Health Indicator Report of Breast Cancer Screening (Mammography)
Breast cancer is the most commonly occurring cancer in U.S. women (excluding basal and squamous cell skin cancers) and the leading cause of female cancer death in Utah. Deaths from breast cancer can be substantially reduced if the tumor is discovered at an early stage. Mammography is currently the best method for detecting cancer early. Clinical trials and observational studies have demonstrated that routine screening with mammography can reduce breast cancer mortality by about 20% for women of average risk.^1^ The U.S. Preventive Services Task Force recommends that women 50-74 years of age undergo mammography every two years, while the American Cancer Society recommends that women aged 40-44 should have the choice to start annual screenings, women 45-54 years old should have annual mammograms, and women 55 and older should have mammograms every other year as long as they are healthy and likely to live for 10 or more years. Women who are at higher than average risk of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and the frequency of that screening. If you are 40 or over, talk to your doctor about which recommendations are best for you. ''1. Myers ER, Moorman P, Gierisch JM, et al. Benefits and harms of breast cancer screening.

Mammogram Within the Past Two Years by Race, Utah, 2012-2014
NotesAge-adjusted to the U.S. 2000 standard population.
Data SourceUtah Data: Behavioral Risk Factor Surveillance System, Office of Public Health Assessment, Utah Department of Health
Data Interpretation IssuesTo reduce bias and more accurately represent population data, the BRFSS has changed survey methodology. In 2010, it began conducting surveys by cellular phone in addition to landline phones. It also adopted "iterative proportional fitting" (raking) as its weighting method. More details about these changes can be found at: [http://health.utah.gov/opha/publications/brfss/Raking/Raking%20impact%202011.pdf].
DefinitionThe proportion of women 40 years or older who reported having a mammogram in the last two years.
NumeratorThe number of women 40 years or older who reported having a mammogram in the last two years.
DenominatorThe total number of female survey respondents aged 40 or older excluding those who responded "don't know" or "refused" to the numerator question.
Healthy People Objective C-17:Increase the proportion of women who receive a breast cancer screening based on the most recent guidelines
U.S. Target: 81.1 percent
State Target: currently being revised
Other ObjectivesCSTE Chronic Disease Indicators
How Are We Doing?Between 1989 and 2010, the percentage of Utah women aged 40 or older who reported receiving a mammogram within the last two years increased from 51.6 percent to 66.4 percent. To reduce bias and more accurately represent population data, the BRFSS changed survey methodology in 2010. It began conducting surveys by cellular phone in addition to landline phones. It also adopted "iterative proportional fitting" (raking) as its weighting method. Based on this methodology, Utah's 2014 rate was 64.5 percent (age-adjusted rate). All additional indicator views are based on the new methodology. For combined years 2012 to 2014, there were no significant differences in mammography screening rates between Hispanic and non-Hispanic ethnic groups. Among different races, American Indians had the lowest screening rates and Asians had the highest screening rates; however, there were no significant differences among races. Summit County Local Health District reported significantly higher screening rates than the state (75.7 percent), while three local health districts reported significantly lower screening rates when compared to the state (Central, 56.2 percent; Southeast, 53.2 percent; and TriCounty, 52.5 percent) for combined years 2013-2014. After dividing the health districts into Utah Small Areas the prevalence of mammograms, for combined years 2012-2014, ranged from a high of 78.4 percent in Riverdale to a low of 39.1 percent in Grand/San Juan. In 2014, Utah women 40 to 49 years of age were significantly less likely to have received a mammogram within the past two years than older women (52.7 percent vs 71.7 percent among women 50-64 and 71.4 percent among women 65 and over). In 2014, when looking at the highest level of education completed, college graduates were significantly more likely to have received a mammogram than persons with a high school degree or less (college graduate, 69.4 percent; high school graduate, 63.4 percent; below high school, 54.6 percent). Also in 2014, women in households with an annual income of less than $25,000 were significantly less likely to have had a mammogram in the past two years compared to those in households earning $50,000 or more (52.3 percent vs. 66.7 percent for incomes of $50,000-$75,000 and 71.5 percent for incomes of $75,000 or more).
How Do We Compare With the U.S.?Nationally, the percentage of women aged 40 or older who reported receiving a mammogram in the past two years increased from 55.2 percent in 1989 to 74.9 percent in 2010. Since 1994, the percentage of Utah women aged 40 or older who reported receiving a mammogram has been below the U.S. rate. In 2012, based on new methodology, 64.5 percent of Utah women aged 40 and older had received a mammogram in the last two years compared with 72.3 percent of U.S. women.
What Is Being Done?The Utah Cancer Control Program (UCCP) in the Utah Department of Health (UDOH) distributes free mammography vouchers to women who receive a clinical breast exam at a UCCP sponsored clinic and meet age and income guidelines. In addition, the UDOH initiated the Utah Cancer Action Network (UCAN), a statewide partnership whose goal is to reduce the burden of cancer. The mission of the UCAN is to lower cancer incidence and mortality in Utah through collaborative efforts directed toward cancer prevention and control. As a result of this planning process, objectives and strategies have been developed by community partners regarding the early detection of cervical, testicular, prostate, skin, breast, and colorectal cancers as well as the promotion of physical activity, healthy eating habits, and smoking cessation.
Available ServicesThe Utah Cancer Control Program (UCCP) provides free to low cost clinical breast exams and mammograms to women who meet age and income guidelines. Eligible women with abnormal screening exams are offered diagnostic evaluation by participating providers. In addition, the UCCP provides education about the need for early detection and the availability of screening services, performs outreach to eligible women, uses an annual reminder system, collects outcome data, and disseminates information about breast cancer. As of July 1, 2001, the UCCP is able to refer Utah women in need of treatment for breast and cervical cancers and precancerous lesions for full Medicaid benefits. The women must meet all requirements as outlined in the National Breast and Cervical Cancer Treatment Act.
Health Program InformationThe UDOH Utah Cancer Control Program (UCCP) distributes free mammography vouchers to women who receive a clinical breast exam at a UCCP sponsored clinic and meet age and income guidelines. Although the Affordable Care Act (ACA) mandates coverage of screening mammograms, many women are still uninsured or need financial assistance for diagnostic mammograms and other services.
