Quick Answer: What kind of cancer is caused by lead?

Lead exposure has been associated with increased risk of lung, stomach, and urinary-bladder cancer in diverse human populations. The strongest epidemiological evidence is for lung and stomach cancer, which are consistently but weakly associated with occupations and industries entailing lead exposure.

What types of cancer does lead cause?

Background: Lead is only weakly mutagenic, but in vitro it inhibits DNA repair and acts synergistically with other mutagens. Lead acetate administered orally, cutaneously, or intraperitoneally causes kidney cancer, brain cancer (gliomas), and lung cancer in rodents, and acts synergistically with other carcinogens.

Which disease is caused by lead?

People with prolonged exposure to lead may also be at risk for high blood pressure, heart disease, kidney disease, and reduced fertility.

Is lead a known carcinogen?

The Department of Health and Human Services (HHS) has determined that lead and lead compounds are reasonably anticipated to be human carcinogens (causing cancer in people). The U.S. Environmental Protection Agency (EPA) has classified lead as a probable human carcinogen.

Does lead poisoning cause leukemia?

The most convincing evidence is for lead, as two studies have shown that paternal occupational exposure to lead is associated with childhood acute myeloid leukemia (Buckley et al., 1989) and ALL (Miligi et al., 2013).

How long can lead stay in your body?

Once in the body, lead travels in the blood to soft tissues such as the liver, kidneys, lungs, brain, spleen, muscles, and heart. The half-life of lead varies from about a month in blood, 1-1.5 months in soft tissue, and about 25-30 years in bone (ATSDR 2007).

How toxic is lead?

Lead exposure can have serious consequences for the health of children. At high levels of exposure lead attacks the brain and central nervous system, causing coma, convulsions and even death. Children who survive severe lead poisoning may be left with intellectual disability and behavioural disorders.

Can your body get rid of lead?

The damage lead causes cannot be reversed, but there are medical treatments to reduce the amount of lead in the body. The most common is a process called chelation – a patient ingests a chemical that binds to lead, allowing it to be excreted from the body.

Can you recover from lead poisoning?

What is the outlook for lead poisoning? Adults with moderate exposure usually recover without any complications. In children, recovery can take time. Even low lead exposure can cause permanent intellectual disability.

What foods are high in lead?

Lead was most commonly found in the following baby foods types:

  • Fruit juices: 89% of grape juice samples contained detectable levels of lead, mixed fruit (67%), apple (55%), and pear (45%)
  • Root vegetables: Sweet potatoes (86%) and carrots (43%)
  • Cookies: Arrowroot cookies (64%) and teething biscuits (47%)

How long does it take to get lead poisoning?

Lead poisoning usually takes months or years of exposure to a small amount of lead at home, work or daycare. When exposed to large amounts of lead, it can quickly lead to lead poisoning (acute poisoning).

Does lead cause reproductive harm?

Lead is on the Proposition 65 list because it can cause birth defects or other reproductive harm. Exposure to lead during pregnancy can affect brain development and cause learning and behavior problems for the child. Exposure to lead can harm the reproductive systems of men and women.

Why is lead a carcinogen?

Plausible mechanisms of lead carcinogenicity include direct DNA damage, clastogenicity, or inhibition of DNA synthesis or repair. Lead may also generate reactive oxygen species and cause oxidative damage to DNA.
