Cancer incidence in the industrial corridor: an update.
Because of the high density of industries along the Lower Mississippi River, there is a concern about adverse impact on health, including cancer, among residents in these parishes. This study provides an update of cancer incidence in the Industrial Corridor for the period 1989-93. Age-adjusted cancer incidence rates were calculated for the seven-parish study area from Baton Rouge down to, but not including, New Orleans. Rates were also computed for the entire state of Louisiana and for the combined Surveillance, Epidemiology and End Results (SEER) program. Cancer incidence rates for the Industrial Corridor are either similar to, or lower than, the combined SEER rates for most of the common cancers as well as for rare tumors. The only two exceptions are lung cancer in white males and kidney cancer in white females that are significantly elevated when compared to the SEER averages. Significantly lower rates are found among white males for cancers of kidney, brain, and nervous system, and melanoma; among black males, cancers of all sites combined, oral cavity, stomach, rectum, and prostate, Hodgkin's disease, and non-Hodgkin's lymphoma; among white females, cancers of all sites combined, cervix, uterine corpus, ovary, bladder, and melanoma; and among black females, cancers of all sites combined, oral cavity, lung, breast, ovary, and melanoma. The persistent excess of lung cancer has led to the development of a multi-agency project to evaluate the impact of potential environmental exposures, genetic susceptibility, and their interactions on lung cancer risk. The findings also confirm the urgent need to include and strengthen tobacco prevention and cessation programs in our cancer control activities.
