DDT and Breast Cancer in Young Women: New Data on the Significance of Age at Exposure 07/07 Environmental Health Perspectives (Scientific Paper)
Stored blood samples taken from women enrolled in Child Health and Development Studies, Oakland, California between 1959 and 1967 were analysed for traces of DDT. High levels of serum DDT predicted a statistically significant five-fold increased risk of breast cancer among women who were born after 1931. These women were under age 14 in 1945, when DDT came into widespread use and mostly under age 20 as DDT use peaked. Women who were not exposed to DDT before age 14 showed no association between DDT and breast cancer. This shows that exposure to p,p’-DDT early in life may increase breast cancer risk.
Increased Risk of Relapse After Breast Cancer With Exposure to Organochlorine Pollutants 02/07 Bulletin of Environmental Contamination and Toxicology (Scientific Paper)
125 breast cancer patients who had previously been treated using surgery and chemotherapy had their blood sampled and the concentration of chlorinated pesticide residues measured. When the results were adjusted for age, patients who had suffered relapses were found to have higher residue concentrations than those who had not.

A case-controlled study involving over 1500 newly-diagnosed breast cancer patients concluded that residential pesticide use to control lawn and garden pests increases the risk of breast cancer.
Scientists link plastic food containers with breast cancer 03/07 The Guardian (News article)
The offspring of mice exposed during late pregnancy to doses of Bisphenol A equivalent to the estimated exposure of humans using plastic food containers developed breast tissue that was far more susceptible to breast cancer than that of unexposed mice. The breast tissue had more terminal end buds, the tissue most susceptible to tumour development, and fewer of these cells were programmed to undergo cell death, one of the most effective natural mechanisms used by the body to combat cancer. The breast tissue of exposed mice was also more sensitive to oestrogen than normal, which also increased their susceptability to breast cancer.
Bisphenol A Induces Breast Cancer in Rats 12/06, Reproductive Toxicology (Scientific Paper)
Bisphenol A, a chemical widely used in plastics and epoxy resins, has been found to promote the development of breast cancer in rats exposed to the chemical as foetuses. The effect is seen at doses as low as 2.5ìg/kg bodyweight.
The Geography of Breast Cancer 10/06 Ms Magazine (News Article)
Why do women living in Cape Cod have a rate of breast cancer 20% higher than those in the rest of Massachusetts? Reporter Francesca Lyman joins two-time breast cancer survivor Jane Chase and others in her community as they work to unravel the toxic secrets of their neighbourhood.
"Gender Bending" Chemicals Linked to Breast Cancer Rise 10/06 The Telegraph (News Article)
A study conducted by the World Wildlife Fund (WWF) has found a link between the exposure of girls to endocrine disrupting compounds at cruicial stages in their development and breast cancer later than life. During foetal development and at puberty they are at most risk, and the compounds present in the environment can work synergistically with each other, causing a greater effect than would be anticipated if the compounds acted independantly. Tighter legislative control of endocrine disrupting compounds was called for.
