Women with farming and industry jobs have an increased chance of developing breast cancer, a new study has shown.
While cancer research has long explored the links between the most common cancer among women and factors like lifestyle, behaviour and the environment, the study - done by Canadian researchers - is one of the first to look at the impact of a woman's job.
Published in the journal Environmental Health, the purpose of the study was to look at "possible links between breast cancer risk and occupation", with a focus on jobs in the agricultural and industrial sectors.
The study looked at 1006 women with breast cancer and 1146 women without it living in counties in Ontario known for their agricultural and industrial industries. The area was also known for a high proportion of breast cancer cases.
Women working in manufacturing car plastics, canning food or in bars, casinos and racetracks were found to face double the risk over the space of 10 years than those working in other occupations, researchers found.
