Professor Janet Gray | Nancy Buermeyer – Public Health Advocacy in the Fight Against Breast Cancer

Sep 12, 2020 | Health and Medicine

Health advocacy is an often-overlooked part of the work of public health specialists, but in many ways, it can be argued to have the greatest long-term impact on the population’s health. Here we look at the impressive work of Professor Janet Gray (Vassar College) and Public Policy Strategist Ms Nancy Buermeyer, working with colleagues at Breast Cancer Prevention Partners, the leading USA science-based policy and advocacy organisation to focus on preventing breast cancer by eliminating exposure to toxic chemicals and radiation linked to the disease.

Public Health Advocacy and Disease Prevention

The discipline of public health is focussed on population health and has social justice at its heart: working to address the fundamental determinants of poor health through reducing health, social and economic inequalities; improving access to healthcare and healthy environments; and encouraging everyone from individuals to governments to ‘do the right thing’ to ensure people have health and well-being as fundamental rights.

The role of public health advocacy is, therefore, to be a proponent for vital health issues, new research, or to highlight risks to health, often as part of a political or legislative process. However, it may also be educating the public about community, social or environmental factors that may compromise health-related conditions, and working to mitigate those factors.

Public health advocates are skilled in utilising and communicating about complex health and research information, alongside knowledge of policy procedures to shape future legislative and regulatory approaches. As such, public health advocacy has delivered some of the largest stepwise improvements in the public’s health in the past 150 years, including the introduction of urban sanitation (started in London to reduce cholera in the mid-19th century), workplace health and safety legislation, and the banning of smoking in public places in the 1990s. These are all good examples that have changed established social norms and values, and significantly prevented illness and death.

Breast Cancer Prevention Partners (BCPP)

Professor Janet Gray (Vassar College) is a scientific advisor for and Senior Policy Strategist Ms Nancy Buermeyer works for Breast Cancer Prevention Partners (BCPP). Founded in 1992, BCPP is the USA’s leading science-based non-profit organisation dedicated to the prevention of breast cancer by working to eliminate our exposures to toxic chemicals and radiation. In its health advocacy model, BCPP works to educate the public about links between environmental toxicants, many of which are found in common products used daily, and risk for developing breast cancer. It also engages in both market-based and policy initiatives aimed at eliminating exposures to harmful chemicals.

In the USA, breast cancer incidence has risen by 40% since the 1970s and affects one in eight women during their lifetimes. The rise cannot be explained by genetic factors alone, and therefore BCPP’s mission is to raise awareness of, and take action to reduce exposure to, the many environmental factors, specifically toxic chemicals and radiation, that are contributing to breast cancer. Here we explore some of the contributions by Professor Gray and Ms Buermeyer to the scientific understanding of these issues and BCPP’s advocacy work, including its ground-breaking breast cancer prevention policy agenda.

State of the Evidence

Professor Gray is a leading academic figure in breast cancer prevention, compiling the scientific evidence that provides the foundation for advocacy for progressive chemical policy reform to address chemical exposures to carcinogens and other toxicants in consumer products and our living and working environments.

Working with BCPP colleagues, Professor Gray led the team that published the latest version of the BCPP’s State of the Evidence 2017: an update on the connection between breast cancer and the environment’. The regularly updated review is a centrepiece of BCPP’s work to raise awareness of their agenda and examines the continually growing and compelling scientific evidence linking radiation and chemical exposures to the increase in breast cancer incidence. The findings are both impressive and alarming.

The evidence cited leads to the inescapable conclusion that many common, everyday products and their by-products contain toxicants that can increase the risk of breast cancer. The report focuses on seven major areas of concern for BCPP: 1) hormones in pharmaceutical agents and personal care products; 2) endocrine disrupting compounds (EDC); 3) hormones in food (natural and additives); 4) non-EDC industrial chemicals; 5) tobacco smoking (active and passive); 6) shift work (light-at-night and melatonin); and 7) radiation.

There is a particular focus on reducing exposures from gestation through to early adulthood, as exposure-induced changes in genetic, epigenetic (relating to non-genetic influences on gene expression) and physiological processes in the developing mammary system can lead to a greater risk of developing breast cancer in later life.

Advocacy in Action and Policy Successes

As a Senior Policy Strategist at BCPP, Ms Buermeyer plays a major role in developing and implementing the public health policy and advocacy programmes for the organisation. This begins with utilising the evidence produced from the research described previously, to educate and inform the public and policymakers of the realities of breast cancer risks.

The comprehensive BCPP website ( is a fantastic resource for information and guidance to support anyone interested in the subject (whether professionals, policymakers or members of the general public), to understand the issues and to be empowered to ‘take action’ for change. Accurate knowledge, when in the public arena, can be a powerful tool to change public opinion, to put pressure on policymakers and to counter the misinformation and misleading claims of those with a vested interested in maintaining the status quo.

