Chromium is an essential trace element, but high concentrations are toxic and carcinogenic. This study reviews chromium

Area of Science:

  • Environmental Toxicology
  • Molecular Biology
  • Carcinogenesis

Context:

  • Essential trace element with dual role: deficiency causes dysfunction, excess causes toxicity.
  • Epidemiological studies confirm chromium carcinogenicity, with Cr(VI) classified as a known carcinogen by IARC.
  • This work reviews epidemiological findings and delves into molecular mechanisms of chromium-induced cancer.

Purpose:

  • To review epidemiological evidence of chromium carcinogenicity.
  • To analyze the molecular mechanisms underlying chromium's carcinogenic effects.
  • To discuss methods for assessing chromium's mutagenicity and genotoxicity.

Summary:

  • Reviews epidemiological data on chromium exposure and cancer.
  • Explores molecular aspects of chromium carcinogenicity, including DNA damage.
