A mammogram is a screening tool used to screen for breast cancer. According to the Center of Disease Control and Prevention (CDC) breast cancer is the most common cancer among women and is one of the three most common cancers that causes death among women . For these reasons it is important for women who meet the breast cancer screening guidelines to undergo screening to detect any abnormalities or cancer early to quickly begin treatment. Today’s map of the day shows the percent of women who received mammogram screening in 2013 by county. From the map we can see some counties are shaded darker than others, indicating a higher percentage of women in these counties received mammogram screenings, such as counties within New York, Maine, and Road Island. In contrast, we can see some counties within states such as, Texas, Nevada, Arizona, Oklahoma are shaded yellow/light orange indicating a low percent of women received mammograms.
