According to Michael Gilbertson, the findings found "finding a causal link" between breast cancer and very high exposure to traffic-related air pollution that contains breast cancer-causing substances. A link between night shift work and cancer was also identified. "This new research indicates the role of traffic-related air pollution to contribute to the increasing incidence of breast cancer in the general population," said Gilbertson. The group women developed a cancer believed to have been caused by exhaust gases in which researchers have a brand new "occupational disease". There is one in 10,000 chances that the cases were a coincidence, said the study published in the New Solutions newspaper, because the cancer was so close and close. A review of previous research confirmed that BRCA1 and BRCA2 genes – which try to stop tumors grow – can "silence" through exposures to dioxins and polycyclic aromatic hydrocarbons, both in exhaust gases. BRCA2 deteriorates rapidly in the presence of aldehydes – even components in exhaust gases. "There is much more research to be carried out," said Gilbertson. "But we now have reasonable mechanisms to divert how the BRCA1 / 2 tumor suppressors in this highly exposed border guard became dysfunctional and probably contributed to the ongoing epidemic of sporadic early onset, premenopausal breast cancer among their colleagues." With this new knowledge, industry and government plan for new constructions for industrial and commercial facilities to reduce occupational injury to traffic-related air pollution, "said Gilbertson.
