Prenatal DDT exposure linked to increased risk of breast cancer

Though the chemical is now banned from use in the US and many other countries due to health concerns, a new study finds women who were exposed to higher levels of the chemical in utero more than 50 years ago may be at almost fourfold increased risk of breast cancer than women exposed to lower levels. DDT was a commonly used pesticide in the 1960s, but its use was banned in the US in 1972 due to health concerns. According to Cohn, there has long been suspicion that exposure to environmental chemicals such as DDT may be also linked to breast cancer. As such, she and her colleagues assessed the risk of breast cancer among 9,300 women in the US born between 1959 and 1967 - a period when DDT use was common in the country.[5]

Pregnancy Complications Increase Long-Term Risk of Cardiovascular Death

Several pregnancy complications increase the long-term risk of death from cardiovascular disease, according to results from the Child Health and Development Studies . "Results suggest the need for prompt intervention in women with these pregnancy complications, even for young women of reproductive age," Dr. Barbara A. Cohn, director of CHDS at Public Health Institute, Berkeley, California, told Reuters Health by email. Previous research has linked various complications of pregnancy with subsequent cardiovascular disease risk, but few studies have investigated the combination of pregnancy complications that confer high risk. Dr. Cohn and Piera M. Cirillo used data from CHDS to examine the relationship of the co-occurrence of multiple pregnancy complications to cardiovascular disease risk over five decades.[4]
