Global warming could feed the growing cancer rates in women, a shock study suggests.
Researchers in Egypt analyzed the speeds of breast, cervical, ovar and uterine canches in 17 countries in the middle and compared to rising temperatures over time.
They discovered that for each degree Celsius (1.8 degrees Fahrenheit) temperatures increased, cases of the four cancers on average to 280 per 100,000 people in the last 20 years.
Increased total cases were most common with ovarian cancer, with an increase of 280 per 100,000 people, and the least common in breast cancer, with an increase of 173 per 100,000.
The deaths of all four cancers also rose on average with 171 to 332 deaths per 100,000 for each degree of temperature rise. The largest rise in the dead was in ovarian cancer with 332 per 100,000, and the smallest was in cervical cancer at 171 per 100,000.
The experts of American University in Cairo note that their study was observational and proves no causal connection. But they believe that global warming could increase to the exposure to carcinogens, as created by natural fire pollution.
Extreme weather conditions such as forest fires and hurricanes can also disrupt the required screening and cancer treatments, which causes an increase in cases and deaths.
Women are also considered more susceptible to these health effects of climate change, especially during pregnancy and menopause.
A new study in Borders in Public Health showed that the percentages of four common women’s cancer, including breast cancer, have risen as the temperature rose. Shown above is a stock image of a woman who gets a mammogram to test on breast cancer

Dr. Wafa Abuelheir Mataria, first study -author and researcher at American University in Cairo, said: ‘As the temperatures rise, the mortality of cancer in women increases – especially for ovary and breast cancer.
“Although the rises per temperature rise are modest, their cumulative impact of public health is considerable.”
Although the research only looked at countries in the East and North Africa, the US and the UK have also been hit by climate change and rising rates of some female cancers.
Breast cancer, who touches 330,000 American women every year, has risen one percent every year since 2012, according to the American Cancer Society, according to the American Cancer Society.
The womb or endometrial cancer rates have also risen by around 0.6 percent per year from 2010 to 2019. The disease affects 69,000 American women and kills 14,000 every year.
However, ovary and cervical cancers have fallen by a maximum of two percent per year over the past decade, largely due to an increased use of contraception and better access to the vaccine of the Human Papillomavirus (HPV).
In the UKOne woman is diagnosed with breast cancer every 10 minutes and adds up to 55,000 a year.
More than 12,000 women lost their lives to breast cancer at the disease in 2022, and figures show that it will affect more than 17,000 in half a century, the World Health Organization (WHO) said.
Ovarian cancer affects 7,500 women in the UK and kills 4,300, and uterine cancer affects 10,000 and kills 2,500. And every year 3,300 British are hit by cervical cancer and 850 lose their lives.
The findings also come after President Donald Trump had accepted 1,000 climate scientists from the Environmental Protection Agency (EPA) after a history of rejecting climate change as a hoax.
The study, published on Tuesday in the magazine Frontiers in Public HealthCollected data on cases and deaths due to breast, cervical, ovar and uterine cancer for 17 countries in the East and North Africa.
Nations included in the study were Algeria, Bahrain, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Saudi -Aarabia, Syria, Tunisia, United Arab Emirates and Palestine.
The team then compared kank data with changing temperatures in each country. All data collected, from online databases from the United Nations, represented 1998 to 2019.

Symptoms of breast cancer to pay attention are nodules and swellings, hole of the skin, changes in color, discharge and a rash or crust around the nipple
For each degree Celsius of temperature change, the cases of the four cancers increased by between 173 and 280 extra cancers per 100,000 people.
Ovarian cancer had the largest increase in 280 extra cancers, while the chest had the smallest at 173.
The deaths of cancer generally increased by 171 to 332 deaths per 100,000 for each degree of temperature rise. The biggest increase in the dead was in ovarian cancer and the smallest was in cervical cancer.
The prevalence of cancer and deaths rose alongside the temperatures in six countries: Qatar, Bahrain, Jordan, Saudi -Aarabia, the United Arab Emirates and Syria.
Breast cancer increased by 330 cases per 100,000 people in Bahrain, 560 in Qatar and 440 in the VAE. In summary, breast cancer rose 420 per 100,000 in Jordan, 550 per 100,000 in Qatar, 310 per 100,000 in Saudi Arabia and 350 per 100,000 in the VAE for every degree of Celsius.
The prevalence of ovarian cancer increased in Bahrain, Jordan, Qatar, Saudi Aarabia and the VAE with 390, 460, 540 and 290 per 100,000 people respectively, as the temperature rose.
The deaths due to ovarian cancer in those four countries rose between 330 and 480 per 100,000.
Cervical cancer increased in Bahrain, Qatar and Syria with 380, 510 and 250 cases per 100,000 respectively. The deaths due to the disease increased by 330 per 100,000 in Iran, 450 per 100,000 in Jordan and 610 per 100,000 in Qatar.
For uterine cancer, the prevalence increased in Jordan, Qatar, Saudi Aarabia and the VAE with 480 per 100,000, 620 per 100,000, 360 per 100,000 and 370 per 100,000, respectively.
Deaths due to uterine cancer rose in Jordan and Qatar with 440 and 430 per 100,000.
Dr. Sungsoo Chun, co-author and associated chairman of the Institute of Global Health and Human Ecology at American University in Cairo, said: ‘Temperature rise probably works via multiple paths. It increases exposure to well -known carcinogens, disrupts the delivery of health care and can even influence biological processes at a cellular level.
“Together these mechanisms can increase the risk of cancer over time.”
He also noted that women are more physiologically vulnerable to climate -related health risks, especially during pregnancy. ‘
‘This is exacerbated by inequalities that limit access to healthcare. Marginalized women are confronted with a multiplied risk because they are more exposed to environmental hazards and are less able to gain access to early screening and treatment services, “he added.
Dr. Mataria warned the study ‘cannot determine direct causality’ and there may be other factors in individual countries that influence the cancer rates in women.
She said, “Nevertheless, the consistent associations that have been observed in several countries and cancer types offer for further research.”
The team called for stronger cancer screening programs in areas that are particularly susceptible to climate change, as well as reducing exposure to environmental arcinogens.
Dr. Chun said, “Without tackling these underlying vulnerabilities, the Cancer Krief that is linked to climate change will continue to grow.”
