Carcinogenicitetsvurdering

Carcinogenicitetsvurdering, or carcinogenicity assessment, is the scientific process used to evaluate the potential of a substance to cause cancer in humans or animals. This assessment is a critical component of public health and safety regulations, guiding decisions on the approval, restriction, or banning of chemicals, pharmaceuticals, and other substances.

The process involves the systematic review of existing scientific data, including epidemiological studies, animal testing results, and mechanistic studies that explore how a substance may induce cancer. Regulatory agencies such as the International Agency for Research on Cancer (IARC), the Environmental Protection Agency (EPA), and the European Chemicals Agency (ECHA) utilize these data to classify substances based on their carcinogenic potential. Classifications typically range from "not classified" to "probably carcinogenic" or "carcinogenic to humans."

Key steps in carcinogenicitetsvurdering include hazard identification, dose-response assessment, exposure assessment, and risk characterization. Hazard identification determines whether a substance has the potential to cause cancer, while dose-response assessment evaluates the relationship between exposure levels and cancer risk. Exposure assessment quantifies how much and how often humans or environments are exposed to the substance. Risk characterization then integrates this information to estimate the likelihood of adverse effects under specific exposure scenarios.

Carcinogenicitetsvurdering informs regulatory measures to protect public health, such as setting permissible exposure limits, labeling requirements, and usage restrictions. It also guides research priorities by highlighting substances that require further investigation. Due to the complexity and evolving nature of scientific knowledge, carcinogenicity assessments are regularly updated to reflect new evidence and improve safety standards.
