Cancer care in the United States continues to evolve with cutting-edge technology, multidisciplinary teams, and a focus on personalized treatment. While survival rates and research innovation are important benchmarks, the total number of physicians at a cancer center serves as a critical indicator of its capacity, scalability, and capability to offer specialized care.
In this blog, we dive into the top 20 cancer centers in the US by total physician count, providing insights into why this metric matters, how to use it strategically in healthcare outreach, and how platforms like Ampliz can help you connect with these institutions.
Why Physician Count Matters in Cancer Centers
Cancer treatment is rarely handled by a single doctor. It requires a collaborative network of oncologists, radiologists, pathologists, surgeons, palliative care experts, and research specialists. The larger the physician pool, the more specialized and personalized care a facility can offer.
High physician counts also imply:
- Better patient-to-doctor ratios
- Faster access to care
- Increased capacity for clinical trials
- Enhanced research and academic activity
Whether you’re a patient, researcher, or healthcare marketer, knowing which centers house the most physicians can guide critical decisions.
Methodology for Ranking
To determine the top 20 cancer centers by total physicians, we analyzed:
- Publicly available data from hospital and cancer center websites
- Annual physician rosters and hospital reports
- National Cancer Institute (NCI) designation statuses
- Affiliated university medical schools
This list includes both freestanding cancer hospitals and academic medical centers with dedicated cancer institutes.
