Published on: June 17, 2015
Summary
Laboratory animal tests effectively predict human carcinogens, offering a reliable method for cancer prevention. Critically examined, the perceived flaws in these tests are insignificant, supporting their use in public health.
Area of Science:
- Toxicology
- Carcinogenesis
- Public Health
Background:
- Predicting human carcinogens is crucial for public health and cancer prevention.
- Laboratory animal testing is a primary method for identifying potential carcinogens.
- Concerns regarding the validity and application of animal carcinogenicity tests persist.
Purpose of the Study:
- To critically evaluate the effectiveness and limitations of laboratory animal tests in predicting human carcinogens.
- To address common criticisms and misconceptions surrounding animal carcinogenicity studies.
- To assess the public health implications of using animal test results for regulatory decisions.
Main Methods:
- Analysis of scientific literature on animal carcinogenicity testing and human epidemiological studies.
- Critical examination of data regarding false positives and the impact of high-dose testing.
- Review of regulatory actions and cost-benefit analyses related to carcinogen identification.
Main Results:
- Laboratory animal tests are effective in identifying potential human carcinogens, enabling preventative measures.
- Common criticisms, such as false positives from high-dose testing, are not scientifically supported.
- All known human carcinogens are identified as carcinogenic in animal models.
- Epidemiological data largely corroborate findings from animal studies for chemicals with human exposure.
- Economic arguments against regulations based on these tests are often based on overestimated costs.
Conclusions:
- Laboratory animal testing is a scientifically sound and valuable tool for protecting public health from carcinogens.
- The predictive value of animal carcinogenicity studies for human cancer risk is high.
- Continued reliance on and refinement of animal testing are essential for effective carcinogen identification and risk management.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:12What is Cancer?
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

01:25Mutagenicity and Carcinogenicity
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
