Along with changing coastlines, crops and summer camp plans, climate change may wreak another form of havoc — on women’s health.
According to a study published in May in the journal Frontiers in Public Health, a warming world could also increase women’s rates of cancer. Along with increasing rates of occurrence, the study pointed to mortality increases, too.
Global warming could increase rates of cancer in women
The study focused on women’s health in 17 countries in the Middle East and North Africa — already-hot parts of the globe that have been getting even hotter. The findings were disturbing: breast, ovarian, uterine and cervical cancers all became both more common with each degree of temperature increase — and more fatal.
Using cancer prevalence and mortality data — as well as temperature changes — over the two decades between 1998 and 2019, the researchers found that the overall prevalence of these four cancers increased from 173 cases per 100,000 people to 280 cases for every additional degree Celsius. Mortality rates increased from 171 deaths per 100,000 people to 332 deaths at the same scale. These increases are small, but statistically significant, and are not explained by improved diagnostics or survival rates.
