Effects of the Chernobyl Disaster on Thyroid Cancer Incidence in Turkey after 22 Years

Abstract EN

Background.

Separate studies involving people who survived atomic bombs have shown that the risk for cancer remains high after 40 years, compared with the risk in the general population.

An elevated risk may also remain in regions of Turkey near the Chernobyl disaster.

Patients and Methods.

A multidisciplinary study conducted in 2008, 22 years after the Chernobyl disaster, examined the thyroid cancer incidence in Rize, a province of Turkey located on the shore of the middle Black Sea.

Approximately 100,000 people were screened, and a fine-needle aspiration biopsy was performed in 89 patients.

Results.

Based on postoperative histopathological examinations, thyroid cancer was diagnosed in six of the 100,000 people screened.

Conclusion.

Given a thyroid cancer frequency of approximately 8 in 100,000 in the Turkish population, according to the Turkish Cancer Research Association, the rate in Rize reflects no increase in the thyroid cancer incidence 22 years after the Chernobyl disaster.
