1 case of thyroid cancer found following Fukushima nuclear crisis
A Fukushima prefectural government panel on the health impact from last year's nuclear crisis at the Fukushima Daiichi power plant said Tuesday that one young person has been found to be suffering from thyroid cancer.

The finding was reported at a meeting of the eight-member panel that organized thyroid gland screening for 360,000 residents aged 18 years or younger as of March 11, 2011, when the earthquake and tsunami crippled the power plant.
