ABSTRACT

For those neoplasms that have at least 5 occurrences in black persons and 5 occurrences in white persons, determine the relative frequency of occurrence of neoplasms found in the white population compared with the black population. This proportion is obtained using the following equation: relative frequency of occurrence = (number of tumors occurring in whites

divided by the number of white persons) divided by (number of tumors occurring in black persons divided by the number of black persons).
