Cervix and breast cancer incidence in 1978-82 was computed for immigrant and United States-born Black women in Brooklyn, New York. Compared to the national SEER (Surveillance, Epidemiology and End Results) rates, US-born and Haitian women had high rates of invasive cervical cancer, while English-speaking Caribbean immigrants had an average rate. However, while US-born women had an average rate of carcinoma in situ of the cervix, both immigrant groups had low rates. Both immigrant groups had low rates of breast cancer, whereas US-born Black women had an average rate.
