Petrochemicals, a ubiquitous part of modern life, are increasingly being recognized as a major contributor to cancer risks and a significant threat to overall health.

A commentary published in JAMA Oncology sheds light on the intricate pathway of petrochemical processing and its profound negative impact on human well-being.

This article explores the various stages of petrochemical processing and their associated health risks.

The Petrochemical Processing Pathway

Petrochemicals follow a comprehensive processing pathway, encompassing multiple stages from extraction to disposal.

Each step along this pathway poses additional health risks, creating a cumulative impact on individuals and communities.

Petrochemical production infrastructure is densely interconnected, resulting in more widespread human exposures.

The authors cite “Cancer Alley” in Louisiana, an area with over 200 petrochemical facilities and cancer rates up to 50 times the national average, as an alarming example.

They emphasize that marginalized communities are often disproportionately affected due to discriminatory policies, systemic racism, and limited political power.

Petrochemicals are in constant motion, transported via pipelines, trucks, trains, and ships.

This mobility places a wide range of communities at potential risk, extending the reach of petrochemical hazards beyond industrial centers.

The authors highlight the case of East Palestine, Ohio, where a freight train derailment exposed the community to vinyl chloride, a known carcinogen.

This incident underscores the pervasive nature of petrochemical risks, affecting even non-industrial and non-marginalized areas.

Petrochemicals and Climate Change

Petrochemical processing is inherently emission-intensive, releasing substantial amounts of greenhouse gases. This contribution exacerbates climate change, posing a grave threat to human health.

Climate change-related disasters, such as extreme heat, wildfires, hurricanes, and floods, disproportionately affect cancer patients, disrupting their healthcare and increasing their vulnerability.

The Healthcare Industry’s Role

The healthcare sector is a significant consumer of petrochemical products, particularly single-use plastics, and accounts for 8.5% of greenhouse gas emissions.

Paradoxically, the industry that strives to save lives inadvertently contributes to environmental problems.

The authors call for greater awareness within the healthcare sector and urge clinicians to replace disposable and single-use items with reusable alternatives whenever feasible.

Reducing reliance on plastics and disposables not only mitigates the environmental impact of the healthcare industry but also enhances supply chain resilience during disasters.

By adopting eco-friendly practices, healthcare providers can contribute to a healthier planet and reduce community exposure to hazardous substances.


Understanding the hidden pathway of petrochemical processing and its association with cancer risks is paramount for safeguarding public health.

By acknowledging the interconnectedness of petrochemical infrastructure, promoting environmental responsibility within the healthcare industry, and adopting sustainable practices, we can mitigate the detrimental impact of petrochemicals on our health and the environment.
