Air pollution may increase breast cancer risk, study suggests
Long-term exposure to air pollution may increase the risk of breast cancer, with a study of more than 400,000 women showing higher rates in areas with poor air quality.
Researchers tracked 28,000 breast cancer cases over several decades, following participants for up to 10 years before diagnosis and monitoring changes in their home addresses.
They compared these data with pollution readings from more than 2,600 monitoring sites across the country.
The analysis was carried out by researchers from Oregon State University, the National Institutes of Health (NIH), Harvard University and several other US institutions.
A 10-parts-per-billion rise in nitrogen dioxide – a pollutant linked to vehicle exhaust – was associated with a 3 per cent increase in overall breast cancer incidence.
Based on an estimated 316,950 cases expected in the US this year, a 3 per cent reduction could mean 9,500 fewer diagnoses.
The study also found that a 5-microgram-per-cubic-metre increase in PM2.5 – fine airborne particles small enough to penetrate deep into the lungs – was linked to a higher incidence of hormone receptor-negative breast cancers.
These tumours lack oestrogen and progesterone receptors, making them generally harder to treat.
Average nitrogen dioxide levels in the study were below current Environmental Protection Agency guidelines, suggesting even legally acceptable pollution levels may still pose health risks.
Veronica Irvin is associate professor at Oregon State University’s College of Health.
She said: “It’s often not realistic for people to move to areas with better air quality in search of lower health risks, so we need stronger clean air laws to protect those most affected.
“We also need policies that help to reduce car traffic and promote alternative forms of transportation.”
Breast cancer rates in the US have risen over the past four decades, despite the country having lower pollution levels than many other populous nations.
The disease affects around one in eight women and is the second leading cause of cancer death among women after lung cancer.
There are currently more than 4 million breast cancer survivors living in the US.
The World Health Organization (WHO) has launched an AI tool in beta to help policymakers, experts and healthcare professionals access sexual and reproductive health information faster.
Called ChatHRP, the tool was created by WHO’s Human Reproduction Programme and draws only on verified research and guidance collected by HRP and WHO.
It uses natural language processing and retrieval-augmented generation to produce referenced content and cut the time spent searching through documents across different platforms and databases.
WHO said ChatHRP also has multilingual capabilities and low-bandwidth functionality to support use in a wide range of settings.
The beta-testing phase is aimed at a broad professional audience, including policymakers, healthcare workers, researchers and civil society groups.
WHO said the tool can help users quickly access up-to-date evidence, find sources for academic work and verify information on sexual and reproductive health and rights.
Examples of questions it can answer include the latest violence against women data in Oceania for women aged 15 to 49, recommendations on managing diabetes during pregnancy, and whether PrEP and contraception can be used at the same time. PrEP is medicine used to reduce the risk of getting HIV.
WHO added that the system will be updated regularly as new HRP materials are published and includes a feedback loop so users can flag gaps in the information provided.
The launch comes amid wider concern about misinformation in sexual and reproductive health.
A 2025 scoping review found that misinformation in digital spaces is a systemic issue that can undermine human rights, reinforce discriminatory social norms and exclude marginalised voices.
The review also said misinformation can affect health systems by shaping provider knowledge and practice, disrupting service delivery and creating barriers to equitable care.
WHO said ChatHRP is intended to give users streamlined access to reliable information as a counter to “algorithms, opinions, or misinformation”.

Cervical cancer elimination in the EU is becoming achievable as HPV vaccination coverage rises, a new report says.
As Europe marks European Immunisation Week 2026, the European Centre for Disease Prevention and Control said progress in human papillomavirus vaccination is continuing across the EU and European Economic Area.
All EU and European Economic Area countries now recommend HPV vaccination for adolescent girls and boys as part of their immunisation programmes, marking a major step forward in Europe’s cancer prevention efforts.
Bruno Ciancio, head of unit, directly transmitted diseases and vaccine preventable diseases at the European Centre for Disease Prevention and Control, said: “The elimination of cervical cancer in the EU/EEA is becoming an achievable goal, thanks to the HPV vaccination programmes.
“The progress we are seeing across Europe demonstrates what can be accomplished when countries invest consistently in effective immunisation strategies.
“We are closely monitoring this progress and actively supporting countries to accelerate uptake and move faster towards cervical cancer elimination.”
According to the report, three EU and European Economic Area countries, Iceland, Portugal and Norway, have reached the 2024 EU Council Recommendation target of 90 per cent HPV vaccination coverage among girls by the age of 15.
Fifteen years after HPV vaccination programmes were introduced in Europe, a growing body of evidence confirms the vaccine is highly effective in preventing cervical cancer.
Large-scale studies from Sweden, the Netherlands and Denmark, as well as other parts of the world, have shown significant reductions in HPV infections and precancerous lesions, which are abnormal cell changes that can develop into cancer if left untreated, alongside falling cervical cancer rates among vaccinated women.
Since 2020, European countries have reported a decreased incidence of cervical cancer among vaccinated women.
Studies from Sweden, Denmark and the UK show that early administration of the vaccine increases its full protective potential.
A Swedish study suggested that vaccinating girls before their 17th birthday reduced the incidence of cervical cancer by 88 per cent.
An additional six-year follow-up found a sustained reduction in cervical cancer risk and a population-level decline in invasive cervical cancer incidence after HPV vaccination.
The report showed that vaccination programmes and health system design are critical factors in reaching high levels of HPV vaccination coverage.
Evidence from across Europe showed that school-based vaccination programmes are particularly effective and tend to reach higher levels of coverage among both girls and boys.
