A recent study from researchers at the American University in Cairo presents alarming data suggesting that rising global temperatures are correlated with increasing rates of certain cancers in women. The research highlights a troubling trend: for every one degree Celsius increase in temperature, the incidence of breast, cervical, ovarian, and uterine cancers has risen by as much as 280 cases per 100,000 women across 17 Middle Eastern and North African countries over the past two decades. This increase in cancer incidence, particularly pronounced for ovarian cancer, is complemented by an average rise in related deaths ranging from 171 to 332 per 100,000 for each degree of warming.

This study, published in the journal Frontiers in Public Health, underscores a broader public health crisis, linking climate change not only to physical health challenges but also suggesting that environmental factors could exacerbate the prevalence of cancers in vulnerable populations. According to Dr. Wafa Abuelkheir Mataria, the lead researcher, the findings indicate a cumulative public health impact that demands urgent attention. Although the study did not establish direct causation, the researchers suggest potential explanations, including increased exposure to carcinogens released during extreme weather events like wildfires, which are becoming more frequent due to climate change.

The implications of this study extend beyond the Middle Eastern context, with parallels observed in the United States and the United Kingdom, where cancer rates among women have also escalated. In the U.S., for example, breast cancer diagnoses have increased by about one per cent annually since 2012. Similarly, uterine cancer prevalence has also shown a steady rise, affecting tens of thousands of women each year. The World Health Organisation estimates that breast cancer deaths in the UK could surpass 17,000 by 2050 unless significant interventions are made.

Furthermore, severe disparities exist in access to healthcare, particularly for marginalized groups, leading to higher risks of late diagnoses and poor outcomes. Dr. Sungsoo Chun, a co-author of the study, emphasised that women are particularly vulnerable to climate-related health risks during physiologically sensitive times, such as pregnancy and menopause. The study calls for amplified focus on screening programs and preventative measures, particularly in regions susceptible to climate change effects, as ongoing neglect could worsen these health outcomes.

The current political landscape is also influencing the fight against climate change. The Trump administration has been publicly sceptical of climate science, dismantling previously established regulations aimed at mitigating environmental impact and potentially heightening the public health crisis related to cancer. For instance, a proposal from the U.S. Environmental Protection Agency seeks to roll back regulations on greenhouse gas emissions from fossil fuel power plants, contradicting empirical evidence linking fossil fuels to global warming and its health effects.

Despite the controversial decisions made in the previous administration, many experts hold out hope for advancements in public health informed by careful research and data. As the need for robust climate policies grows ever more critical, the intersection of climate change and health continues to gather urgent attention. The evidence presented by the Cairo study adds to a rising chorus of calls for a comprehensive approach that not only addresses climate change but also prioritises the health of populations disproportionately impacted by its consequences.

In light of these findings, it becomes crucial to acknowledge the potential long-term health ramifications of climate change. Without proactive measures to address both environmental and public health crises, the risk of increased cancer rates could persist, aggravating existing inequalities and threatening the well-being of countless individuals.
