Occupation and the high risk of lung cancer in Northeast Florida.

A case-control study involving interviews with 321 male patients with lung cancer and 434 controls, or their next of kin, was undertaken to identify reasons for the high lung cancer mortality along the northeast coast of Florida. In Duval county (Jacksonville), the age-adjusted rate for lung cancer, 1970-1975, among white males was the highest of all urban counties in the United States. Increased risks on the order of 40-50% were associated with employment in the shipbuilding, construction, and lumber/wood industries, particularly among workers with reported exposures to asbestos or wood dust.

Trends of lung cancer in northern Florida.

Although the entire state of Florida has experienced an increase in lung cancer mortality during the present decade, a differential rise among white men has been observed in Duval, a county in its northeastern region. This increase is not explained by population changes or migration of cases. It is hypothesized that an industrial exposure involving paper and pulp manufacturing, shipbuilding, or petroleum may account for these findings.
