Adjusted weighted percentages of cancer reports with varying levels of consistency and site specificity in relatives with a positive cancer history

NOTE: After identifying 2,408 relatives (781 first-degree and 1,627 second-degree) with a cancer history, the 1,019 respondents were asked to report the cancer type or where in the body the cancer started. All percentages of cancer reports are weighted to the Connecticut population and adjusted for differential selection probabilities, rates of nonresponse, and poststratification.
