<unk> s (CSF) are used to estimate the risk of<unk>  associated with exposure to a carcinogenic or potentially carcinogenic substance. A<unk><unk>  is an upper bound, approximating a 95% confidence limit, on the increased<unk>  risk from a lifetime exposure to an agent by ingestion or inhalation. This estimate, usually expressed in units of proportion (of a population) affected per mg of substance/kg body weight-day, is generally reserved for use in the low-dose region of the dose-response relationship, that is, for exposures corresponding to risks less than 1 in 100.<unk><unk> s are also referred to as<unk>  potency<unk> s (PF).
