Our 6 1/2 year old son Colby Arnett had been having migraines. After MRI we discovered it was a brain tumor. The amazing surgeons at UCSF removed the tumor, however, we have discovered that it's cancerous. We will be beginning 6 weeks of radiation and chemotherapy simultaneously five days a week in San Francisco - followed by chemotherapy for 6-8 months. We have a long tough road ahead of us... more than any six year old  should have to endure.
