Re: AW: Further thoughts on carcinogens
My guess is that the Ames Test was the standard of the
times.

As our biological knowledge grows, better tests will
be developed.

However, I wonder if such types of tests are really
valid. If mutations occurs in one test animal or cell
line, does that mean that the substance will cause
cancer in humans? Is there really an absolute
correlation?
