INTRODUCTION

This data library is integrating information about brain tumors on the internet. It will also communicate with neurosurgeons, neuropathologists and doctors of related areas. Everybody can participate. Since there is not a rule at all, an interesting case, an unusual case and a typical pretty case will be accepted. I will carry it with pleasure. However, images which have a copyright of publication are not accepted. Then please show me an information about a new brain tumor web. I will willingly link it. Please send me (amagasa@cup.com) a mail. Lurking is no good.
