Cancer incidence rates among blacks in urban and rural Georgia, 1978-82.

The records of the Atlanta Cancer Surveillance Center were reviewed for all incident cases of cancer diagnosed among Black residents of the catchment areas during calendar years 1978 through 1982. The resultant age-adjusted overall cancer incidence rates for urban Blacks were greater than those for rural Blacks. The largest urban excess was found for cancers of the buccal cavity and pharynx. Urban residence also was associated with lung and prostate cancers among males, and pancreatic cancers among females.
