How Locum Tenens Oncologists Keep Cancer Care on Track
At 8:15 a.m. on a Monday in rural West Texas, the infusion center is already full. One patient has driven nearly two hours for chemotherapy. Another is starting treatment weeks later than planned after a previous appointment was postponed. The permanent oncologist left the practice months ago, and recruitment is still ongoing.
Today, care continues because a locum tenens oncologist is stepping in.
Across the U.S., scenes like this are becoming increasingly common. Cancer doesn’t wait, and neither should treatment. Yet oncology workforce shortages are forcing delays that can directly affect outcomes. Locum tenens oncologists are quietly filling those gaps—keeping clinics open, schedules moving, and patients on track when coverage is thin.
On World Cancer Day and during cancer advocacy initiatives, conversations often focus on prevention, research, and awareness. But there is another reality shaping patient outcomes every day: timely cancer care depends on having enough oncologists available to deliver it.
The Oncology Workforce Shortage Is Limiting Access to Cancer Care
Demand for cancer care is rising, driven by an aging population and increasing cancer incidence. Yet access to oncology specialists is declining, especially outside major metro areas.
Hematology Advisor reported that in 2024, nearly 16% of the U.S. population lived in rural areas, yet only 7% of oncologists practiced in rural counties. National oncologist density has dropped from 15.9 per 100,000 adults aged 55 and older in 2014 to 14.9 in 2024, tightening access at the very moment demand is accelerating.
Geographic disparities are stark. While 45% of U.S. counties have practicing oncologists, those counties serve 89% of adults aged 55 and older. Seven percent of counties have no oncologists at all—not even in adjacent counties—leaving 11% of older adults without local access to cancer care.
These shortages are not abstract. Research shows that a four-week delay in treatment for certain cancers can increase mortality risk by approximately 10%.
An Aging Oncology Workforce Adds to the Risk
Workforce demographics further complicate the picture. According to a study published in the Journal of Clinical Oncology: Oncology Practice, 33% of oncologists are late-career, while just 27% are early-career. Rural counties are disproportionately served by late-career physicians, with few early-career oncologists choosing rural practice.
Coverage gaps are most pronounced in communities already facing higher cancer mortality, socioeconomic vulnerability, and limited infrastructure. In these settings, losing even one physician—or leaving a role unfilled—can disrupt care for an entire region.
The result is a system where the greatest care gaps exist where timely oncology care can be lifesaving.
Why Continuous Oncology Coverage Is Critical for Patient Outcomes
In oncology, continuity is not optional. Infusion schedules, consults, follow-ups, and treatment planning depend on having a qualified oncologist consistently available.
When staffing gaps occur, the consequences escalate quickly:
- Infusions are delayed or canceled
- New patient consults are pushed back weeks
- Follow-ups and surveillance fall behind
- Remaining oncology teams face heavier workloads and burnout
Even short-term absences—caused by burnout, medical leave, or unfilled positions—can ripple through an entire cancer program, compounding delays and uncertainty for patients navigating already stressful diagnoses.
How Locum Tenens Oncologists Maintain Access to Cancer Care
Locum tenens oncologists play a stabilizing role in cancer care delivery, particularly during periods of transition, unexpected vacancies, or sustained workforce shortages. On average, the U.S. job market posted more than 500 oncology locum jobs per month.
By providing temporary but immediate coverage, locum oncologists help health systems:
- Keep infusion centers and oncology clinics operational
- Prevent treatment delays through consistent physician coverage
- Support permanent oncologists by enabling time off without care disruption
- Expand access in rural and underserved communities where permanent recruitment is difficult
In many regions, locum oncologists make it possible for patients to receive care close to home instead of traveling hours for treatment, which is an important consideration for patients managing both the physical and emotional toll of cancer.
Locum Tenens Oncology Offers Physicians Flexibility Without Burnout
For oncologists, locum tenens work offers more than flexibility.
As workforce shortages intensify, many physicians face growing patient volumes, administrative burden, and demanding call schedules. Locum tenens oncology provides an alternative career path that allows physicians to continue delivering high-impact cancer care while protecting their well-being and work-life balance.
Locum oncologists benefit from:
- Competitive earning potential
- Fewer or no call requirements
- Flexibility to choose when and where to work
- Greater autonomy over workload and career direction
By regaining control of their schedules, physicians can reduce burnout, spend more time with family, pursue interests outside medicine, and sustain long-term careers in oncology.
At the same time, their work directly supports communities facing the greatest access challenges.
Keeping Cancer Care Moving on World Cancer Day and Beyond
This World Cancer Day, it’s worth recognizing the oncologists who step in when coverage is thin and care is at risk. Locum tenens oncologists keep infusion chairs filled, clinics open, and treatment plans on schedule, often in communities with few alternatives.
They prove that sustaining cancer care starts with sustaining the physicians who deliver it.
