Subject: Brain Tumor Statistics: How to Determine if a Cluster Exists

Here is where the cluster of brain tumors is suspected.

Here is a page I found about brain tumors:

http://www.tbts.org/itemDetail.asp?categoryID=384&itemID=16535

The second link says that there is about a 0.6% lifetime chance of a person
developing a brain tumor. If you use the town population of 6500 and multiply by
(0.006 / 72 years average lifetime), you get less than 1 person (about 0.54 of a
person) getting a brain tumor in this population's entire lifetime.

Does that calculation sound right? If so, they really DO have a major problem,
these 12 tumors have appeared in the last 7 months, the article says.
