Air Pollution Linked to Gynaecological Cancers, Experts Say

The Cliff News | 12 October 2026

Long-term exposure to air pollution, particularly fine particulate matter (PM2.5), may contribute to the development of gynaecological cancers, according to leading experts in the Delhi-NCR region. This emerging scientific understanding points to potential links between chronic exposure to airborne pollutants, reproductive health, and cancers affecting the female reproductive system.

Gynaecological cancers are complex diseases with multiple contributing factors, and environmental influences are increasingly being recognized as potential contributors to the biological pathways involved in their onset. Experts are focusing on PM2.5 due to its known association with systemic inflammation and oxidative stress.

Emerging Research on Pollution and Reproductive Health

Dr. Rama Joshi, a renowned gynae onco surgeon and chairman at Fortis Gurugram, highlighted the growing interest in PM2.5. She explained that "prolonged exposure is associated with inflammation, oxidative stress and systemic biological effects." Recent studies have begun to explore connections between air pollution and various aspects of women's reproductive health, prompting questions about whether environmental factors could also influence the broader cancer risk landscape for women.

However, Dr. Joshi cautioned against drawing direct causal conclusions at this stage. She emphasized that an observed association between pollution exposure and cancer does not equate to direct causation. The evidence for gynaecological cancers is still in its early stages, and findings have varied across different research efforts. More data specific to the Indian population is needed to establish definitive links.

"Women should focus on the risk factors that we already know can be modified or monitored. Maintaining a healthy weight, staying physically active, managing diabetes and other metabolic conditions, understanding family history and seeking timely evaluation for abnormal bleeding remain important. Environmental pollution is an additional concern that deserves further scientific investigation," stated Dr. Joshi.

India-Specific Study Highlights Reproductive Health Impacts

Experts referenced a recent nationwide study that investigated the relationship between environmental exposure and reproductive health outcomes among Indian women. The findings indicated significant impacts on key reproductive milestones linked to PM2.5 levels.

The study revealed that women exposed to PM2.5 concentrations exceeding 40 micrograms per cubic metre faced a 24 per cent higher likelihood of delayed menarche (the onset of menstruation) and a 23 per cent increased hazard of early menopause. This analysis utilized data from the National Family Health Survey combined with satellite-derived PM2.5 estimates and other environmental indicators.

The research encompassed a substantial cohort, analyzing data from nearly 1.8 lakh women aged 15-24 for menarche and approximately 3 lakh women aged 30-49 for menopause. Notably, the associations were more pronounced in northern India, including regions such as Delhi, Haryana, Punjab, and parts of Uttar Pradesh.

Understanding Biological Mechanisms

These findings are fueling scientific curiosity into how prolonged exposure to air pollution might affect women's hormonal and reproductive pathways. Researchers are actively examining whether the biological effects linked to PM2.5, such as chronic inflammation, oxidative stress, and cellular damage, could potentially contribute to conditions affecting hormone-sensitive tissues and the female reproductive system.

The article also touched upon known risk factors for specific gynaecological cancers. For endometrial cancer, these include obesity, prolonged oestrogen exposure, diabetes, age, and certain genetic predispositions. Ovarian cancer has its own set of risk factors, including age, family history, and inherited genetic mutations.

Growing Concern in High-Pollution Areas

The possibility that chronic environmental exposure could exacerbate these established risk factors is an area of escalating scientific interest. Long-term exposure to fine particulate matter is believed to exert systemic effects beyond the respiratory system, potentially influencing inflammatory, hormonal, and cellular processes crucial to cancer biology.

This issue carries particular weight in areas like the Delhi-NCR, where women are repeatedly exposed to elevated PM2.5 concentrations over many years. The known links between fine particulate matter and systemic effects like inflammation and oxidative stress are prompting scientists to investigate whether these biological pathways could influence hormone-sensitive organs within the female reproductive system, thus contributing to cancer risk.
