(TOKYO) -- The director of Japan's crippled Fukushima Daiichi nuclear power plant, who abruptly resigned last month, has been diagnosed with esophageal cancer.
Masao Yoshida disclosed his condition to workers at the plant on Friday and TEPCO, the plant's operator, confirmed it at a press conference in the afternoon. The severity of Yoshida's cancer, however, has not been revealed.
Citing a doctor at the National Institute of Radiological Sciences, TEPCO said the cancer was not likely triggered by radiation exposure, adding that it usually takes five to 10 years for a person to develop cancer from radiation.
TEPCO also said that Yoshida had been exposed to 70 millisieverts of radiation since the nuclear disaster began in March, which is below the 100 mSv limit for emergency workers.
