The pathology on the tumor confirmed the preliminary diagnosis. It's definitely a Medulloblastoma.
Because he's so young, they can't really use radiation therapy which would otherwise be the norm for a tumour in the brain, instead they'll treat with chemo which has a lower success rate. It lowers his odds of beating the cancel from 80% to 50% on the chemotherapy.
He'll start chemotherapy treatments in 3 weeks.
In good news, they took the stomach drain out yesterday and he got to eat a little bit and walk around a little more.
In less good news, he suffered 2 seizures and will have to take anti-seizure medication for 6 months.
