Children Exposed To Pesticides Have Higher Risk of Cancer: Study

Children exposed to indoor pesticides may be nearly 50% more likely to be diagnosed with childhood cancer, according to the findings of a new study. 

Researchers with the Harvard T.H. Chan School of Public Health in Boston found higher rates of childhood leukemia and lymphoma when they looked at a number of previous studies on pesticide exposure. The findings were published by the medical journal Pediatrics on September 14.

The analysis looked at 16 previous observational studies published before February 2014. According to the findings, there was a 47% increased risk of a child being diagnosed with childhood leukemia, and a 43% increased chance of a childhood lymphoma diagnosis if the child was exposed to indoor herbicides, but there was no link found to outdoor exposure.

Researchers also found a slightly increased risk of childhood brain tumors, but the risk was deemed too small to be statistically significant.

“Results from this meta-analysis indicated that children exposed to indoor insecticides would have a higher risk of childhood hermatopoietic cancers,” the researchers in the latest study determined. “Additional research is needed to confirm the association between residential indoor pesticide exposures and childhood cancers. Meanwhile, preventative measures should be considered to reduce children’s exposure to pesticides at home.”

A number of other recent studies have linked pesticides to developmental problems both from exposure during pregnancy and in childhood.

The latest findings come just two months after a study published in Environmental International found that exposure to some insecticides appeared to increase the risk of impaired brain development in children.

A study published in June 2014 in Environmental Health Perspectives linked exposure to pesticides during pregnancy to an increased risk of autism.

Another study also published in the Environmental Health Perspectives revealed pregnant women exposed to pesticides may have premature deliveries and children with lower birth weights.

That study focused on exposure to organophosphates and linked exposure to birth weights one-third pound lighter and several days earlier than expected.

A Harvard study published in 2010 revealed a link between pesticides and the development of attention deficit hyperactivity disorder (ADHD). Children with higher levels of organophosphates in their urine were more likely to be diagnosed with ADHD.

About 40 organophosphates are used in the U.S., with nearly 73 million pounds used in 2001 alone.

In light of concerns over pesticide health risks, the U.S. Environmental Protection Agency (EPA) recently proposed new pesticide exposure rules. The rules focus on improved worker training, prevention and pesticide treatment measures.

It is a FLAWED STUDY that made a FAILED attempt to establish some kind of link between the development of childhood CANCERS, primarily leukemia and lymphoma, and the use of pest control products. The study DID NOT perform any new research, but rather, did a META-ANALYSIS ( a.k.a. RETROSPECTIVE ) of a combination of 16 previous studies that examined whether there was a correlation between these cancers and exposure to the ingredients that are found in INSECT ICES sprays. Their conclusion ?!?! Children who were exposed to insect spray indoors APPEARED to have about a 45 per cent increased risk of developing leukemias and lymphomas. According to American Council for Science and Health ( ACSH, see below ), there all sorts of FLAWS in the study. Retrospective studies are NOTORIOUSLY UNRELIABLE. Although a 45 per cent increase seems like a substantial number, it is not for retrospective studies. In a retrospective study, any effect that is not at least DOUBLE ( 100 per cent increase ) is MEANINGLESS. Moreover, many of the active ingredients reported in this flawed-study are CHEMICALLY AND PHARMACOLOGICALLY UNRELATED TO EACH OTHER. It is a FALLACY to assume that any two of these ingredients will have similar effects upon humans simply because they both kill INSECTS. This flawed-study does not even attempt to distinguish which insecticides were associated with these cancers, but rather, AMATEURISHLY LUMPS THEM ALL TOGETHER. This COMPROMISES any conclusions that are derived from this flawed-study. Finally, some kind of link was supposedly found with the use of HERBICIDES. This is SCIENTIFICALLY ABSURD. The ingredients that are used to control weeds have NOTHING WHATSOEVER IN COMMON with those that control INSECTS, either chemically or mechanistically. THIS IS A HUGE RED FLAG THAT SUGGESTS THAT THE DATA ARE MEANINGLESS. Consequently, Chensheng Lu’s Anti-Pesticide Study has been DISCREDITED. Scientific research shows that, as reported through EPA’s and Health Canada’s vast toxicology database, NO harm will occur when pest control products are applied properly. All of these products have been evaluated for their carcinogenic potential. http://wp.me/p1jq40-6yf Even Canadian Cancer Society’s own web-sites state, repeatedly, that scientific research does NOT provide a conclusive link between pest control products and cancer. http://wp.me/p1jq40-4qc In fact, scientific research proves that pest control products will cause NO harm and do NOT cause cancer. PESTICIDES CAUSING CANCER IS A MYTH ! http://wp.me/p1jq40-2nl The safety and effectiveness of pest control products is NOT a debatable issue. Overwhelming scientific research has clearly demonstrated that that have NOT been linked to ANY issues related to health and environment. There are thousands of known deaths per year from known cancer-causing factors such as unhealthy diet, physical inactivity, excess body weight, alcohol consumption, and over-exposure to the sun. There are NONE related to pest control products, which are SCIENTIFICALLY-SAFE, and will NOT CAUSE HARM TO PEOPLE, ANIMALS, OR THE ENVIRONMENT. http://wp.me/p1jq40-7HR http://wp.me/P1jq40-2ha http://wp.me/p1jq40-5ni American Council for Science and Health ( ACSH ) is a non-profit organization founded in 1978 by Dr Elizabeth M Whelan that produces peer-reviewed reports on issues related to food, nutrition, chemicals, pharmaceuticals, lifestyle, the environment, and health ACSH frequently defends science against claims that industry products create risks of injury, ill-health, or death. Consequently, ACSH has been entered on the list of REAL experts who speak out against the conspiracy to impose reckless and arbitrary prohibition against conventional pest control products. http://wp.me/P1jq40-8hT For more information about ACSH, go to The Pesticide Truths Web-Site ... http://wp.me/P1jq40-1XS We are the National Organization Responding Against HUJE that conspire to destroy the Green space and other industries ( NORAH G ).
