‘Cancer risk rises with every breath’: study
News.au.com/news/health/cancer-risk-rises-with-every-breath-study-study/article7b9a5e7e-2f8b-4d9d-b7c5-b4f5fb9af7a8 title Scientists uncover link between cancer risk and breathing air pollution article Researchers at the University of Otago have found a link between the exposure to particulate matter and lung cancer risk in both men and women.
The research, which was published in the International Journal of Epidemiology, suggests that men and females with a higher exposure to the air and carbon monoxide are at greater risk of lung cancer.
The study involved over 13,000 men and 11,000 women aged between 45 and 74.
It found that a high level of exposure to carbon monoelectric substances (CO 2 ) was linked to an increased risk of prostate cancer.
“Our findings show that CO 2 is associated with an increased lung cancer incidence in both male and female participants, as well as a lower lung cancer rate in men,” Dr Helen Macdonald, the lead author of the study, said.
“However, our findings did not indicate whether this association was due to CO 2 concentration or to differences in exposure to CO 1 or CO 2 in different age groups.”
Dr Macdonald said the researchers did not find any correlation between CO 2 exposure and lung cancers.
“There is some suggestion that CO 1 exposure is linked to lung cancer, and that this association is stronger for women,” she said.
Dr Macdon said she believed the association between CO 1 and lung Cancer risk was more likely due to other factors, such as the presence of lung disease in the person.
She said there were many other potential explanations for the association.
“Some of these things may be explained by the fact that CO is a component of the ozone layer, and the presence or absence of ozone is important in controlling some of the harmful effects of CO,” she explained.
Dr John Wray, a professor of health policy at Curtin University, said the study was interesting, but more research was needed to understand how the levels of CO in the air impact cancer risk.
“I’m a bit sceptical that it’s all the CO that’s causing it,” he said.
He said the results could help to explain why there had been a rise in CO 2 related cancers in Australia.
“This study does show that the amount of CO released into the atmosphere from coal-fired power plants is a significant contributor to the increasing incidence of lung cancers in the population,” Dr Wray said.
