Tri-Counties Cancer Studies

In April 1997, the Tri-Counties Regional Cancer Registry released the results of cancer rates in the communities in Ventura County surrounding SSFL . The report concluded, "My conclusion from this simple preliminary analysis is that residents of the study area seem to have cancer incidence risk which is similar to that of the other residents of the Tri-Counties region, except for leukemia in women which is significantly lower, and cancer of the lung & bronchus which is higher."

In October 2006, the Tri-Counties Cancer Surveillance Program conducted a study of census tract 75.03, encompassing a 2-3 mile radius surrounding SSFL in Ventura County. The conclusion, which is documented in the letter below is that the “Based on this analysis I conclude that occurrence of newly diagnosed invasive cancers in census tract 75.03 in Ventura County, does not show any unusual pattern and has actually decreased by 7.5 percent from 1988 through 2004."
