Many Korean Americans (KAs) suffer high cancer incidence levels and have low cancer screening rates. A significant number of KAs lack adequate information about cancer screening tests. However, little is known about the health information seeking behaviors of KAs. This study examines the types of cancer information searched for, the cancer information seeking experiences, and the awareness of major cancer information sources, such as the National Cancer Institutes (NCI) and the NCI's Cancer Information Service, among KAs. It also examines associations with demographic characteristics and media use influencing variations in the awareness of cancer information sources. Data for this study were gathered with a cross-sectional, community-based survey (254 KAs). The survey results indicated that KA's involvement in cancer information seeking is relatively low, and they have somewhat negative experiences in seeking cancer information. In addition, their awareness of cancer information sources was limited. Despite of the heavy use of Korean ethnic media, it did not connect to cancer information source awareness. Rather, use of US mainstream media was significantly related with awareness. Campaigns using the Korean language through partnerships with Korean ethnic media to inform KAs about credible sources of health information appear to be warranted by our findings.
