Cancer Screening

Health Promotion: Early Detection of Disease and Disease Prevention

Disease prevention and early detection is an integral part of the discipline of Family Medicine and is well suited for study in the primary care setting. Research on colorectal cancer (CRC) screening focuses on addressing disparities in CRC screening. Qualitative methods have been used to explore awareness of cancer and screening within a multiethnic patient population. These findings have been utilized in the design of a quantitative study to estimate the prevalence of CRC screening within a clinic population. An ongoing study focuses on patient preferences for attributes associated with the four different CRC screening tests that are recommended for screening.
