Community health workers can successfully identify Latina women who might benefit from genetic cancer testing and significantly increase their knowledge about cancer risk factors, according to a 2026 study of 156 women in California. However, only 22% of participants were offered genetic testing, and just 18% of those accepted it, with cost concerns, time constraints, and fear of results serving as major barriers to pursuing testing.
A new program in California showed that community health workers, who are trusted members of local communities, can help identify Latina women who might benefit from genetic testing for cancer risk. Researchers followed 156 Latina women over 2.5 years and found that when community health workers provided cancer screening and education, women learned more about cancer prevention. However, only 22% of women were offered genetic testing, and just 18% of those decided to pursue it. The study shows that community health workers are effective at reaching and educating women about cancer risk, but many barriers like cost concerns and time constraints still prevent women from getting genetic tests.
Key Statistics
A 2026 study of 156 Latina women in California found that community health workers significantly increased women’s awareness of cancer risk factors including diet, exercise, and weight, with improvements measured at 4-month follow-up.
Of 156 Latina women screened by community health workers for genetic cancer risk, 33 women (22%) were identified as candidates for genetic testing, but only 6 women (18% of those offered) expressed interest in pursuing it.
In a 2026 California study, Latina women cited cost concerns, competing family health priorities, lack of time due to work and caregiving, and fear of test results as primary reasons for declining genetic cancer testing despite being identified as good candidates.
The Quick Take
- What they studied: Whether community health workers could help identify Latina women who should get genetic testing to learn about their cancer risk
- Who participated: 156 Latina women in Salinas Valley, California, with an average age of 43. Most had high school education or less (78%), and most earned less than $35,000 per year (72%)
- Key finding: Women who worked with community health workers significantly increased their knowledge about cancer risk factors like diet and exercise. However, only 22% were offered genetic testing, and just 18% of those accepted it
- What it means for you: Community health workers from your own community can help you understand your cancer risk and connect you to screening. However, cost, time, and concerns about test results remain real barriers that need to be addressed
The Research Details
Researchers created a partnership between a university and the Salinas Valley community to develop a cancer prevention program. From October 2020 to May 2023, community health workers met with 156 Latina women to provide cancer screening and education. The community health workers were trained to identify women who might benefit from genetic testing, which looks at your DNA to see if you have a higher risk for certain cancers.
Participants completed surveys at the start of the program and again four months later. These surveys asked about their age, education, income, health knowledge, and what they learned about cancer prevention. Researchers measured whether women’s knowledge about cancer risk factors improved and how many women were interested in genetic testing.
The program focused on breast cancer, cervical cancer, and colon cancer screening. Community health workers provided education about how diet, exercise, weight, and other lifestyle factors affect cancer risk. They also screened women to see if they had family history or other signs suggesting genetic testing might be helpful.
This research approach is important because it tests whether trusted community members can help reach women who might not otherwise access genetic testing. Many Latina women face barriers to healthcare, including language differences, cost concerns, and lack of trust in medical systems. By using community health workers from the same communities, researchers could test whether this approach makes genetic screening more accessible and acceptable
This study has several strengths: it followed real people over 2.5 years, it measured actual behavior changes, and it included detailed demographic information. However, the study was relatively small (156 women) and took place in one specific region of California, so results may not apply everywhere. The study did not include a comparison group of women who did not receive the program, so we cannot be completely certain the improvements came from the program itself. Additionally, only 153 of 156 women completed the genetic risk screening, and only 6 women actually pursued genetic testing, which limits what we can learn about testing outcomes
What the Results Show
Women who participated in the program significantly increased their awareness of cancer risk factors. Specifically, they learned more about how high-fat diets, not eating enough fruits and vegetables, lack of exercise, and being overweight increase cancer risk. They also learned about ways to slow down the development of colon cancer, lung cancer, and skin cancer. These improvements were statistically significant, meaning they were unlikely to have happened by chance.
Of the 156 women enrolled, 153 completed the genetic risk screening. Based on this screening, 33 women (22%) were identified as potentially benefiting from genetic testing. However, only 6 of these 33 women (18%) actually expressed interest in pursuing genetic testing. This shows a significant gap between identifying women who could benefit from testing and actually getting them to accept it.
Women reported high satisfaction with the community health worker program. They appreciated having someone from their community explain cancer prevention in a way they could understand. The program successfully reached women who might not otherwise seek cancer screening services.
The study identified several important barriers preventing women from pursuing genetic testing. Women cited low perceived cancer risk as a reason for not wanting testing, meaning they did not believe they were personally at high risk. Other barriers included competing health priorities within their families, lack of time due to work and caregiving responsibilities, concerns about the cost of testing, and fear of what the test results might reveal. These findings suggest that identifying women who could benefit from testing is only the first step; addressing these practical and emotional barriers is equally important
According to Gram Research analysis, this study builds on previous research showing that community health workers can improve health outcomes in underserved communities. Earlier studies demonstrated that community health workers increase cancer screening rates and health knowledge. This research extends that work by specifically testing whether community health workers can identify and refer women for genetic testing. The finding that only 18% of eligible women pursued testing aligns with other research showing that genetic testing uptake remains low even when women are identified as good candidates, suggesting that barriers beyond identification need attention
The study did not include a control group of women who did not receive the program, so we cannot be completely certain that the knowledge improvements came from the program rather than other factors. The study took place only in Salinas Valley, California, so results may not apply to Latina women in other regions with different healthcare systems or resources. The very low number of women who actually pursued genetic testing (only 6 women) means we learned little about what happens after testing. The study relied on self-reported surveys, which can be less accurate than objective measurements. Additionally, we do not know the long-term impact of the program or whether women maintained their increased cancer knowledge over time
The Bottom Line
If you are a Latina woman, consider working with a community health worker to learn about your cancer risk factors. Community health workers can help you understand whether genetic testing might be right for you. If cost is a barrier, ask about financial assistance programs. If you have concerns about test results, talk with a genetic counselor who can explain what the results mean and how they might affect your health decisions. Confidence level: Moderate. The evidence shows community health workers are effective at education and screening, but more research is needed on how to increase genetic testing uptake
This research matters most for Latina women, particularly those with limited access to healthcare, lower income, or language barriers. It also matters for healthcare organizations and community leaders working to improve cancer prevention in underserved communities. Healthcare providers should consider how to partner with community health workers to reach women who might benefit from genetic testing. This research is less directly relevant to women with high income and easy access to healthcare, though the barriers identified may still apply to some
You should expect to see increased knowledge about cancer risk factors within a few months of working with a community health worker. However, deciding whether to pursue genetic testing may take longer as you consider your personal situation, family history, and concerns. If you do pursue testing, results typically come back within 2 to 4 weeks. Changes in health behaviors based on this knowledge may take several months to show measurable effects
