We live surrounded by substances that, while unnoticed in our routine, may be affecting our health more than we realise. Environmental toxics - from chemicals in the air to residues in food - have been the subject of study for decades, and there is growing evidence of their link to cancer. But what are these toxins, how do they affect us, and what can we do about them? In this article we explore this link and why it deserves our attention.
What are environmental toxicants?
Environmental toxics are chemicals or physical agents present in our environment that can be harmful to our health. Some common examples include:
- Air pollutants: Such as benzene (in fuels) or particulate matter from diesel exhaust.
- Pesticides: Glyphosate or DDT residues on crops.
- Heavy metals: Lead, mercury or arsenic in contaminated water or soil.
- Industrial chemicals: Bisphenol A (BPA) in plastics or phthalates in everyday products.
- Radiation: Both natural (radon in soil) and man-made (excessive UV rays).
These elements are in the air we breathe, the water we drink, the food we eat and even the objects we touch. Although many are regulated, prolonged or combined exposure at low doses raises questions about their long-term impact.
How are they linked to cancer?
Cancer occurs when cells in our body begin to grow out of control, often due to mutations in DNA. Environmental toxins can act as triggers for these mutations in several ways:
- Direct DNA damage: Substances such as arsenic or dioxins can alter genetic material, increasing the risk of tumours.
- Chronic inflammation: Constant exposure to fine particles (such as asbestos) irritates tissues, creating an environment conducive to the development of cancer cells.
- Hormone disruption: Compounds such as BPA mimic hormones, which is linked to cancers such as breast and prostate cancer.
- Accumulation in the body: Some toxics, such as heavy metals, are stored in tissues and their effect is enhanced over time.
- Agencies such as the International Agency for Research on Cancer (IARC) classify many of these agents as ‘carcinogens’ (cancer-causing). For example, asbestos and benzene are confirmed carcinogens, while others, such as certain pesticides, are under suspicion and ongoing study.
Scientific evidence
Studies have found worrying links:
- Polluted air: Living near industrial areas or heavy traffic is associated with increased risk of lung cancer.
- Pesticides: Farmers exposed to glyphosate show higher rates of non-Hodgkin's lymphoma.
- Contaminated water: Arsenic in wells has been linked to skin, liver and bladder cancer in affected regions.
- Plastics: BPA and phthalates are being investigated for their possible role in hormone-dependent cancers.
A World Health Organisation (WHO) report estimates that between 7% and 19% of cancers may be linked to environmental factors, although these figures vary by region and level of exposure.
What can we do about it?
While we cannot eliminate all toxics from our environment, there are practical steps to reduce risks:
- Filter your water: Use filtration systems to remove heavy metals or chemicals.
- Choose organic food: Reduce exposure to pesticides by opting for organic products whenever possible.
- Ventilate spaces: Reduce the build-up of indoor pollutants such as radon or chemical vapours.
- Avoid toxic plastics: Prefer glass or stainless steel containers and check labels to avoid BPA.
Know your environment: Learn about air or water quality in your area and support environmental regulation policies.
Conclusion
The link between environmental toxics and cancer is not a conspiracy theory, but a sobering, science-backed reality. It is not about living in fear, but about making informed choices to protect ourselves. While not all cancers are preventable, reducing our exposure to these agents can be a key step towards a healthier life. The question is: what small changes are you willing to make today for your well-being tomorrow?
