[Histonet] Carcinogenic materials

[Laurie Colbert]

Does anyone know of some kind of reference book that lists which chemicals are carcinogenic?  Even in checking specific MSDS I find conflicting information.  What does it mean on the MSDS when it says "N/A" or "Not Available" next to the carcinogenicity data - is the chemical NOT carcinogenic or maybe it is and it's not listed?
