well I finally found the name and spelt correctly, my docotr wrote it down for me to research it. Its called astrocytoma
I also found somewhere on wikipedia about it that has some quite good and relevant information, and yes like normal im one of those rare cases.
It says the normal age for diagnosis is 12, no wonder my parents wouldnt beleive ive had it for years. they dont read facts. Funny enough my parents thought my constant vomiting was because i didnt want to eat my green vegetables and was an excuse, and all along my tumor was causing it.
