Health Indicator Report of Cancer Screening - Mammography

Breast cancer is the most common cancer among women (excluding non-melanoma skin cancer) and is the second leading cause of cancer death in New Mexican women (after lung cancer). Regular mammograms are the best tests health providers have to screen for breast cancer.

Estimated Percentage of Women Ages 50-74 Years Who Have Had a Mammogram Within the Past Two Years by County, New Mexico: 2012, 2014, 2016


Due to small sample sizes, BRFSS data for 2012, 2014 and 2016 were aggregated in order to provide stable county estimates.

Notes

The breast cancer screening questions are only administered in the BRFSS in even-numbered years. In January 2016, the United States Preventive Services Task Force (USPSTF) updated its previous 2009 recommendations for breast cancer screening; however, the update contained no changes in screening recommendations for average-risk women based on age group. For women ages 40-49 years, mammography screening is not routinely recommended, but women who place a higher value on the potential benefit than the potential harms may choose to begin screening every two years. For women ages 50-74 years, mammography screening is recommended every two years. For women ages 75 years and older, there was insufficient evidence to recommend for or against mammography screening.   Note: The county-level BRFSS data used for this indicator report were weighted to be representative of the New Mexico Health Region populations. Had the data been weighted to be representative of each county population, the results would likely have been different. **The count or rate in certain cells of the table has been suppressed either because 1) the observed number of events is very small and not appropriate for publication, or 2) it could be used to calculate the number in a cell that has been suppressed. For survey queries, percentages calculated from fewer than 50 survey responses are suppressed. Estimates for the following counties have been suppressed due to small numbers: Catron, De Baca, Guadalupe, Harding, Hidalgo, Mora, Torrance and Union.

Data Sources

  • Behavioral Risk Factor Surveillance System Survey Data, U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, together with New Mexico Department of Health, Injury and Behavioral Epidemiology Bureau.

Data Interpretation Issues

Data for this indicator report are from the Behavioral Risk Factor Surveillance System (BRFSS), an ongoing survey of adults regarding their health-related behaviors, health conditions, and preventive services. Data are collected in all 50 states, D.C., and U.S. territories. Responses have been weighted to reflect the New Mexico adult population by age, sex, ethnicity, geographic region, marital status, education level, home ownership and type of phone ownership. The survey is conducted using scientific telephone survey methods for landline and cellular phones (with cellular since 2011). The landline phone portion of the survey excludes adults living in group quarters such as college dormitories, nursing homes, military barracks, and prisons. The cellular phone portion of the survey includes adult students living in college dormitories but excludes other group quarters. Beginning with 2011, the BRFSS updated its surveillance methods by adding in calls to cell phones and changing its weighting methods. These changes improve BRFSS' ability to take into account the increasing proportion of U.S. adults using only cellular telephones as well as to adjust survey data to improve the representativeness of the estimates generated from the survey. Results have been adjusted for the probability of selection of the respondent, and have been weighted to the adult population by age, gender, phone type, detailed race/ethnicity, renter/owner, education, marital status, and geographic area. Lastly and importantly, these changes mean that the data from years prior to 2011 are not directly comparable to data from 2011 and beyond. Please see the [https://ibis.health.state.nm.us/docs/Query/BRFSS/BRFSS_fact_sheet_Aug2012.pdf BRFSS Method Change Factsheet]. The "missing" and "don't know" responses are removed before calculating a percentage.

Definition

Estimated percentage of New Mexican women ages 50-74 years who have had a mammogram in the past two years (i.e., current with breast cancer screening recommendations). A mammogram is an X-ray picture of the breast. Health care providers use a mammogram to look for early signs of breast cancer.

Numerator

Number of New Mexican women ages 50-74 years from the Behavioral Risk Factor Surveillance System (BRFSS) who reported that they have had a mammogram within the past two years.

Denominator

Number of New Mexican women ages 50-74 years from the Behavioral Risk Factor Surveillance System (BRFSS).

