August 24, 2015 - Red Butte Creek Cancer Incidence Statistical Review (Five-Year Update): The Utah APPLETREE has completed a statistical review of cancer incidence in the neighborhoods surrounding Red Butte Creek in Salt Lake City, UT. This study provides a five-year update to the cancer review completed immediately following the 2010 oil spill into the creek. Of the 42 cancer types evaluated, only the incidence of ovarian cancer during the last time period (2008 - 2012) was meaningfully elevated when compared to the rest of the state. As that was the final analytical period, it may represent an emerging cluster. However, exposure to crude oil or its components is not known to be a risk factor for ovarian cancer.
