CNCOLRECT identifies sample adults who had ever been told that they had colorectal cancer. Those sample adults who reported ever being told by a doctor or other health professional that they had cancer or a malignancy of any kind (CANCEREV) were asked the follow-up question, "What kind of cancer was it?"

Interviewers marked up to three kinds of cancer specified on the survey form, and noted when the respondent mentioned more than three types of cancer. Responses of colon or rectal cancers were recoded to "colorectal" cancer. In previous years, these cancers were identified in separate variables (CNCOLN, "Colon" and CNRECT, "Rectal."

See CNBLAD for a list of related cancer type variables.
