The NTP classifies lead and lead compounds as "reasonably anticipated to be human carcinogens," based on limited evidence from studies in humans and sufficient evidence from studies in lab animals. The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO).
Known and Probable Human Carcinogens. Many people worry that substances or exposures in their environment may cause cancer. As part of the American Cancer Society’s role in informing and educating people about cancer and its possible causes, this document provides lists of substances and exposures that are known or suspected to cause cancer.
Carcinogens may increase the risk of cancer by altering cellular metabolism or damaging DNA directly in cells, which interferes with biological processes, and induces the uncontrolled, malignant division, ultimately leading to the formation of tumors. Usually, severe DNA damage leads to programmed cell death, but if the programmed cell death ...
More cases of lung cancer are found in cities and urban areas where air pollution levels are considered unsafe. Occupational hazards apply to people that work with known cancer-causing carcinogens such as asbestos, lead, benzene, and vinyl chloride. Where you work and where you live make up a large portion of your daily life.
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".The exposure circumstance entails exposures that are possibly carcinogenic to humans.

A Carcinogen is defined as any substance, radionuclide, or radiation that is an agent directly involved in causing cancer. This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their ...
Exposure to lead can happen from breathing workplace air or dust, eating contaminated foods, or drinking contaminated water. Children can be exposed from eating lead-based paint chips or playing in contaminated soil. Lead can damage the nervous system, kidneys, and reproductive system. Lead has been found in at least 1,026 of 1,467 National Priorities List sites identified by the Environmental ...
Lead is a naturally occurring bluish-gray metal found in small amounts in the earth's crust. It has no characteristic taste or smell. Metallic lead does not dissolve in water and does not burn. Lead can combine with other chemicals to form what are usually known as lead compounds or lead salts. Some lead salts dissolve in water better than others.
Carcinogens are agents that can cause cancer. In industry, there are many potential exposures to carcinogens. Generally, workplace exposures are considered to be at higher levels than for public exposures. Safety data sheets (SDSs) should always contain an indication of carcinogenic potential.
