In Colorado, African American women, Latino/Hispanic women, uninsured/underinsured women and women living in rural communities experience the most barriers to care and often impacted by late detection. Both barriers to care and late detection lead to high rates of mortality from breast cancer in these communities.
Screening Mammography Rates
After mammography was shown to be an effective tool to detect breast cancer at early stages of disease progression in the late 1980s, the use of screening mammography in the U.S. quickly increased.
In 1987, 29 percent of women 40 years and older reported having a mammogram within the past two years. By 2000, mammography use increased to 70 percent.**
Since 2000, there has been a slight decline in mammography use for reasons that remain unknown. **

Breast Cancer Incidence
In the 1980s, breast cancer incidence – the volume of breast cancers that were diagnosed – rose greatly (likely due to adoption of screening mammography to detect breast cancers that might not have been detected before), and then leveled off during the 1990s. Since 2004, the incidence of breast cancer has remained stable.*
Washington D.C., Connecticut, and New Hampshire have the highest breast cancer incidence rates. Wyoming has the lowest.**

Breast Cancer Mortality
Breast cancer mortality (death) rate in the U.S. increased slowly from 1975 through the 1980s.*
From 1989-2014 (most recent data available), breast cancer mortality decreased by 38 percent (avoiding about 300,000 deaths).**
This decline in mortality is due to improved breast cancer treatment and early detection.** However, with 40,000 women dying from the disease each year in the U.S., Susan G. Komen doesn’t believe that’s good enough – and is why we have announced an aggressive goal to cut in half the number of breast cancer deaths by 2026.
Washington D.C., Louisiana, and Mississippi have the highest breast cancer mortality rates. Hawaii has the lowest.** Research in Colorado has shown that people diagnosed with breast cancer who live in communities with lower household incomes have lower long-term survivorship rates than those from more affluent communities.

How Breast Cancer Affects Different Groups
Black women have the highest breast cancer mortality overall. American Indian/Alaska Native women have the lowest.
