We have been following the story about a potential cancer cluster that has caused thyroid cancer in teens living within a few miles of each other. The parents have been seeking help and answers to determine if there is an environmental cause. The parent group stated they had approached the state and county and felt they were being ignored in the request to have the water in the area tested. Last week, the city stepped up and offered to investigate.

After the story came out about the Trenton teens, one of the parents said the parent group has been contacted by six other people in the area with thyroid cancer.

In a new development, Cincinnati News 5, who is following this story closely, and investigating information as it becomes available, recently aired an interview with Dr. Peter Rickards of Idaho, who has been investigating other thyroid cancer cases in the Pacific Northwest linked to radioactive fallout from nuclear tests.

According to Dr. Rickards, drinking milk from cows who grazed in dairy fields contaminated with radioactive iodine-131 has been linked to increased cases of thyroid cancer in the Pacific Northwest.

Dr. Rickards suggests the parents and investigators in Trenton look for a fresh source of radioactive iodine in the neighborhood.

Dr. Rickards went on to suggest that they need to take a look at how medical incinerators and cancer clinics have been disposing of iodine-131, perhaps incorrectly, and that might possibly be a source of contamination. He doesn't say this is the definitive cause for the unusual number of young people being diagnosed with thyroid cancer in Butler County -- only that it might be a good place to start looking for answers.
