Next time, more pretty pictures.
