SEOUL, South Korea (AP) — A South Korean government agency said Friday that working at a Samsung Electronics factory caused the breast cancer of a worker who died earlier this year, only the second time it has recognized a link between cancer and Samsung’s chip plants.

The Korea Workers’ Compensation and Welfare Service, which is part of the labor ministry, ruled earlier this month that there was a “considerable causal relationship” between the woman’s cancer and her five years of work at a semiconductor plant near Seoul. The ruling didn’t become public until Friday when the agency announced compensation for the woman’s family.
