The incidence of breast cancer in the United States has been rising steadily, particularly among younger women, despite advances in treatment and a decline in death rates. According to a new report from the American Cancer Society, the incidence of breast cancer has increased by 1% annually from 2012 to 2021. While mortality rates have decreased, this upward trend in diagnoses raises concerns about the future of breast cancer prevention and treatment.

Breast Cancer Death Rates Decline, But New Cases Continue to Rise
The American Cancer Society’s latest report reveals both progress and concern. On the positive side, overall breast cancer mortality has dropped by 44% since 1989, translating to 518,000 fewer deaths. This is due to better treatment and early detection through screenings, which are now recommended for women starting at age 40. However, the incidence of breast cancer continues to rise. Between 2012 and 2021, new cases increased by 1% annually, particularly affecting younger women under 50.
Karen Knudsen, CEO of the American Cancer Society, emphasized the importance of understanding this rise. “We’ve seen breast cancer incidence rise by about 1% year-over-year, with a slightly higher increase among women under 50,” Knudsen said.
Why Is Breast Cancer Increasing in Younger Women?
A separate study published in January echoed similar concerns, showing that breast cancer incidence among women aged 20 to 49 has increased over the past two decades. This rise among younger women mirrors trends seen in other cancers, like colorectal cancer, with diagnoses increasingly occurring at younger ages.
These patterns suggest a need for further investigation into environmental, lifestyle, and genetic risk factors that might be contributing to the rise in breast cancer diagnoses in younger women.

Racial Disparities in Breast Cancer Outcomes Persist
The report also highlights ongoing racial disparities in breast cancer outcomes. Black women are 38% more likely to die from breast cancer than White women, despite being 5% less likely to be diagnosed with the disease. The disparity is particularly severe among younger Black women, who face mortality rates double those of their White counterparts.
Dr. William Dahut, Chief Scientific Officer at the American Cancer Society, pointed out the importance of addressing these disparities. “Black women between the ages of 20 and 29 have a significantly higher risk of dying from breast cancer, and these numbers are concerning.”
Rise of Breast Cancer in Asian American and Pacific Islander Women
The report reveals another striking trend: a sharp rise in breast cancer diagnoses among Asian American and Pacific Islander women, a group that previously had relatively low incidence rates. Between 2012 and 2021, breast cancer diagnoses in this demographic rose by 2.7% annually in women under 50 and by 2.5% in women over 50.
Experts are exploring whether genetic mutations and lifestyle changes are contributing to this increase. Dr. Ruth Carlos, a radiology professor at the University of Michigan, noted that certain gene mutations could place Asian women at a higher risk for breast cancer compared to White women.

Geographic Differences in Breast Cancer Incidence and Mortality
The incidence and mortality rates for breast cancer vary significantly by region. In Nevada, for example, the incidence rate is 113 cases per 100,000 women, while in North Carolina, it rises to 143 cases per 100,000. Mortality rates also fluctuate: Massachusetts reports 15 deaths per 100,000 women, while Mississippi and Washington, D.C., report 23 and 24 deaths per 100,000, respectively.
These geographic disparities are shaped by several factors, including access to healthcare, mammography screening rates, and state policies related to healthcare access, such as Medicaid expansion.

Projected Breast Cancer Cases in 2024
Looking ahead, nearly 311,000 new cases of invasive breast cancer are expected to be diagnosed in the United States in 2024, affecting roughly 1 in 8 women. More than 42,000 women are projected to die from the disease. These numbers underscore the need for continued research into prevention, treatment, and risk factors contributing to the rising incidence of breast cancer.
What Oncologists Are Seeing: Rising Breast Cancer Incidence in Younger Patients
Doctors on the front lines are already noticing this increase. Dr. Carmen Calfa, a medical oncologist at the University of Miami Health System, mentioned that her clinic is seeing more young breast cancer patients than ever before. “The increase in incidence among younger women is alarming. We’ve been seeing more patients in their 20s and 30s than we used to,” Dr. Calfa said.
This trend isn’t exclusive to breast cancer—rising cancer rates in younger people have been observed across other cancer types as well. According to Dr. Calfa, the shared risk factors across these cancers could provide clues as to why more young people are being diagnosed.
Common Risk Factors for Breast Cancer
Several risk factors may be contributing to the rise in breast cancer diagnoses. These include:
- Family history of breast cancer
- Genetic mutations such as BRCA1 and BRCA2
- Increased alcohol consumption
- Physical inactivity
- High-risk lesions found in breast biopsies
How to Lower Your Breast Cancer Risk
Experts recommend several ways to reduce the risk of developing breast cancer. These include maintaining a healthy weight, staying physically active, limiting alcohol consumption, and getting regular screenings. Additionally, breastfeeding and certain medications, such as tamoxifen, can help lower the risk for some women.
“It’s important for both men and women to understand their personal risk factors and advocate for themselves when it comes to prevention and early detection,” Dr. Calfa emphasized.

Call to Action: Understanding Breast Cancer in Younger Women
As the incidence of breast cancer continues to rise, particularly among younger women and racial minorities, researchers are calling for more studies into the environmental, genetic, and lifestyle factors contributing to this trend. The more we understand these contributing factors, the better equipped we will be to curb the rise in breast cancer cases and improve outcomes for those affected.
FAQs
1. Why is breast cancer incidence rising among younger women?
The incidence of breast cancer is increasing among younger women, possibly due to a combination of genetic, lifestyle, and environmental factors. Further research is needed to understand the exact causes.
2. What are the main risk factors for breast cancer?
Key risk factors include family history, genetic mutations like BRCA1 and BRCA2, alcohol consumption, and lifestyle choices, such as physical activity levels.
3. Are there racial disparities in breast cancer outcomes?
Yes, Black women have a 38% higher risk of dying from breast cancer compared to White women, even though they are slightly less likely to be diagnosed with the disease.
4. What can I do to lower my risk of breast cancer?
You can reduce your risk of breast cancer by maintaining a healthy weight, staying active, limiting alcohol intake, breastfeeding, and getting regular screenings.
5. How does early detection help in the fight against breast cancer?
Early detection through screenings like mammograms can help identify breast cancer at an earlier stage, improving treatment outcomes and survival rates.
