is lead a carcinogen

Cadmium compounds are classified as human carcinogens by several regulatory agencies. eCollection 2020. This site needs JavaScript to work properly. May cause cancer based on animal information. This mirrors the 2001 IARC finding that extremely low frequency (ELF-EMF) that classified as a 2B (Possible) Carcinogen. In pathology, a carcinogen is any substance or agent that promotes cancer. Cancer is a complex group of diseases with many possible causes. Lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. Public health risk of heavy metal residues in meat and edible organs of broiler in an intensive production system of a region in Pakistan. Lead exposure has been associated with increased risk of lung, stomach, and urinary-bladder cancer in diverse human populations. In the EU 1.5 million workers are estimated to be potentially exposed to lead and inorganic lead compounds. It can be used as a pure metal, combined with another metal to form an alloy, or in the form of a chemical compound. Six of the eight studies cited above have been published since 1987. Lead fumes are produced during metal processing, when metal is being heated or soldered. IARC Monographs on the Identification of Carcinogenic Hazards to Humans. Links with this icon indicate that you are leaving the CDC website.. Lead compounds do not appear to cause genetic damage directly, but may do so through several indirect mechanisms, including inhibition of DNA synthesis and repair, oxidative damage, and interaction with DNA-binding proteins and tumor-suppressor proteins.  |  [Theory and practice of primary cancer prevention]. 2020 Apr;27(10):10147-10159. doi: 10.1007/s11356-020-07989-w. Epub 2020 Feb 14. A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis, the formation of cancer.This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Carcinogenic definition is - producing or tending to produce cancer. Even low-level lead exposures in developing babies have been found to affect behavior and intelligence.  |  The most common route of occupational exposure to lead is inhalation of lead fumes or lead-laden dusts in air and absorption of lead through the respiratory system. Clipboard, Search History, and several other advanced features are temporarily unavailable. Lead (Pb), a toxic heavy metal, is capable of inducing several adverse health effects following its accumulation in the body. Loading… Thus the mechanisms of lead carcinogenicity are unlikely to be fully explained as toxicity‐related sequelae of high dose exposure or as a rat‐specific response involving overexpression of a renal protein. The U.S. Environmental Protection Agency (EPA) has classified lead as a probable human carcinogen. 2001 Jun 12;273(1-3):77-82. doi: 10.1016/s0048-9697(00)00843-3. Lead is classified as Group 2B carcinogen by the IARC, meaning it is probably carcinogenic to humans. In this section you can learn more about the known causes of cancer, including genetic factors; lifestyle factors such as tobacco use, diet, and physical activity; certain types of infections; and environmental exposures to different types of chemicals and radiation. For linear carcinogens, EPA's current process of estimating cancer risk is based on the unit risk estimate (URE) for inhalation, and the carcinogenic potency slope (CPS) for ingestion. The precise mechanisms by which lead causes cancer are unknown. Background: Lead is only weakly mutagenic, but in vitro it inhibits DNA repair and acts synergistically with other mutagens. Substances, mixtures and exposure circumstances in this list have been classified by the International Agency for Research on Cancer (IARC) as Group 2B: The agent (mixture) is "possibly carcinogenic to humans". Occupational Lead Exposure and Brain Tumors: Systematic Review and Meta-Analysis. However, the lung cancer findings are not consistent across studies, and confounding by arsenic may affect the study with the highest lung cancer RR. List of Classifications. A carcinogen is something that can cause you to have cancer. 2019 Sep;76(9):603-610. doi: 10.1136/oemed-2019-105786. The strongest epidemiological evidence is for lung and stomach cancer, which are consistently but weakly associated with occupations and industries entailing lead exposure. Organolead compounds are not classifiable as to their carcinogenicity to humans (Group 3) . 2007;37(10):887-914. doi: 10.1080/10408440701638970. IARC classified lead as a "possible human carcinogen" based on sufficient animal data and insufficient human data in 1987. In this section you can learn more about the known causes of cancer, including genetic factors; lifestyle factors such as tobacco use, diet, and physical activity; certain types of infections; and environmental exposures to different types of chemicals and radiation.