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

Other Objectives

New Mexico Cancer Plan 2012-2017 Objectives: By 2017, increase by 15% the proportion of NM women ages 40 and older who have had a mammogram in the past 2 years, from a 2010 baseline of 71% to 81.7%. New Mexico Community Health Status Indicator (CHSI)

How Are We Doing?

The percent of New Mexican women who are current with breast cancer screening recommendations has remained stable for more than a decade.

How Do We Compare With the U.S.?

Comparable rates for the United States for "current" with breast cancer screening are only available for 2014 at this time. In 2014, among women ages 50-74 years, breast cancer screening rates were lower for New Mexico compared to the United States.

What Is Being Done?

The New Mexico Breast and Cervical Cancer Early Detection Program (BCCP) is dedicated to improving access to high-quality, age-appropriate breast cancer screening and diagnostic services for low-income women who are uninsured or under-insured, and helping them access resources for treatment when necessary. To do this, the BCCP supports changes within provider practices and health systems to increase screening opportunities. In addition, data and surveillance systems, such as monitoring screening quality measures, are used to develop more organized, systematic approaches to cancer screening and to improve service delivery. These approaches are supported by the New Mexico Department of Health and are being implemented by many healthcare organizations and health systems throughout New Mexico. Visit the BCCP website at: http://archive.cancernm.org/bcc/index.html

Evidence-based Practices

The BCCP supports New Mexico health care providers and health systems in using evidence-based interventions such as patient reminders, risk assessment tools, reducing structural barriers (e.g., expanding clinic hours, provision of mobile mammography events), provider reminder and recall systems, and provider assessment and feedback on performance. All of these activities have been shown to increase breast cancer screening rates, and are recommended by The Guide to Community Preventive Services, a collection of evidence-based findings of the Community Preventive Services Task Force, established by the U.S. Department of Health and Human Services.

Available Services

The New Mexico Breast and Cervical Cancer Early Detection Program provides free breast cancer screening and diagnostic services to New Mexico women ages 40 years and older who lack health insurance and who live at or below 250% of the federal poverty level. More information can be found online at http://archive.cancernm.org/bcc/index.html or by calling toll-free 1-877-852-2585. Uninsured women in New Mexico should check to see if they qualify for Centennial Care, which is New Mexico's Medicaid program, at: https://nmmedicaid.acs-inc.com/static/index.htm Uninsured women who don't qualify for Centennial Care may be able to purchase a health insurance plan during certain times of the year through the New Mexico Health Insurance Exchange at: http://www.bewellnm.com/

Health Program Information

The most effective strategy for detecting early-stage breast cancer is screening mammography. The resulting earlier treatment may be life-saving, depending on the breast cancer type and quality of care. The United States Preventive Services Task Force (USPSTF) estimates that over a ten-year period, screening 10,000 women ages 60 to 69 years would result in about 21 fewer breast cancer deaths. Over the same ten-year period, there would be about eight breast cancer deaths averted in 10,000 women screened at ages 50-59 years, and about three breast cancer deaths averted in 10,000 women screened at ages 40-49 years. Screening mammography also has risks. In addition to false-positive results and unnecessary biopsies, all women undergoing regular screening mammography are at risk for the diagnosis and treatment of noninvasive and invasive breast cancer that would otherwise not have become a threat to their health, or even apparent, during their lifetime (known as "overdiagnosis"). The USPSTF notes that the best estimates from randomized controlled trials suggest that one in five women diagnosed with breast cancer over approximately ten years will be overdiagnosed. Since we can't currently identify which breast cancers are overdiagnosed, they are all treated, meaning that one in five women diagnosed with breast cancer through screening may be enduring surgery, radiation therapy, and/or chemotherapy that she never would have needed. The BCCP is exploring the best options for providing more balanced and useable information to women about both the potential benefits and harms of breast cancer screening. The intent is to enable women to make well-informed decisions about breast cancer screening that are consistent with their values and priorities.
