May 27, 2025 — A new study has found that rising temperatures in the Middle East and North Africa (MENA) are associated with an increase in both the prevalence and mortality of certain women’s cancers, including breast, ovarian, uterine, and cervical cancers. The research, published in Frontiers in Public Health, highlights the growing public health threat posed by climate change, particularly for women in vulnerable regions.
Key Findings
Researchers from the American University in Cairo analyzed data from 17 MENA countries between 1998 and 2019, focusing on the relationship between ambient temperature increases and cancer rates. The study found:
-
Cancer Prevalence: For every additional degree Celsius of temperature rise, the prevalence of these cancers increased by 173 to 280 cases per 100,000 people. Ovarian cancer saw the highest increase, while breast cancer saw the lowest.
-
Cancer Mortality: Mortality rates rose by 171 to 332 deaths per 100,000 people for each degree of temperature rise, with ovarian cancer again showing the largest increase.
-
Country Variations: The rise in cancer rates was most pronounced in six countries—Qatar, Bahrain, Jordan, Saudi Arabia, the United Arab Emirates, and Syria—possibly due to more extreme temperatures or other environmental factors.
Why Are Rates Rising?
The study suggests that higher temperatures may increase exposure to environmental carcinogens, disrupt healthcare delivery, and even influence cancer development at the cellular level. Additionally, women—especially those who are pregnant or marginalized—are more vulnerable due to both physiological factors and limited access to healthcare.
“Temperature rise likely acts through multiple pathways,” said Dr. Sungsoo Chun, co-author of the study. “It increases exposure to known carcinogens, disrupts health care delivery, and may even influence biological processes at the cellular level. Together, these mechanisms could elevate cancer risk over time.”
Implications for Public Health
The findings underscore the need for climate-resilient healthcare systems and improved cancer screening programs in the region. “Strengthening cancer screening programs, building climate-resilient health systems, and reducing exposure to environmental carcinogens are key steps,” Chun emphasized.
While the study controlled for economic factors, the authors caution that other unmeasured variables may also play a role. They stress that the research shows a strong association, but not direct causality, between rising temperatures and increased cancer rates.
Looking Ahead
This research adds to a growing body of evidence that climate change is not just an environmental issue, but a significant public health concern—especially for women in regions already facing healthcare challenges.
