sources in the press have reported that the use of diagnosƟc imaging tests has increased across the 
board in the U.S.  Some of these imaging tests may be able to detect tumors by chance, before 
symptoms develop.  Therefore, it is possible that a higher use of  Computed Tomography (CT) scans 
and MagneƟc Resonance Imaging (MRI) are associated with the increase in the incidence of kidney 
cancer.  The study is sƟll in progress, but stay tuned for updates!

Investigating the Incidence of
Childhood Leukemia in California by Ethnicity
  A collaboraƟve research project between invesƟgators at the California Cancer    
  ReporƟng and Epidemiologic Surveillance (CalCARES) Program and UC Berkeley’s 
Center for IntegraƟve Research on Childhood Leukemia and the Environment is currently underway.  
The moƟvaƟon for this research project came from a finding published in the Surveillance, 
Epidemiology, and End Results (SEER) Program’s Cancer StaƟsƟcs Review, 1975‐2011 which indicated 
that the incidence of childhood leukemia increased 55.5 percent between 1975 and 2011 in nine SEER 
regions.  This large increase aroused curiosity regarding the status of childhood leukemia in California 
and highlighted the need to publish current California‐specific trends.  The objecƟves of our study
