´óÏótv researchers report and explain statistics about breast cancer in a new article in CA: A Cancer Journal for Clinicians and in Breast Cancer Facts & Figures 2022-2024.

The effect of weight and fertility rates seem to be limited to an increased risk of hormone receptor-positive breast cancer (HR+)¡ªthe most common type of breast cancer and the largest driver of increasing incidence rates. HR+ tumors are more likely to be detected early through mammography compared to HR- tumors, and they have higher survival.

Most new breast cancer?cases are diagnosed at a localized stage, meaning they have not spread outside of the breast. These early-stage cancers are most often found during breast cancer screening and typically have a high rate of survival because treatment is more effective at this stage.

Black women still have a 4% lower incidence rate of breast cancer than White women but a 40% higher breast cancer death rate.

In this graphic, the breast cancer incidence rate (light pink bars) is highest in?White women and lowest in?Hispanic women. The breast cancer death-rate (dark pink bars) is highest in Black women, followed by American Indian/Alaska Native (AIAN) women, and lowest in Asian/Pacific Islander women. It's notable that Black and AIAN women?both have a higher death rate than White women even though they both have a lower incidence rate for breast cancer than White women.

Breast cancer is the second leading cause of cancer death after lung cancer in women in the US overall, but it¡¯s the leading cause of cancer death in Black and Hispanic women.

During 2016 through 2020, the breast cancer incidence rate was higher in Black women compared to White women in only 4 states: Alabama, Louisiana, Mississippi, and Virginia. In contrast, the breast cancer death rate was higher for Black women than White women in every state except Washington.

¡°Geographical disparities in breast cancer incidence and mortality are due to the differences in the prevalence of risk factors and access to screening and treatment. All of these are influenced by a woman¡¯s socioeconomic status and her distance to medical services, as well as government policies in the state where she lives, such as whether it expanded Medicaid.¡±??¡ªRebecca Siegel, MPH

Overall, the pace of the reduction in female breast cancer?death rates is slower than it was during the 1990s and 2000s. Still, the 43% overall decline in mortality translates to 460,000 deaths avoided between 1989 and 2020. This decline is attributed to earlier detection through breast cancer screening?and increased awareness of the disease as well as improvements in treatment.

The racial disparity in deaths from breast cancer has remained at 40% or higher for a decade.

• Black women younger than age 50 had a death rate that was twice as high as White women that age. Plus, Black women are more likely than White women to die of breast cancer at any age.
• AIAN women were 17% less likely to be diagnosed with breast cancer than White women but 4% more likely to die from the disease.

Part of the reason the breast cancer death rate is not dropping as fast as it has in previous years is because screening rates aren¡¯t increasing and too few women are receiving timely and high-quality treatment after they¡¯re diagnosed with breast cancer.

The study authors point out that ¡°progress against breast cancer mortality could be accelerated by mitigating racial disparities through increased access to high-quality screening and treatment via nationwide Medicaid expansion and partnerships between community stakeholders, advocacy organizations, and health systems.¡±

¡°Coordinated and concerted efforts by policy makers, healthcare systems, and providers are needed to provide optimal breast cancer care to all populations and reduce breast health disparity and accelerate progress against the disease. These efforts include expansion of Medicaid in the 12 non-expansion states and increased investment for new early detection methods and treatments.¡±¡ªAhmedin Jemal, DVM, PhD, ´óÏótv senior vice president of Surveillance & Health Equity Science

Black women have the lowest survival for all subtypes of breast cancer.?

In this graphic, the bars show the percentage of women who are still alive 5 years after a cancer diagnosis based on the cancer¡¯s stage when they were diagnosed (listed along the bottom) and their ethnicity (shown by color).?At each stage, Black women, who are represented by the light pink bars, have the lowest survival.?Black women who develop breast cancer are less likely than any other race to be alive 5 years after their diagnosis, regardless of when their cancer¡¯s when discovered or what type it is.

On January 1, 2022, more than 4 million women were living in the US with a history of invasive breast cancer. Some of them were cancer-free, while others still had evidence of cancer and may have been undergoing treatment.

• Black women have the lowest 5-year relative breast cancer survival rate compared to all other racial/ethnic groups for every stage of diagnosis and every breast cancer subtype.
  
• The largest disparities in 5-year relative survival are for regional and distant stage breast cancer. Only 78% of Black women are living at least 5 years after their diagnosis of regional stage breast cancer compared to 88% of White women. For distant stage, the gap is slightly larger?¨C?21% versus 32%
• There is a 6% to 8% gap in 5-year survival between Black and White women for every breast cancer subtype.

Up to about 30% of breast cancers may be preventable with changes in lifestyle.

About 30% of breast cancer diagnoses are linked to risk factors that women may be able to change¡ªsuch as excess body weight, physical inactivity, and alcohol intake.

Women can help lower their risk for developing breast cancer by being active, maintaining a healthy body weight, and limiting alcohol. They can also help lower their risk of death from breast cancer by talking with their doctor about how often to get a mammogram, sticking with that schedule, and promptly following up on any abnormal results. Following American Cancer Society guidelines for breast cancer screening can help women find breast cancer earlier, when treatments are more likely to be effective.

The advocate affiliate of the ´óÏótv, the American Cancer Society Cancer Action Network (´óÏótv CAN) continues to make efforts to close this persistent gap in screening.

¡°Lawmakers can and must do?more to address the unequal burden of breast cancer among Black women, including increasing funding for the National Breast and Cervical Cancer Early Detection Program (NBCCEDP), a program jointly funded by federal and state governments that helps improve access to lifesaving screenings for these cancers.¡±?¡ªLisa A.