An excellent example of advocacy in practice is the 2018 BCPP report Right to know: exposing toxic fragrance chemicals in beauty, personal care and cleaning products’. In this report, BCPP set out to expose the hidden toxic chemicals in products in daily use, a situation enabled by the lack of USA consumer-protection legislation requiring the labelling of ingredients for cleaning products or fragrance in personal care products and reliance on ‘self-regulation’ by the manufacturers.

The testing of well-known products, especially those marketed at vulnerable populations (e.g., women of colour, children), endorsed by celebrities or marketed as ‘good for the environment’ or ‘green’ products, were featured to capture the greatest attention. A ‘top 10’ list of named commercial products, ranked as the most hazardous (defined as containing ‘the highest number of chemicals linked to cancer, hormone disruption, developmental and reproductive toxicity and respiratory effects’) was topped by a children’s shampoo marketed to children of colour, and included products endorsed by celebrities Taylor Swift and Jenifer Lopez, and designer Marc Jacobs. The report highlights the weak USA Food and Drug Administration laws and oversight that leave consumers largely unprotected.

For the companies exposed, the report and subsequent widespread news coverage were highly embarrassing and damaging to their reputation, undermining the carefully crafted deceits of their products being ‘gentle’, ‘natural’ and ‘sustainable’, for example. This information, leading to public awareness and action, can ultimately lead companies to reformulate their products to remove toxic ingredients.

In addition to press coverage, evidence from this report was important for the passage of the California Cleaning Product Right to Know Act, a bill that was shepherded through the California legislature by BCPP, in partnership with its allies. This is currently the only law in the world that requires manufacturers of cleaning products to disclose the chemicals in their products, on product websites this year and on the product packaging by next year. In an example of ongoing work at the governmental level, in June 2020, BCPP and co-sponsors Black Women for Wellness, CALPIRG and the Environmental Working Group were successful in lobbying the California State Assembly to approve the historic ‘Toxic-Free Cosmetics Act’ to ban a dozen highly toxic chemicals which are already banned in the EU, from personal care products sold in the state. If approved by the state senate, it will be the first such law passed in the USA.

Moving Forward: Combining Science, Community Wisdom and Advocacy

Over the past 4 years, Ms Buermeyer led the BCPP team in developing the ground-breaking ‘Paths to Prevention: the California Breast Cancer Primary Prevention Plan’, which was launched in September 2020. With input from academics, government regulators, non-profit organisations and impacted communities, Ms Buermeyer describes the ‘first of its kind’ report as, ‘a labour of love that combined science and community wisdom to identify 23 factors impacting breast cancer risk and provide recommendations on research to better understand them and, most importantly, policy interventions to reduce breast cancer risk in California.’

Paths to Prevention is unique in several ways:

  • Focuses exclusively on primary prevention – stopping the disease before it starts.
  • Calls for systemic solutions to decrease breast cancer risk factors rather than focusing on individual actions.
  • Weaves together the wisdom of local communities and scientific evidence.
  • Considers these issues and their potential solutions through a social justice lens to ensure everyone benefits from policy change.

A key element of developing the Prevention Plan involved BCPP staff travelling across the state to meet with members of marginalised, environmental justice communities who bear a disproportionate burden of toxic exposures. The wisdom and learnings from these community meetings are deeply embedded in the Prevention Plan.

The Paths to Prevention will provide a blueprint for BCPP’s work going forward. While focused on the state of California, the Prevention Plan will hopefully become a model for states across the USA. While focused on breast cancer prevention, the recommended policy interventions will reduce the risk of numerous other health issues. This is fantastic evidence that the work of public health advocates such as Professor Gray and Ms Buermeyer is bringing about meaningful population-level changes to reduce the unnecessary deaths and illness caused by breast cancer.

Dr Hiroaki Nishiyama – A New Solution for Direct Laser Writing

Direct Laser Writing is a remarkably useful way to deposit intricately patterned materials onto surfaces. So far, however, the range of materials that can be used in the technique has been severely restricted. Now, Dr Hiroaki Nishiyama and his team at Yamagata University in Japan introduce an entirely new approach based on the unique properties of nanoparticles when suspended in a silver-based solution. When illuminated with ultra-short laser pulses, the setup can create highly stable patterns with sophisticated nanoscale structures – substantially broadening the range of materials available for use in the technique.

The Wasting and Stunting Technical Interest Group: Generating Evidence to Challenge the Divide in Nutrition

Despite improvements in children’s nutrition over the past few decades, undernutrition remains a huge threat to the health and life of infants and young children worldwide. Health and nutrition actors have usually approached the problems of children being wasted, (thinner than they should be) and children who are stunted (shorter than they should be) as different outcomes of undernutrition with different causes and different interventions. Facilitated by the Emergency Nutrition Network (ENN), since 2014 the Wasting and Stunting Technical Interest Group (WaSt TIG) has challenged this view, and has begun to work to provide evidence for a unified approach to tackling these two outcomes of undernutrition.
