New Delhi, 10 July (IANS). According to a new study, air pollution not only damages the heart and lungs, but it can also increase the risk of a normal tumor in the brain, meningooma.
A tumor called meningooma, which is usually carried out in a thin layer (meninges) covering the brain and spinal cord. This tumor is mostly harmless, but sometimes it causes headaches, seizures or these can cause other neurological problems.
In this study published in the Journal of Neurology Journal, researchers found that there could be a possible relationship between pollution and meningooma, although it has not been proved that pollution is the reason for this.
The study analyzed traffic related pollutants such as nitrogen dioxide and ultrafine particles (fine particles), which are found more in urban areas. Researchers found that people who spent more time in contact with these pollutants were high in meningoma.
“Ultrafine particles are so small that they can overcome blood-brain barriers and affect brain tissue,” said Ullawidtfeld, researcher at the Denmark Cancer Institute.
The study was conducted on about 40 million adults in Denmark, whose average age was 35 years and was tracked for 21 years. During this period, 16,596 people were found to have a tumor of the brain or central nervous system, of which 4,645 were meningooma. Research revealed a possible relationship between ultrafine particles and meningooma from traffic. However, there was no strong connection between severe brain tumors and pollutants such as glioma.
“The study suggests that traffic and other sources can increase the risk of meningoma by long -term contact with traffic and other sources. It reflects the effect of pollution on the brain and not only on the heart and lungs.”
He further stated that if clean air may reduce the risk of brain tumors, it can bring a big change for public health. Researchers say more studies are needed to confirm this conclusion.
