Discrimination has been shown as a major causal factor in health disparities, yet little is known about the relationship between perceived medical discrimination (vs. general discrimination outside medical settings) and cancer screening behaviors. We examined whether perceived medical discrimination is associated with lower screening rates for colorectal and breast cancers among racial and ethnic minority adult Californians. Pooled cross-sectional data from 2003 and 2005 California Health Interview Surveys were examined for cancer screening trends among African-American, American-Indian/Alaskan-Native, Asian, and Latino adult respondents reporting perceived medical discrimination compared to those not reporting discrimination (n=11,245). Outcome measures were dichotomous screening variables for colorectal cancer among respondents, ages 50 -75; and breast cancer among women, ages 40 - 75. Women perceiving medical discrimination were less likely to be screened for colorectal (OR = 0.66; CI = 0.64 - 0.69) or breast cancer (OR = 0.52; CI = 0.51 - 0.54) compared to women not perceiving discrimination. Although men who perceived medical discrimination were no less likely to be screened for colorectal cancer than those who did not (OR = 1.02; CI = 0.97 - 1.07), significantly lower screening rates were found among men who perceived discrimination and reported having a usual source of health care (OR = 0.30; CI = 0.28 - 0.32). These findings of a significant association between perceived racial or ethnic-based medical discrimination and cancer screening behaviors have serious implications for cancer health disparities. Gender differences in patterns for screening and perceived medical discrimination warrant further investigation.
