Thyroid Cancer Information

From the Health Director…

Welcome to our Thyroid Cancer page. I hope that you find the below information helpful.  Iredell County Health Department is committed to bringing you the most current information that we have related to the elevated thyroid cancer rates in the two Mooresville ZIP codes.  I encourage you to review the Summary of Activities document under the Timeline heading below for a brief overview of the reports, initiatives, meetings and research that has been or is currently being done to address this important public health concern.  

Our agency has been working collaboratively with the NC Department of Health & Human Services (NC DHHS), the NC Department of Environmental Quality (NC DEQ), local and state elected officials, Iredell County leaders and other research and academic institutions since this concern was identified.  I also want to acknowledge and thank Ms. Susan Wind for her community advocacy and fundraising work.   

Identifying threats to the health of the public and addressing them is a core part of the public health mission.  Iredell County Health Department will work with our community to provide all the answers that we can.  Preventing disease and protecting the health of our residents remains our highest priority. 


Jane N. Hinson, MS BSN RN

Cancer Survey

North Carolina General Statute 130A-209 requires all healthcare facilities and health care providers that detect, diagnose or treat cancer to report each diagnosis of cancer to the North Carolina Central Cancer Registry.  The North Carolina Central Cancer Registry must have timely and comprehensive reporting of every cancer diagnosis in Iredell County to accurately determine if cancer rates are higher than expected.   Because of the heightened concern regarding cancer diagnosis in Iredell County, the health department has created a brief survey for residents to complete if they have been diagnosed with cancer within the last twenty years.  This survey will not replace the statutory requirement for health care provider reporting but will enhance compliance with the statute.  

When the health department receives a completed survey, it will be sent to the NC Central Cancer Registry.   The Central Cancer Registry will use information from completed surveys to check their own internal records to see if the provider appropriately reported the cancer diagnosis.  If the cancer diagnosis has not been reported, the Central Cancer Registry will contact the provider directly regarding this statutory requirement. 

Please print Cancer Survey and complete by hand

Completed surveys can be mailed, faxed or dropped off at any of the three health department locations that include the main location at 318 Turnersburg Highway, Statesville or the Environmental Health offices at Building Standards, 349 N. Center Street in Statesville or Government Center South, 610 East Center Avenue in Mooresville.  Surveys can also be faxed to 704-878-5357.  Please make sure the surveys are addressed to the health director.  Surveys cannot be completed or accepted electronically to ensure the security of this confidential protected health information.

The health department will be unable to collect this information verbally as currently all personnel resources are dedicated to COVID-19 pandemic response. 

Questions about the survey can be submitted to
