Global Warming And Risk of Women’s Cancer
Global warming is transforming the world in various ways, and one of the unexpected impacts could be on the health of women. New studies indicate that global warming could be escalating the risk of cancer in women. The concept originates from studies investigating how global warming raises women’s risk of cancer through an analysis of heat, air pollution, and other environmental factors influencing the body.
Researchers caution that the warmer the planet becomes, the more women may be at increased cancer risk for cancers such as breast, ovarian, uterine, and cervical. This piece delves into the link between climate change and the risks to women’s health, what it indicates, why it occurs, and what it portends for the future.
Key Research on Climate Change and Cancer Rates
One of the most important studies released in May 2025 examined the effects of climate change on cancer rates among women in some detail. Scientists at the American University in Cairo studied information from 17 nations in the Middle East and North Africa, or MENA region. The regions are already hot and are projected to heat up by approximately 4 degrees Celsius by the year 2050.
Cancer risk and mortality among women from 2000 to 2020 were analyzed by the researchers, comparing it to temperature fluctuations. What they found was clear: as temperatures went up, so did the cancer risk in women. For every 1 degree Celsius increase, there were 173 to 280 more cancer cases and 171 to 332 more deaths per 100,000 women. Breast and ovarian cancers showed the strongest links to heat.
Insights from the Lead Author
The primary author, Wafa Abuelkheir, said that increased temperature appears to boost the risk of cancer in women, particularly for ovarian and breast cancers. This is not simply because medical records are kept better or because people are living longer. The trend persisted even when controlling for those variables. In countries such as Egypt, Saudi Arabia, and Iran, where heat waves have become increasingly frequent, the risk of cancer for women increased with the thermometer.

First, warmer temperatures result in more ultraviolet radiation from the sun. UV radiation can harm skin and other cells and increase the cancer risk. In hot climates, individuals spend more time indoors to escape the heat, but when outside, the strong sun can be damaging.
Second, global warming exacerbates air pollution. When fossil fuels are burned for energy, emissions of pollutants mix with the heat to produce smog. Such small particles can penetrate the body and initiate inflammation, possibly leading to cancer over the long term. Research indicates that air pollution is associated with gynecologic cancers, such as those of the ovaries or uterus, again demarcating the interface between climate change and women’s health dangers.
Hormonal Disruptions from Heat
Another issue concerns the way in which heat taxing the body operates. Temperature extremes can wreak havoc on hormones, chemicals that regulate many processes, such as cell growth. Women have special hormone systems related to reproduction, and heat may put them out of whack. As an example, temperatures far above normal can raise estrogen levels, a hormone associated with breast and ovarian cancer, raising the risk for cancer.
Toxins Released by Climate Change
Global warming also thaw ice and permafrost, liberating ancient poisons like pesticides into water and soil. These chemicals function similarly as endocrine disruptors, imitating hormones and possibly inducing cancerous cells to proliferate, adding to the effects of climate change on women’s cancer incidence.

Women may be more severely affected than men for several reasons. Physiologically, women’s bodies respond to heat in a different way. They perspire less effectively during severe weather, placing extra stress on organs, which may increase the cancer risk.
Social and Economic Factors
Social circumstances also have a role. Outdoors, women do more work such as farming or water fetching in most locations, subjecting them to heat and pollution. Inequality exacerbates: poor women frequently get little or no access to shade, fresh air, or medical care. In the MENA region, social norms may restrict women’s mobility but they still experience indoor heat from fire-cooking with added smoke pollution, further compounding the cancer risk among women.
Global Patterns and Evidence
This is not only an issue in warm nations. Earlier research in 2022 and 2023 indicates comparable trends across the globe. One review established that the link between climate change and the health hazards for women puts women’s cancers at greater risk through altering air quality, water purity, and food availability.

In the United States, states affected by wildfires and hurricanes record increased cancer risk for breast and lung cancers among women. Severe weather conditions, such as floods, can transfer cancer-inducing chemicals from farms or factories. While temperatures rise across the globe, such environmental influences contributing to cancer among women may reach cooler regions as well.
Solutions and Future Steps
The bad news is mitigated by the fact that awareness is increasing. Health professionals urge action to reduce emissions and slow down warming to eliminate the risk of cancer.
Governments can invest in improved cancer screening among vulnerable areas for women. Lowly measures such as tree planting for shade, air filter enhancement, and issuing heat alerts can reduce how global warming adds to women’s risk of cancer. Scientists call for more research on the effect of climate change on women’s cancer incidence so physicians can plan ahead.
Conclusion
Ultimately, global warming’s connection to women’s cancer risk indicates how interconnected human and planetary health is. If temperatures continue to rise, even more women might suffer from environmental causes instigating cancer in women. However, by addressing climate change now, societies can safeguard future generations. It’s a reminder that small actions today can avoid enormous issues tomorrow.
