Description
For sample female adults ages 30 and over who ever had a mammogram (MAMEV) and had their first mammogram before age 50 or don't know or refused to say when they had their first mammogram (MAM1AGEG) and are currently less than 50 years old, MAM1Y reports the main reason why she had her first mammogram. The verbatim responses given by women were categorized by the interviewer using the codes reported on the Codes tab. Prior to 2019, MAM1Y was asked of sample female adults ages 30 and over who ever had a mammogram before age 40. Please see MAMEV for other related variables.
