October is Breast Cancer Awareness Month
Breast cancer awareness remains a cornerstone of public health efforts worldwide, as early detection and informed prevention strategies can markedly improve outcomes. While breast cancer most commonly affects women, it is not confined by gender, geography, or socioeconomic status. Understanding its epidemiology, who gets it, when, and under what conditions—can sharpen awareness campaigns and guide equitable access to screening, diagnosis, and care.
At its core, breast cancer is the most commonly diagnosed cancer among women in the United States (excluding skin cancers). It accounts for roughly 30 percent of all new female cancer diagnoses. Over the course of a lifetime, about 1 in 8 U.S. women (≈13 percent) will receive a diagnosis of breast cancer.
Age and Breast Cancer: When Risk Rises
Age is one of the single strongest risk factors for breast cancer. Among women under age 40, breast cancer is relatively rare: about 4 percent of invasive cases in the U.S. occur in women younger than 40. After age 40, incidence begins climbing more steeply, and the highest rates of diagnosis occur in women over age 70. The median age at diagnosis in U.S. women is 63.
However, younger-onset breast cancer is not negligible: in 2022, more than 27,000 new breast cancer cases in U.S. women occurred in those younger than 45. Over the past two decades, incidence among younger women (under 45) has been rising, at an average annual increase of 0.7 percent overall (and 1.1 percent per year more recently) from 2001 to 2022. Some studies show rising trends in subtypes like estrogen-receptor–positive cancers among women aged 20 to 49.
Because younger women more often have denser breast tissue (which can obscure mammographic detection), standard screening approaches are less effective in that group. In fact, no widely recommended, population-level breast cancer screening exists under age 40. In younger women, many detect changes via self-examination or symptoms (e.g., a lump), rather than through routine imaging.
Demographic and Racial/Ethnic Disparities
Breast cancer incidence and outcomes differ across racial and ethnic groups, shaped by a mix of biology, access to care, socioeconomic status, and social determinants of health.
- In the U.S., non-Hispanic White and non-Hispanic Black women have historically had the highest incidence rates
- However, Black women experience disproportionately poorer outcomes. They have higher mortality rates from breast cancer compared to White women, even though their incidence is slightly lower.
- Among women younger than 45, Black women have among the highest incidence and death rates and tend to be diagnosed at more advanced stages.
- Additionally, tumor subtypes differ: triple-negative breast cancer (which lacks estrogen, progesterone, and HER2 receptors) is more common in Black women and often has a more aggressive course.
- Among other groups, Hispanic and Asian/Pacific Islander women tend to have lower incidence rates, though trends in some subtypes are rising more sharply in recent years.
- American Indian/Alaska Native women currently have among the lowest incidence rates, though disparities in mortality persist.
These racial and ethnic differences reflect factors such as disparities in screening and access, delays in diagnosis, variations in tumor biology, comorbidities, and differences in treatment.
Why Awareness Matters
The central role of awareness lies in promoting early detection, screening uptake, risk-reducing behaviors, and advocacy for equitable care.
- Early detection saves lives. When breast cancer is caught in its localized stage, the 5-year survival rate is very high.
- Awareness encourages women (and men) to engage with screening where appropriate (e.g. mammography) and to report changes (lumps, nipple discharge, skin changes).
- Knowledge of risk factors—such as family history, BRCA gene mutations, hormone replacement therapy, obesity, alcohol intake, late age at first childbirth, and lack of breastfeeding—empowers individuals and clinicians to tailor surveillance.
- Awareness efforts also help reduce stigma, improve education about lower-risk groups (such as younger women or males), and promote equal access to diagnostics and treatment across demographic strata.
Key Take-Home Messages
- All ages matter. While breast cancer risk rises with age, younger women under 45 are increasingly affected, and their cancers often behave more aggressively.
- Disparities persist. Black women face higher mortality, later-stage diagnoses, and more aggressive subtypes; addressing these requires systemic and community-level interventions.
- Screening has limits. Standard mammography is less sensitive in younger women due to denser breast tissue, making awareness and symptom vigilance critical.
- Prevention and advocacy. Lifestyle modifications, genetic counseling, and health equity advocacy all matter as complements to clinical screening and treatment.
In sum, breast cancer awareness is not just a month-long campaign—it is a sustained call to action to understand who is at risk, why disparities exist, and how timely detection and care can shift outcomes for all populations.

Postscript - I have lived in TTCA for over 50 years and am a member of the Healthy Aging Committee of the TTV. I have personal experience with breast cancer diagnosis, surgery, chemotherapy, radiation therapy and living as a survivor of breast cancer. Should you want to communicate with me about a diagnosis you had or my experiences I am willing to do so.
