Excerpt: There is a massive amount of such chemicals, but scientists still need to research their carcinogen potential, according to a report by the President's Cancer Panel.

People are exposed to a massive number of chemicals in the environment, and scientists know very little about their potential role in causing cancer, according to a new report from the President's Cancer Panel released Thursday.

Government and industry should invest much more money in researching the potential risks of such chemicals — and that research should be done before the chemicals come into wide use, not after large numbers of people have been exposed to them, the report said.
