Objective To assess the contemporary incidence of cancers using American Samoa as a learning set for insights into similar populations. Methods A retrospective observational analysis of de‐identified data held in public‐access databases (2004–2014) and data on uterine cancer from a hospital, both in American Samoa (2015–2016). Results There were 341 new cases of cancer in 2004–2014 (111 per 100 000 women/year), including breast (20.2%), uterine (19.4%), and cervical (5.0%); and 287 in 2011–2015 (103 per 100 000 women/year), including uterine (24.0%), breast (18.5%), and cervical (5.2%). Uterine cancer increased from 21.4 to 60.3 per 100 000 women/year, becoming the most common cancer in American Samoa. In 2011–2015, the incidence‐rate ratio of uterine cancer to other cancers in American Samoa was 1.3‐, 3.8‐, 4.6‐, 7.7‐, and 23‐fold higher than breast, colon, cervical, ovarian, and lung cancer, respectively. Among the most recent cases (n=33), median age was 55 years (10 [30.3%] <50 years), median BMI was 38.2; and 11 (33.3%) cases had grade 3 histology. Conclusion The pattern of cancers in American Samoa differs from that in the US mainland. The findings reflect significant changes in cancer incidence. Cancer control programs should evaluate the potential of uterine screening in accordance with their community's needs and characteristics.
