Breast Cancer Statistics, 2022

Area of Science:

• Oncology
• Epidemiology
• Public Health

Background:

• Breast cancer remains a significant public health concern in the United States.
• Trends in incidence, mortality, and survival rates are crucial for understanding the disease burden.
• Racial and ethnic disparities in breast cancer outcomes are a persistent challenge.

Purpose of the Study:

• To provide an updated analysis of female breast cancer statistics in the U.S.
• To examine trends in incidence, mortality, survival, and screening.
• To highlight and analyze racial disparities in breast cancer outcomes.

Main Methods:

• Utilized population-based data for incidence, mortality, survival, and mammography screening.
• Analyzed trends over multiple decades, with a focus on recent data (2010-2020).
• Compared outcomes across different racial and ethnic groups, including Black and White women.

Main Results:

• Breast cancer incidence has increased by 0.5% annually (2010-2019), driven by localized and hormone receptor-positive disease.
• Mortality rates have declined by 43% since 1989, but at a slower pace recently (1.3% annually, 2011-2020).
• Significant racial disparities persist: Black women have higher mortality rates (40% higher overall) and lower survival rates across most subtypes and stages, especially younger women and those with HR+/HER2- or Stage III disease.

Conclusions:

• While overall breast cancer mortality is declining, progress is uneven across racial groups.
• Racial disparities in breast cancer outcomes, particularly for Black women, require urgent attention.
• Accelerating progress necessitates addressing these disparities through enhanced access to screening and treatment, potentially via Medicaid expansion and community partnerships.
