Can formaldehyde cause cancer? Exposure to formaldehyde has been shown to cause cancer in laboratory test animals. Exposure to relatively high amounts of formaldehyde in medical and occupational settings has been linked to some types of cancer in humans, but the effect of exposure to small amounts is less clear. Studies in the lab
While some studies have indicated an excess of cancer in exposed individuals or Mechanisms involved in the carcinogenicity of formaldehyde, such as the
However, the linear unit risk approach that is based on conservative ("worst-case") considerations is also used for risk characterization of formaldehyde exposures.

The expert working group at the International Agency for Research on Cancer has determined that there is now sufficient evidence that formaldehyde causes nasopharyngeal cancer in humans, a rare cancer in developed countries 31).

Extended follow-up of a cohort of British chemical workers exposed to formaldehyde. J Natl Cancer Inst 21:1608-1614 14600093. For these reasons and others—such as its role as a suspected human carcinogen linked to nasal cancer and lung cancer 578, this germicide is excluded from Table 1. When it is used, , direct exposure to employees generally is limited; however, excessive exposures to formaldehyde have been documented for employees of renal transplant units 574, 579 , and students in a gross anatomy laboratory 580 .
and mechanisms of carcinogenesis.
Formaldehyde is a colorless, strong-smelling chemical used in building materials and many household products, and as a preservative in funeral homes and medical labs. Learn what we know about formaldehyde and cancer risk here.
This risk assessment uses data on target tissue dosimetry, size of the target cell population in the rat nasal epithelium, number and size of putative preneoplastic lesions, and tumor incidence. Cellular proliferation increases considerably at concentrations > 6 ppm and amplifies the genotoxic effects of formaldehyde. The working group concluded, “The current data indicate that both genotoxicity and cytotoxicity play important roles in the carcinogenesis of formaldehyde in nasal tissues.”. Cancer (IARC) announced that formaldehyde was deemed to be a human carcinogen following a reassessment (sufficient evidence that formaldehyde causes nasopharyngeal cancer in humans).

It is a known carcinogen, according to both the International Agency for Research on Cancer (IARC) and the National Toxicology Program (NTP), which evaluated the evidence in support of a causal connection between formaldehyde exposure and nasopharyngeal cancer. The chemical enters the body most commonly through inhalation of formaldehyde gas or vapor. A planned mechanism-based risk assessment for formaldehyde is then described. This risk assessment uses data on target tissue dosimetry, size of the target cell population in the rat nasal epithelium, number and size of putative preneoplastic lesions, and tumor incidence.
These data establish parameter values for a biologically based, multistage cancer model that is then used to predict cancer risk at low exposure levels. Accumulation of formaldehyde in cancer cells is combined with activation of the processes of cellular formaldehyde clearance. These mechanisms include increased ALDH and suppressed ADH5/FDH activity, which oncologists consider poor and favorable prognostic markers, respectively. Here, the sources and regulation of formaldehyde metabolism in cancer cells are reviewed.
