A new study has found that certain occupational exposures may triple the chances of women developing postmenopausal breast cancer. Acrylic, nylon fibers and polycyclic aromatic hydrocarbons are the chemicals that appear to increase the risk. The study looked at occupational exposures. The women worked with the fibers or petrol products. The risk peaked if the exposure occurred before the age of 36. This is a time when breast tissue is still active.

The study is not definitive however adds to the suspicion that environmental and occupational exposures may play a major role in the development of breast cancer. Until more evidence is discovered, women should seriously think about their job choices and choose jobs where air quality and occupational safety is a priority.
