Distribution of Oncologists Across the United States

Key Factors Driving the Oncologist Shortage

An Aging Population & Workforce

Demographic shifts over the next decade will continue to duel the demand for oncologists. The number of U.S. adults aged 65 and older is expected to double by 2030, with cancer diagnoses among this projected to increase by 67% between 2010 and 2030

The aging population not only increases the demand for oncologists but also contributes to the workforce shortage as a substantial number of practicing oncologists are nearing retirement age. 

Key Factors Driving the Oncologist Shortage - Oncology Workforce Demographics

Strategic workforce planning will be vital in meeting the growing demand for cancer care and mitigating the impact of a retiring workforce.

Trends in Cancer Incidence & Monitoring

Cancer incidence in the U.S. is increasing, driven by a growing number of cases among young adults and the higher risk of cancer associated with an aging population. 2024 marked the first year in history that the U.S. saw over 2 million cancer diagnoses.

In addition, advancements in cancer treatments have improved survival rates, resulting in a growing survivor population requiring ongoing care. Oncologists will continue to face increased demand for follow-up monitoring, long-term side effect management, and recurrence screening while also continuing to treat new diagnoses. 

Geographical Disparities in Cancer Care Access

The oncology workforce is heavily concentrated in a few urban counties, leaving the majority of rural counties in the U.S. without an oncologist. The uneven distribution of oncologists impacts timely diagnosis, survival rates, quality of life, and treatment costs. Addressing the geographical disparity of oncologists is essential to improving outcomes and ensuring equitable access to cancer care for all.

Strategic Strategies for Overcoming the Oncologist Shortage

Expand the use of Advanced Practitioners

The integration of nurse practitioners (NPs) and physician assistants (PAs) in oncology care has grown significantly, particularly in post-treatment cancer care.

Overcoming the Oncologist Shortage - NPs and PAs

NPs and PAs manage follow-ups and outpatient care, allowing oncologists to focus on consultations and treatment planning. By leveraging NPs and PAs in a team-based approach, healthcare leaders can enhance care delivery and help balance oncologists' workloads more effectively.

Leverage Interim Healthcare Staffing

Utilizing qualified, long-term locum tenens can help effectively mitigate the impacts of the oncologist shortage.
