DDT Exposure During Early Life Associated with Increased Risk of Breast Cancer  (Beyond Pesticides, February 20, 2019)   'Women exposed to DDT during ‘early windows of susceptibility’ in their childhood are at increased risk of developing breast cancer, according to new research published in the Journal of the National Cancer Institute..These studies, and the predictable lag time between exposure, health impacts, and epidemiological data on those impacts should lead lawmakers and regulators to consider taking a more precautionary approach to the introduction of these chemicals into the environment.'

Dr. Wozniak: Roundup Damages DNA in Human Blood Cells at Low Concentrations (publishd in Food and Chemical Toxicology, July 2018) with link to original article. DNA damage induced by glyphosate and its derivatives increased in order: AMPA, glyphosate, Roundup 360 PLUS. AMPA is the degradation product of glyphosate. The formulation Roundup 360 PLUS was toxic at 50 times lower concentration than glyphosate alone. For regulatory purposes, a pesticide is tested by itself, never as a formulation. Acceptable levels are also based on single pesticide testing, and not on its increased toxicity in formulation. 

Neonicotinoids may alter estrogen production in humans (INRS,April 26, 2018,/ by Stéphanie Thibault)   An INRS team publishes the first-ever in vitro study demonstrating the potential effects of these pesticides on human health in the journal Environmental Health Perspectives. The results of the study show an increase in aromatase expression and a unique change in the pattern in which aromatase was expressed, which is similar to that observed in the development of certain breast cancers. (also filed under neonicotinoids)

Harvard Meta-Analysis Ties Childhood Cancer to Pesticide Use (Beyond Pesticides, September 15, 2015) A study released this week in the journal Pediatrics finds that children’s exposure to pesticides in and around the home results in an increased risk of developing certain childhood cancers... For example, while residential herbicide use was associated with an increased risk of leukemia, the link between outdoor insecticide use and childhood cancers was not found to be statistically significant. However, exposure to insecticides inside the home was significantly associated with an increased risk of childhood leukemia and lymphoma.

Popular weedkiller may cause cancer, World Health Organization agency says Ariana Eunjung Cha / The Washington Post, 6 July 2015. 2,4-D, sprayed widely on farms and used in a number of popular lawn-care products has been designated as "possibly" carcinogenic to humans by a World Health Organization research arm. 2,4,5-T was the main part of Agent Orange containing a lot of dioxins and has been banned for a while. but 2,4-D contains dioxins too. However, they are not the kind companies have to report on, so are not regularly measured. More on 2,4-D and dioxins under registration and re-evaluation.

Media and NGO comments on WHO classification of glyphosate as probable carcinogen (GM Watch. 02 April 2015). However, unless the EPA reforms its evaluation processes, it will not take the WHO report (GM Watch,March 20, 2015) into serious consideration.

Review Links Glyphosate to non-Hodgkin’s Lymphoma (Beyond Pesticides, May 2, 2014 The study represents one of the most comprehensive reviews on the topic of occupational exposure to pesticides in scientific literature, demonstrating their clear harm to human health. In addition to linking glyphosate to non-Hodgkin’s lymphoma, the researchers also found that carbamate insecticides, organophosphate insecticides, phenoxy herbicide MCPA, and lindane were positively associated with NHL cancer.

Triclosan Linked to the Growth of Breast Cancer Cells (Beyond Pesticides, April, 29, 2014) as well as octylphenolTriclosan is an antibacterial and antifungal agent found in numerous commonly known household products. Octylphenol is a commercial solvent that can be found in paints and plastics, and is often used as an inert ingredient in pesticide formulations in the U.S, but not listed in Canada (List of Formulants 2010). Both chemicals are also endocrine-disrupting.

Other associations with benomyl and ever use of arsenical pesticides were also suggested. (June 2010)

Association of Frequency of Organic Food Consumption With Cancer RiskFindings From the NutriNet-Santé Prospective Cohort Study (JAMA Internal Medicine, October 22, 2018)  High organic food scores were inversely associated with the overall risk of cancer (hazard ratio for quartile 4 vs quartile 1, 0.75; 95% CI, 0.63-0.88; P for trend = .001; absolute risk reduction, 0.6%; hazard ratio for a 5-point increase, 0.92; 95% CI, 0.88-0.96). also filed under organics/health

Brazilian Researchers Link Rise in Colon Cancer to Increase in Pesticide Use  (Beyond Pesticides, November 7, 2018)  'The researchers link the rise in the country's pesticide use since the turn of the century to significant increases in colon cancer, particularly in the country's most intensive agricultural southern regions...Researchers note that as Brazil's agriculture industry has grown over the last two decades, it has become the world's leading consumer of pesticides. In the year 2000, roughly 160 million tons of pesticides were used in the country. By 2012, that number reached nearly 500 million tons. Scientists compared pesticides sold to standard mortality rates (SMR) in each Brazilian state. SMR measures mortality by comparing observed mortality to expected mortality when adjusting for age and gender. A rate above one indicates that there is excessive mortality. Despite improvements in detection and treatment, colon cancer deaths recorded in the country increased from roughly 950k in 2000 to over one million by 2012. Using a series of statistical models, researchers showed that as the amount of pesticide sold in the country increased, the SMR for colon cancer increased in close correlation. This trend held for both male and female populations.'

EWG is rethinking cancer prevention (April 2016) Traditional initiatives that aim to prevent cancer have largely ignored the role of toxic substances in the environment. EWG wants to change that with new investigations on environmental causes of cancer. We will inform and empower you with tips and tools to help stop cancer before it starts.

Agricultural Crop Density Linked to Childhood Cancer in Midwest (Beyond Pesticides, October 16, 2015) According to a new study, living in crop-dense regions is linked to increased leukemia and central nervous system cancers in children. Although there is a litany of scientific literature that highlights the link between pesticide exposure and childhood illness, this study is one of few that examines the relationship between residential exposures to agricultural pesticides via crop density and adverse health outcomes, and may serve as a basis for further investigation into childhood cancer rates in areas where agricultural pesticides are highly used. The study, titled Agricultural crop density and the risk of childhood cancer in the Midwestern United States: an ecologic study, was published in the journal Environmental Health.

President’s Cancer Panel Says Burden of Environmentally Induced Cancer Greatly Underestimated  (Beyond Pesticides, May 11, 2010. Posted in Agriculture, Cancer, Chemicals, Disease/Health Effects, Farmworkers)The Panel’s report: Reducing Environmental Cancer Risk: What We Can Do Now. "Part Two of the report focuses on sources and types of environmental contaminants, and its second chapter focuses specifically on agricultural sources of exposure... Approximately 40 chemicals classified by the International Agency for Research on Cancer (IARC) as known, probable, or possible human carcinogens, are used in EPA-registered pesticides now on the market.” The Panel notes that the pesticide tolerances, the allowable limit on food, have been criticized by environmentalists as being inadequate and unduly influenced by industry." " In addition, the report finds that health care providers often fail to consider occupational and environmental factors when diagnosing patient illness."

SK Residents support pesticide bylaws. ‘Nearly 7 out of 10 Saskatchewan residents (69%) believe that pesticides pose a threat totheir health and would support a law phasing out pesticides used to beautify lawns and gardens.’ says a Canadian Cancer Society-SK (CCS-SK) sponsored Ipsos Reid poll. CCS-Sk report on environmental carcinogens in Saskatchewan deals specifically with tobacco, second hand smoke, cosmetic use of pesticides and community right to know, and product labeling. (2008)
