Usmc mos list 19857/30/2023 ![]() ![]() There are no studies which focused solely on associations between the contaminants found in the drinking water at Camp Lejeune and male breast cancer. Painters had an adjusted OR of 2.3 (95 % CI: 1.0-5.2) for male breast cancer while men employed as motor vehicle mechanics had an adjusted OR of 2.1 (95 % CI: 1.0-4.4). The study on exposure to gasoline and combustion by-products found an OR of 2.5 (95 % CI: 1.3-4.5) for men with > 3 months employment in these industries and a lag time of at least 10 years the OR was 5.4 (95 % CI: 2.4-11.9) among men who were under 40 years at the time of first employment in these industries. For male breast cancer, one study investigated occupational exposure to a wide-range of contaminants including industrial solvents and another study investigated exposure to gasoline and combustion by-products. Point estimates above 1 were found in several studies that evaluated female breast cancer and occupational exposure to solvents. Several studies have examined the relationship between breast cancer and occupational exposure to solvents. The age-adjusted incidence rates for female and male breast cancer from CDC WONDER for the United States for 2011 (the most recent year data are available) were 122 per 100,000 and 1.4 per 100,000, respectively. The present study was prompted by concerns from the affected population that the drinking water exposures at Camp Lejeune may have caused male breast cancer. Details about the drinking water contamination have been published elsewhere. The contamination began in the 1950s and continued until the most contaminated wells were removed from service in February 1985. In 1982, the United States Marine Corps (USMC) Base Camp Lejeune, North Carolina, was found to have drinking water supplies contaminated with specific volatile organic compounds including trichloroethylene (TCE), tetrachloroethylene (PCE), vinyl chloride, and benzene. ![]() Exploratory analyses used proportional hazards methods to evaluate associations between exposures and age at diagnosis. We calculated 95 % confidence intervals (CIs) to indicate precision of effect estimates. We conducted exact logistic regression using the 50 th percentile level among exposed controls to create low and high exposure categories. Groundwater contaminant fate/transport and distribution system models provided monthly estimated residential contaminant levels. Base assignment and risk factor information came from military personnel and VA records. Controls were selected from cancers not known to be associated with solvent exposure and included 270 skin cancers, 71 mesotheliomas, and 32 bone cancers. The study included 71 male breast cancer cases and 373 controls identified from the Department of Veteran’s Affairs (VA) cancer registry whose military personnel records were available. We conducted a case–control study among Marines to evaluate associations between residential exposure to contaminated drinking water at Camp Lejeune and male breast cancer risk.
