Breast cancer

Abstract

Breast cancer is the most common neoplasm in women, and it occurs rarely also in men. A handful of occupational exposures, including ethylene oxide and shift work that involves circadian disruption, have been linked, to an increased risk of breast cancer in women, though nonehave yet been linked to male breast cancer. As the most common cancer among women, breast cancer represents an important burden on our societies. There are no certainties regarding the importance of occupational, or environmental, exposures in the etiology and development of breast cancer, but the fact that only about 30 % of the risk can be explained by known risk factors means that continued research on the relationship between occupational exposures and breast cancer is warranted.
