STUDY AT A GLANCE
This study is about:
How breast cancer prevalence and mortality differs between the Hispanic women of different descent (Cuban, Mexican, Puerto Rican, and Central and South American) in the United States.
Why is this study important?
Public health researchers typically group people from all Hispanic subgroups into one category. But research on differences in mortality and (how often a disease occurs in an area) revealed many differences regarding health outcomes and behaviors among Cuban, Mexican, Puerto Rican, and Central and South American people. By combining all of the information on these subgroups into one Hispanic category, researchers are not getting an accurate picture of any subgroup.
Study findings:
- This study found that the overall breast cancer mortality rate per 100,000 women in each group was:
- all Hispanic women in the United States: about 18 deaths
- women of Cuban descent: about 18 deaths
- women of Mexican descent: about 19 deaths
- women of Puerto Rican descent: about 19 deaths
- women of Central or South American descent: about 10 deaths
What does this mean for me?
The results of this study suggest that breast cancer mortality rates for Hispanic women differ based on the country of origin. More work needs to be done to understand the biological reason why these differences may exist. Hispanic women should work with their health care providers to determine their breast cancer risk and discuss the appropriate time to start screening and ways to lower their breast cancer risk.

IN DEPTH REVIEW OF RESEARCH
Study background:
Even though research indicates many differences between Hispanic subgroups (Cuban, Mexican, Puerto Rican, and Central and South American), the authors state that “one topic on which there continues to be a lack of data is breast cancer,” despite the fact that breast cancer is the most commonly diagnosed cancer and leading cause of cancer death in Hispanic women in the United States.
It is important to understand if and how Hispanic women of certain countries of origin are more affected by breast cancer death than others, so that interventions can be developed for those who most need them.
Bijou Hunt from the Sinai Urban Health Institute published work in the 2016 issue of the Journal of Cancer Epidemiology that examined the prevalence and mortality rates of different Hispanic subgroups.
Researchers of this study wanted to know:
Do mortality rates differ between American Hispanic women of Cuban, Mexican, Puerto Rican, and Central and South American descent?
Population(s) looked at in the study:
This study used self-reported data from the American Community Survey (ACS), the National Health Interview Survey (NHIS), and death files from the National Center for Health Statistics. The ACS data was from 2013 and included sociodemographic variables such as population size, the percentage of Hispanic population comprised by each subgroup, the percentage of the population between ages 18 and 64, and high school graduate status. The NHIS data was from 2009 to 2013 and was used to calculate female breast cancer prevalence for women between ages18 and 64 for all of the subgroups. Data sources, including Hispanic origin and self-reported country of origin, for both the ACS and NHIS are self-reported by participating individuals. Race and ethnicity is reported by the funeral director; death files were used to help calculate breast cancer mortality rates.
Study findings:
- Overall, the breast cancer prevalence rate for all Hispanic women in the United States (both U.S. and foreign born) was 1.03%. Breast cancer prevalence rates for individual Hispanic groups included:
- U.S. and foreign-born women of Mexican descent: about 0.92%
- Puerto Rican descent: about 1.53%
- Central and South American descent: about 0.94%
- Cuban descent: The researchers were unable to develop an accurate prevalence rate
- Overall, the breast cancer mortality rate for all Hispanic subgroups was about 18 deaths per 100,000 women. Deaths per 100,000 women in each group included:
- women of Cuban descent: about 18 deaths
- women of Mexican descent: about 19 deaths
- women of Puerto Rican descent: about 19 deaths
- women of Central or South American descent: about 10 deaths
Limitations:
If the population studied for this study had lower insurance coverage and/or health care access, the number of breast cancer cases may have been underestimated. This may reduce breast cancer prevalence data in some groups and produce inaccurate estimates.
Because Central and South American populations in the U.S. are small, the researchers were unable to explore any differences between those two groups and instead had to combine them into one study group (Central and South Americans), which may have masked differences between countries in those regions. Finally, Hispanic women can be of any race, but this study looked only at country of origin and not race.
Conclusions:
This study suggests that Hispanic women of different countries of origin have different breast cancer mortality rates. According to the authors, “The Hispanic population is young, heterogeneous, and growing, which means that understanding and addressing this group’s diverse health needs is of great importance to the overall health of the nation.” More work needs to be done to understand why differences exist among the subgroups, but patients and their healthcare providers should work together to determine breast cancer risk and screening strategies.
