Researchers from Canada found that a high concentration of ultrafine particles in the air, which are formed as a result of combustion processes, especially diesel fuel, increases the risk of developing tumors in the brain.

Emissions from plants affect lung cancer incidence. The composition of these emissions includes ultrafine particles. Scientists have recently begun to study the effect of these particles on the brain.

Specialists from McGill University analyzed the data of 2 million people from Montreal and Toronto from 2001 to 2016 who were diagnosed with a brain tumor. They looked in the area in which these people lived, as well as how the ultrafine particles were distributed on the ground.

Respondents who were most exposed to ultrafine particles have a greater risk of developing a brain tumor than people who have undergone minimal exposure. Scientists believe that increasing the concentration of these particles in the air on a global scale will increase the number of cancer cases, reports Epidemiology.
