 brain tumor surgery, how does it affect the personality / psyche

i wonder at what degree the personality of a person is being altered having a brain tumor removed.
as i understand this, the operation and everything definitely leaves a trauma itself and also tehre is the piece of removed tissue.
correct me if i am wrong here, but the tumor as it grows "munches" on the brain and grows right ?
so it actually bilds up tissue somewhere.
given that tumor gets removed, are also parts of the brain removed which changed the way the person is ?
how he behaves, thinks, logik, ego , emotions you get the idea.
reason i ask is i know someone who is bright and nice and he told me of havnig had brain surgery some years back.
and so i wonder.
did the surgery turn him into somebody else ?

I don't think there's a good answer to your question. THere are a lot of variables to consider. One major factor would be the area of the brain affected (different brain regions are involved in different functions). Then you would have to consider the size of the tumor, how much tissue is removed, etc. etc.
I think you would have to remove a relatively large portion of the brain to get any significant effects.

hmm yeah.
in my studies i learned if parts of the brani resposible for one task fail and get removed at early stages,
other parts of the brain can adapt and do its job.
not sure how that's the case when the person was ~16 when the tumor was removed.

They have shown that the occipital lobe, in adults that loose their eyesight, will start to process different information.

Great reads, and there are so many things than can happen to a person when something goes wrong in the brain.

it depends in what area of the brain the tumor is. does the surgeon have to cut trough a lot of brain tissue etc

it doesn't munch on the brain but is fed trough bloodvessels, just like any other part of the body. it can push brain tissue aside or 'crush' it with the pressure it gives.

yes

how he behaves, thinks, logik, ego , emotions you get the idea.
again it completely depends on the location of the tumor, if it has done any damage and how difficult it is to remove it etc.

probably not, but it is possible. you should ask him, or people who know him for longer than that 
if you have any more questions about brain-things hit me up with a pm. I study neuropsychology so I know a lot about the brain

the brains plasticity is really amazing.
for example if you loose a finger, the brain area for movement of that finger will be 'taken over' by surrounding brain areas of the other fingers.

unfortunately this isn't the case. sometimes minor damage in crucial areas can have major effects.

But the reverse is also true. Sometimes people can loose huge amounts of brain matter and still function relatively fine.

Every one has already said it, but it just depends on how soon the tumor is found and where it is.
I had a friend in high school who had a brain tumor. He was so cool and such a bad ass. Chicks wanted him, guys wanted to be him. He was amazing on the skateboard as well as with a pen/pencil. After he had his surgury he was a completely different person. He was very slow, shakey, it took a couple of years for him to be able to walk. I think he probably still has a cane. It was really sad.

This is one of the more famous accounts of brain damage and personality changes. It's an elementary section of most psych. classes.
http://bmj.bmjjournals.com/cgi/content/full/317/7174/1673/a
This is why "how much" is a subjective term when asking how much damage needs to occur.
