Cancer in south Louisiana. Part 1: Tobacco-related cancers

Tobacco-related cancers comprise about one third of the newly-diagnosed cancer in South Louisiana. These cancers are three times more common in men than in women. For cancers originating from anatomic sites where there is a direct contact with tobacco, ie, lung, larynx, oral cavity and pharynx, and esophagus, incidence rates for blacks are either higher than or similar to the rates for whites. For cancers of the bladder and the kidney, sites which have no direct contact with tobacco products, incidence rates are higher in whites than blacks. In general, white men in South Louisiana tend to have risks significantly higher than national for tobacco-related cancers, in particular, cancers of the lung (31% higher) and the larynx (42% higher). A similar pattern is observed for white females but is less pronounced. Black men in South Louisiana, on the other hand, have significantly lower rates than the SEER averages for cancers of the esophagus, oral cavity, and pharynx. Risks for other tobacco-related cancers are very comparable. There are very small differences in rates for black women between South Louisiana and SEER areas. Tobacco-related cancers are most preventable. Any effective cancer program in Louisiana must emphasize prevention and cessation of tobacco use.
