Based on research, traffic pollution can lead to breast cancer risk in women. Researchers from McGill University and the University of Montreal said the number of cases of breast cancer in areas of high nitrogen dioxide levels rise, as quoted by the Daily Mail.
Mark Goldberg, one of the researchers said the study was started because there is currently no research investigating the relationship between air pollution and breast cancer with the mapping of air pollution.
"We've seen the rate of breast cancer rises for some time. No one knows why, and only about a third of cases associated with risk factors. Because no one studied the relationship between air pollution and breast cancer using detailed air pollution maps, we decided to investigate, "said Goldberg, a researcher from the" Research Institute of the McGill University Health Centre "in Canada.
The researchers found an association between post-menopausal breast cancer and exposure to nitrogen diokasida. Women living in areas with the highest pollution levels likely to get breast cancer twice.
"We found an association between post-menopausal breast cancer and exposure to nitrogen dioxide, which becomes a marker for air pollution-related traffic. Throughout Montreal, levels of nitrogen dioxide (NO2) varied between five parts per billion to 30 parts per billion," said Goldberg.
"Another way to say it is the women who live in areas with the highest pollution levels likely to get breast cancer are two times more than those living in areas with low pollution."
Goldberg warns that these disturbing results should be interpreted with "great caution." He added that does not mean NO2 causes breast cancer.
"First of all, this does not mean NO2 causes breast cancer. This gas is not the only pollutants produced by cars and trucks, but it was there, as well as other gases, particles and compounds we associate with past traffic, some known to cause cancer. No2 only marker of cancer-causing agent is not the truth. "
The study combined data from previous studies. The researchers used the results of the study year 2005/2006 to create two "maps" of air pollution. "Map" that shows the level of NO2 in different parts of the city in 1996 and ten years earlier in 1986.
The researchers then mapped the home addresses of women diagnosed with breast cancer in our study of air pollution in 1996/1997. It shows the number of patients with breast cancer are higher in areas with higher air pollution levels.
The results have been published in the journal Environmental Health Perspectives.
