TOKYO (Kyodo) -- Yoshiko Tanaka, a former member of the 1970s female pop trio the Candies, died Thursday of breast cancer at a Tokyo hospital, her husband said. She was 55.
Tanaka, whose real name was Yoshiko Odate, was diagnosed with breast cancer in her late 30s and underwent surgical treatment, but the disease repeatedly returned, said Kazuo Odate, her businessman husband, who held a press conference at the hospital.
