Information about the health effects of GenX is limited.  Laboratory studies in which animals were exposed to different levels of GenX  did show adverse effects to the liver and blood, along with liver, pancreatic, testicular and uterine cancers, but there is no information about whether these or other health effects would be seen in humans.  A recent review of cancer rates over the last 20 years in Bladen, Brunswick, New Hanover, and Pender counties indicated that the rates in those counties were generally similar to the statewide rates of pancreatic, liver, uterine, testicular and kidney cancers.  However, no conclusions can be drawn as to whether GenX or any other specific exposures contributed to cancer rates that were examined.
The Centers for Disease Control (CDC) has committed to doing an assessment on the possible long-term health effects of GenX.  The North Carolina Department of Health and Human Services has reviewed existing research studies and is working with the EPA, CDC, and academic researchers to gather more health information about GenX and related chemicals.  .
