Female breast cancer and electrical manufacturing: results of a nested case-control study.

Background: A previous explorative record-linkage study suggested a putative role of employment in electrical manufacturing in increasing female breast cancer risk in the Province of Milan (Italy). We deepened the understanding of this possible association in a single large electrical manufacturing plant located in Lombardy in the Province of Milan.

Methods: We carried out a nested case-control study within a cohort of women employed in a large electrical manufacturing plant.

[Female breast cancer and occupational sectors: a preliminary study in the provinces of Lombardy, Italy].

Background: The role of occupational exposures in breast cancer development is still uncertain. A recent paper showed increased risks in some occupational sectors in Lombardy, Italy. We deepened this analysis at the level of single provinces of the same Italian region.

Female breast cancer in Lombardy, Italy (2002-2009): a case-control study on occupational risks.

Background: The role of occupational exposures in breast cancer development is still uncertain and, to our knowledge, no studies have been recently carried out in Italy to provide a comprehensive estimation of this possible risk.

Methods: Based on administrative data, a case-control study was carried out recruiting all incident cases of female breast cancer in the period 2002-2009, aged between 35 and 69 years, residing in Lombardy, Italy. Controls were randomly sampled from all women residing in Lombardy as of December 31, 2005.

[A follow-up study of 304 cases of suspected pathology caused by benzene seen in 1950-71].

A group of 304 subjects admitted to the Institutes of Occupational Health of Milan and Pavia (Italy) between 1951 and 1970 for suspected benzene intoxication were retrieved from hospital records and their mortality experience was examined up to 31 December, 1986. The aims of the study were: 1) to estimate, in quantitative terms, the risk associated with benzene exposure in that area in the time period considered (these risks had already been reported, but merely as case reports); 2) to investigate the possibility of an increased frequency of neoplasms other than leukaemia; and 3) to further investigate the exposure history of these subjects. In the absence of data on the population at risk, mortality was analysed via the mortality odds ratio (MOR) method.

Exposure to formaldehyde and cancer mortality in a cohort of workers producing resins.

The mortality of 1,332 male workers employed at least 30 days in 1959-1980 in a resins-manufacturing plant was examined. Ambient measurements taken in the plant between 1974 and 1979 documented a potential for exposure to levels of formaldehyde as high as greater than 3.0 mg/m3.
