This study evaluated a culturally and linguistically tailored cancer prevention program delivered by trained Chinese American community health workers to Chinese American adults in Texas. The program focused on breast, colorectal, gastric, liver, and lung cancers and used family health history to provide personalized education and navigation. The study examined whether the program could improve participants' cancer-related knowledge, family health history communication, preventive behaviors, cancer screening, and use of genetic services. The investigators hypothesized that participants would show improvements in these outcomes after receiving the program compared with before the program.
