The onus is on the ill: Environmental contaminants and hormonal health issues

The author contends that health issues such as endometriosis, PCOS, and breast cancer are linked to endocrine disrupting chemicals (EDCs) and xenoestrogens found in plastics, pesticides, and cosmetics. The text criticizes a medical and social narrative that places the onus of prevention on individual lifestyle choices, arguing instead that corporate profit and inadequate regulation drive exposure. It calls for healthcare professionals to acknowledge these environmental links and urges support for strengthening the Canadian Environmental Protection Act (CEPA) via Bill S-5.

• Endocrine disrupting chemicals (EDCs), xenoestrogens, parabens, pesticides, and plastics can cause significant human health impacts by mimicking estrogen and antagonizing estrogen receptors, affecting metabolic, epigenetic, growth, and reproductive processes.
• Exposure to EDCs is nearly universal due to their presence in air, food, water, and commercially available plastic products; blood samples from 2005 showed EDCs in 100% of tests, and 2022 research provided the first evidence of microplastics in human blood.
• The document identifies a conflict of interest where biotech and pharmaceutical companies profit from both the manufacture of carcinogenic chemicals and the subsequent medical treatments for the diseases those chemicals cause.
• Sociological and political structures, including consumerism, planned obsolescence, and regulatory gaps, exacerbate chemical exposure, while health issues affecting women and AFAB individuals are often dismissed or under-treated.
• The author advocates for collective action to push Canada to stop the circulation of harmful chemicals and specifically supports the strengthening of Bill S-5 to modernize the Canadian Environmental Protection Act (CEPA).
