Air pollution significantly increases risk of breast cancer
this High particle concentration in suspensionA substance commonly found in the air we breathe in cities significantly increases the risk of breast cancer. High particle concentration in the air we breathe in cities significantly increases the risk of breast cancer, according to a survey conducted by the European Society for Medical Oncology (ESMO). The study, led by Béatrice Fervers, a researcher at the León Bérard Cancer Center in France, found that high particle concentration (PM2.5), which is found to have the same effect on breast tumors as the associated risk factors for breast cancer. The study also found that exposure to larger suspended particles (PM10) or nitrogen dioxide Start the exhaust pipe, which increases the risks of developing lung cancer by 28% when exposure to these toxins increases by 10 micrograms per cubic meter. The European Parliament is in talks with other European institutions to agree on reform of air quality directive. The EU aims to lower the maximum legal threshold for particles in cities from 25 microgram to 10micrograms by 2030, a more ambitious target than originally proposed by the EU.

this High particle concentration in suspensionA substance commonly found in the air we breathe in cities significantly increases the risk of breast cancer. This is revealed in one of the most high-profile surveys presented at the European Society for Medical Oncology (ESMO) congress, where dozens of leading cancer experts from across the continent gather in Madrid between this week and next week.
These particles, called PM2.5, are small bodies about a hundred times smaller in diameter than a human hair. Floating in the atmosphere, its main source is human activitiesIn particular, exhaust gases are produced by diesel vehicles and heaters and chimneys in homes, factories and power plants that burn wood and fossil fuels.
PM2.5 is considered the deadliest polluting element around cities due to its extremely small size. They easily penetrate the lungs and alveoli They enter the bloodstream and cause or worsen respiratory conditions such as bronchitis, asthma or chronic obstructive pulmonary disease, and increase the likelihood of stroke or heart disease. They are blamed for tens of thousands of emergencies and hospitalizations every year, especially among children and the elderly, and thousands of deaths in Spain alone.
Science has now established that cancer must be included in the list of serious health hazards.Research completed last year by Charles Swanton of the Francis Crick Institute in London showed Excessive respiratory particles cause lung cancer among non-smokers.The study, led by Béatrice Fervers, a researcher at the León Bérard Cancer Center in France, has now shown that PM2.5 has the same effect as the associated risk factors, but for Breast tumors.
Fervers’ work included comparing exposure to air pollutants at home and in the workplace among nearly 2,500 women diagnosed with breast cancer over a 21-year period from 1990 to 2011, compared with nearly 3,000 other French women who did not have breast cancer. Compare. disease.The conclusion of this work is The risk of developing these tumors increases by 28% When exposure to suspended particles increases by 10 micrograms per cubic meter, this is approximately equivalent to the difference in average PM2.5 concentrations in urban centers or rural environments.
Researchers also found that exposure to larger suspended particles (PM10) or nitrogen dioxide Start the exhaust pipe. Indeed, the scientific team now hopes to complete an analysis of the damage air pollution may have on the development of this tumor by studying exposure to these toxins on the way to work, suspecting that this may hide a significant increase in risk.
Charles Swanton attaches great importance to the results of this study and believes it is important to study whether contamination allows pre-existing mutated breast tissue cells to promote tumor growth, “possibly through a process similar to what we see in non-smoking breast patients.” Inflammatory processes observed in cancer. “Lung cancer”.
Jean-Yves Blay, Director of Public Policy at ESMO, stressed the relevance of the two experts’ findings and called on health authorities to act accordingly. “There is now strong epidemiological and biological evidence linking PM2.5 exposure and cancer, so we have strong clinical and economic justification Reduce pollution and prevent cancer“.
In fact, oncologists have issued a formal “urgent appeal” to the EU to lower the limit to one-fifth of the current limit in light of evidence that particulate matter is highly dangerous to health. Permissible PM2.5 concentrations in cities in 27 member states.
ESMO, aligned with the majority of the European Parliament and the World Health Organization, is in ongoing negotiations with other European institutions to Agreement agreed on reform of air quality directive. The European Parliament is trying to persuade the European Commission and Council to agree to lower the upper limit on the average annual concentration of PM2.5 from the current 25 micrograms per cubic meter to 5 micrograms. This is a more ambitious target than originally proposed by the EU. The European Commission aims to lower the maximum legal threshold for particles in cities from 25 micrograms to 10 micrograms by 2030.
“We have a responsibility to drive this change not just for the people of Europe, but for people around the world, where pollution conditions vary greatly,” Bligh said. He believes that by backing our demands with solid scientific evidence , we are providing a new dimension to public health policy. “The work is not done yet and change will not happen overnight, but Are we heading in the right direction?“said the representative of European oncologists.
