RE: Source of cancer data

["Bolling, Jason E" <bollingje@ports.usec.com>]

As a generally passive observer to the LNT arguments, I have only my limited

common sense to rely on.  However, it would seem to me that if you are

interested in whether or not something causes cancer, you would want to know

all the cases of cancer, NOT just the cases where somebody died of cancer.

After all, we are getting better at treating cancer, I think, so cancer

mortality per capita should be going down just based on our increased

knowledge of how to deal with it.



So, I guess which data you use depends on what you are trying to

investigate.  Do you want know whether people have died of cancer due to a

specific cause... or do you want to know if people get cancer because of a

specific cause?  The question should dictate which set of data is "better".
