The Hidden Crisis of Uterine Cancer
Uterine cancer is the most common gynecologic malignancy in the United States. Its incidence is rising, particularly for aggressive subtypes like serous carcinoma. Black women face a disproportionate burden, dying from uterine cancer at nearly twice the rate of white women. These disparities manifest across the entire patient journey, encompassing delayed diagnoses, limited treatment options, and poorer survivorship outcomes. This reflects a broader failure to address inequities within the healthcare system, exacerbated by systemic racism, socioeconomic barriers, and gaps in research1.
Why This Matters
The disparities in uterine cancer outcomes among Black women extend beyond access to care. Black women are more likely to develop aggressive forms of the disease and to be diagnosed at later stages, largely due to systemic factors such as inadequate screening protocols and delayed detection. Socioeconomic barriers, provider biases, and environmental exposures further compound these challenges. The inequities in uterine cancer care are not only a reflection of healthcare failings but also a stark indicator of broader societal injustices that require urgent attention.
What We Know: The Evidence
Epidemiology
The overall incidence and mortality rates of uterine cancer are steadily increasing. While all populations are affected, Black women are disproportionately impacted. They are often diagnosed at later stages and have poorer survival rates compared to white women, even when receiving comparable treatments. Factors such as rural residency, lower income, and limited education contribute to delays in diagnosis and worse outcomes2.
Risk Factors
Several factors contribute to the higher risk of uterine cancer among Black women. Obesity, diabetes, and hypertension—conditions more prevalent in Black and Hispanic populations—are strongly associated with uterine cancer. Additionally, reproductive factors such as parity, age at childbirth, and hormonal therapy use vary by racial group, influencing risk profiles. Furthermore, underdiagnosis of genetic conditions like Lynch syndrome and restricted access to genetic counseling exacerbate disparities in prevention and early detection.
Environmental and Geographic Factors
Environmental toxins, particularly in areas with high levels of industrial pollution, are suspected contributors to aggressive subtypes of uterine cancer. Rural regions face additional challenges, including limited access to specialized care, which can delay diagnosis and treatment. These geographic and environmental disparities underline the complex interplay of systemic inequities in healthcare 3.
The Problem in Care Delivery
Barriers to Diagnosis
Uterine cancer lacks standardized screening protocols, leading to late detection in many cases. Black women often face additional diagnostic delays, influenced by implicit biases and systemic racism. Fibroids, which are more common in Black women, can obscure early signs of malignancy. Research highlights how fibroids distort the visibility of the endometrium on transvaginal ultrasounds (TVUS), compromising the accuracy of endometrial thickness (ET) measurements. For instance, a threshold of ≥4 mm for biopsy recommended by the American College of Obstetrics and Gynecology (ACOG) has been shown to miss nearly half of endometrial cancer cases in Black women. These gaps necessitate more tailored and inclusive diagnostic approaches.
Treatment Gaps
Black women are less likely to receive advanced surgical interventions such as minimally invasive procedures or adjuvant therapies like radiation and chemotherapy. Their participation in clinical trials remains disproportionately low, limiting access to novel treatments. Survivorship care is equally inequitable, with inconsistent follow-up care and management of comorbidities contributing to poorer long-term outcomes.
Trust and Communication Failures
Healthcare guidelines are often derived from studies involving predominantly white populations, leaving Black women underserved by “best practices” that fail to address their unique needs. Critical tools like genetic testing and personalized medicine remain inaccessible to many women of color due to systemic biases and financial barriers. The lack of transparency about these limitations erodes trust between providers and patients, further worsening health outcomes.
The Call for Change
Policy and Advocacy
Systemic change begins with policy reform. Expanding Medicaid and advocating for equitable healthcare policies can close the coverage gap for underserved populations. Addressing implicit bias through healthcare provider training and systemic reforms is equally essential to ensure fair treatment and decision-making.
Research and Innovation
Greater diversity in clinical trials is crucial to understanding and addressing disparities. Lessons from the TAILORx trial in breast cancer, which demonstrated the utility of genomic testing in guiding treatment decisions, could inform similar approaches in uterine cancer research. Additionally, studies exploring environmental exposures and their links to aggressive subtypes can shed light on underlying risk factors. Diagnostic and treatment guidelines must be updated to reflect the needs of diverse populations, ensuring inclusivity and accuracy.
Community Engagement
Partnerships with local organizations can drive culturally sensitive education and support programs. Raising awareness of uterine cancer warning signs, such as postmenopausal bleeding, irregular bleeding before menopause, pelvic pain, and unusual vaginal discharge, is vital to early detection. Empowering communities through education and outreach can significantly improve outcomes.
Healthcare System Improvements
Cultural competence training for healthcare providers can address language and cultural barriers that hinder effective communication. Implementing patient navigation programs can assist underserved populations in navigating complex healthcare systems, ensuring timely access to care.
Breaking the Silence
Postmenopausal bleeding, a critical warning sign of endometrial cancer, is too often dismissed or ignored. Black women face greater diagnostic delays, frequently resulting in advanced-stage diagnoses. This is a moral and ethical failure, underscoring the urgency of addressing disparities. Institutions like the Fred Hutchinson Cancer Center and initiatives like the SISTER Study aim to tackle these inequities, but progress remains slow.
A Personal Perspective
As a Black OB-GYN physician-scientist, I have witnessed the devastating impact of these disparities firsthand. During my GYN Oncology fellowship, systemic racism, gatekeeping, and flawed guidelines repeatedly failed Black women. The fact that only 1–3% of gynecologic oncologists in the U.S. are Black is a stark indicator of systemic barriers to equitable care4. Representation is not just about inclusion—it’s about survival.
What You Can Do
Seek immediate care if you experience postmenopausal bleeding. Advocate for yourself and demand a thorough evaluation.
Raise awareness by sharing knowledge about uterine cancer warning signs and disparities in outcomes.
Support research initiatives that prioritize equity in uterine cancer care.
Hold healthcare systems, policymakers, and researchers accountable for addressing these inequities.
The Bottom Line
Uterine cancer disparities are a stark reflection of broader societal inequities. Addressing these disparities requires systemic change, driven by research, policy reform, and community engagement. By investing in equity-driven initiatives, we can work toward a future where all women receive the care they deserve. Together, we can fight for better outcomes for all women.
