Are everyday products from cosmetics to household cleaners causing the high rates of breast cancer?

‘No Family History’ author makes compelling case for environmental link to breast cancer and urges women, advocates, and policymakers to focus on prevention.   

Chemicals in your Bathroom can cause CancerPHILADELPHIA – Has the key to reducing breast cancer gotten lost in the race for a cure? A new book, No Family History, presents compelling evidence that exposure to everyday products such as cosmetics and toiletries, hormones in food, household cleaners and pesticides is behind the dramatic increase in breast cancer and argues that the solution is simple: prevention.  

“Every three minutes, one woman in the United States is diagnosed with breast cancer. Yet, most women with breast cancer defy most or all of the risk factors, including weight, diet, whether they gave birth and breast fed, and family history,” says No Family History author Sabrina McCormick, Ph.D., a Robert Wood Johnson Foundation Health & Society Scholar at the University of Pennsylvania. 

The incidence of breast cancer has increased at an alarming rate over the past 60 years. In 1940, around one in 24 women who lived to be 80 was afflicted. By 2006, that number rose to one in eight.  

In her book, McCormick cites compelling evidence showing that the reason for this dramatic increase is the rise in the production and use of cancer-causing chemicals women are exposed to on a daily basis.  

Breast cancer “hot spots” from Long Island, N.Y., to Northern California have two common threads—industrial pollution and agricultural pesticides. These “hot spots” are pockets of the United States where breast cancer has risen six times faster than the national rate. In Long Island, the incidence of breast cancer is 200 percent higher than the national average. 

“In our race for a cure for breast cancer, we have ignored the overwhelming body of evidence that demonstrates a link between products from cosmetics to pesticides and breast cancer,” McCormick says. “We must focus on prevention by demanding safer products, reducing our exposure to chemicals and urging our policymakers to ban cancer-causing chemicals in everyday products.” 

European governments responded to this scientific evidence by banning cosmetic products with certain chemicals from being sold in their countries. According to No Family History, one American cosmetics company known as much for its “pink ribbon” marketing campaigns as for its pink lipstick removed these chemicals from products sold in Europe, but these same chemicals remain in the products the company sells in the United States. 

“Women and girls should not have to check the ingredients in every stick of lipstick and each bottle of moisturizer. Better regulation to ensure that these products are safe would go a long way to reducing the incidence of breast cancer,” McCormick says. 

Many companies that profit from “pink” marketing campaigns or breast cancer treatments, McCormick argues, are the same ones fighting against tougher regulations of cancer-causing chemicals in everyday products. McCormick dubs this the “political economy” of breast cancer.

“In the case of breast cancer, many activists have unwittingly bought into campaigns leading down the road away from a cause, and instead into more and more breast cancer,” McCormick writes in her book. 

No Family History: The Environmental Links to Breast Cancer (Rowman & Littlefield) is a provocative glimpse into environmental links to breast cancer, profiling research as well as women’s stories. McCormick recommends that women reduce their exposure to many cosmetics and toiletries and urges policymakers to strengthen regulations to ban cancer-causing chemicals from being used in everyday products.

Reducing the incidence of acute pesticide poisoning by educating farmers on integrated pest management

farmer in India

Sixty-five farmers reported on pesticide use and the signs and symptoms of acute pesticide poisoning when using two different plant protection strategies: in 2003 using chemical controls and in 2004 using an approach to Integrated Pest Management (IPM) based on an ecological analysis of the field conditions.

Exposure to organophosphates was confirmed as a serious risk factor for occupational poisoning. The adoption of IPM reduced the use of pesticides and halved the incidence of acute pesticide poisoning. Overall, the pesticide use spectrum shifted towards lower WHO Hazard Classes. A reduction of adverse health effects was attained through a reduction in exposure to toxic pesticides and behavioural changes. Given that other strategies to reduce the rate of acute poisoning have proven ineffective, interventions aiming to minimize pesticide poisoning in India and in other developing countries with similar rural conditions should focus on restricting the use of highly toxic compounds and educating farmers on IPM.

Global air monitoring study: a multi-country comparison of levels of indoor air pollution in different workplaces

Smoking causes Indoor Air Pollution

A local study completed in Singapore, which was part of an international multi-country study that aims to develop a global assessment of exposure to second-hand smoke in indoor workplaces, gathered data regarding the indoor air quality of public areas. It was hypothesised that air would be less polluted in non-smoking venues compared to places where smoking occurred.  

A TSI SidePak AM510 Personal Aerosol Monitor was used to sample and record the levels of respirable suspended particles (RSP) in the air. A broad range of venues were sampled in Singapore. The primary goal of data analysis was to assess the difference in the average levels of RSP in smoke-free and non smoke-free venues. Data was assessed at 3 levels: (a) the mean RSP across all venues sampled compared with the mean levels of smoke-free and non smoke-free venues, (b) levels in venues where smoking occurred compared with similar venues in Ireland, and (c) comparison between smoke-free and non smoke-free areas according to the type of venue. Statistical significance was assessed using the Mann-Whitney U-test.

The level of indoor air pollution was 96% lower in smoke-free venues compared to non smoke-free venues. Averaged across each type of venue, the lowest levels of indoor air pollution were found in restaurants (17 microg/m3) and the highest in bars (622 microg/m3); both well above the US EPA Air Quality Index hazardous level of >or=251 ug/m3.  

This study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public areas dramatically reduce exposure and improve worker and patron health.
