Targeting Oncologists in the US

Oncologists are one of the highest-value physician audiences in all of medicine, and among the harder to reach. There are about 14,500 medical and hematology Oncologists in the US, a workforce that is not keeping pace with rising cancer: more than 2 million Americans are diagnosed each year and new cases are projected to climb by more than half by 2050. Our HCP Targeting is audience-based, not Contextual, so we reach the Oncologist as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That is broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

Our HCP Targeting (including this Oncologist Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Oncologist Audience

There are about 14,500 medical and hematology Oncologists in the US, and the workforce is stretched thin against a rising tide of cancer. Demand is projected to grow far faster than supply, 38 states have fewer Oncologists per capita than they did a decade ago, and more than 2 million Americans are diagnosed with cancer every year. That scarcity, set against soaring need, makes Oncologists one of the highest-value and highest-cost audiences in medicine for Pharmaceutical, Medical Device and Healthcare Technology advertisers. They manage the full breadth of cancer, from Breast, Lung, Colorectal and Prostate cancers to Blood cancers like Leukemia, Lymphoma and Myeloma, and everything in between.

Oncology is also a deeply subspecialized field. Medical Oncology, Hematology-Oncology, Surgical Oncology, Radiation Oncology, Gynecologic Oncology and Pediatric Oncology each function as their own sub-audience, often organized further by tumor type, each with its own drugs, devices and buying decisions. For scale, the American Society of Clinical Oncology (ASCO) represents more than 50,000 members worldwide.

Oncologists work across more settings than most people realize. You will find them in Hospital Cancer Centers and NCI-designated Comprehensive Cancer Centers, in community Oncology practices, in Infusion Centers, in Academic Medical Centers, in Radiation Oncology facilities, and increasingly through Telehealth for follow-up care. Where an Oncologist practices shapes their formularies, their pathways and the products they reach for, so the setting matters as much as the specialty.

Why Advertise to Oncologists

Oncologists sit on top of the single largest and fastest-growing drug market in all of medicine. On the drug side they choose and manage Immunotherapies and Checkpoint Inhibitors, Targeted Therapies and Kinase Inhibitors, traditional Chemotherapy, Antibody-Drug Conjugates, CAR-T and Cell Therapies, Hormonal Therapies, and the Supportive Care drugs that go with them, from Antiemetics to Growth Factors. On the device and technology side they drive demand for Radiation Oncology systems, Infusion technology, Genomic and Companion Diagnostic testing, and the Clinical Pathways and decision-support tools used across cancer care.

Their influence reaches well beyond a single prescription. Oncologists sit on the Pharmacy and Therapeutics committees that decide which high-cost therapies a health system will stock, set the Clinical Pathways that standardize treatment, and lead the Clinical Trials that bring new drugs to market. Because oncology therapies are among the most expensive and most closely managed in medicine, winning the Oncologist has a direct hand in what gets prescribed, reimbursed and bought across the highest-value category in pharma.

Training and education are a market of their own. Oncologists complete an Internal Medicine residency followed by a Hematology and Medical Oncology fellowship, are board-certified through the American Board of Internal Medicine, and many focus further by tumor type or discipline, all with intensive ongoing CME as therapies change fast. Oncology also runs the busiest congress calendar in medicine, led by the ASCO Annual Meeting, the ASH Annual Meeting for blood cancers, ESMO and the San Antonio Breast Cancer Symposium among many others. Together, that makes them a high-value audience for Pharmaceutical, Medical Device and Medical Education advertisers, as well as the medical conferences and congresses working to drive attendance.

Take an “Always On” Strategy for Targeting Oncologists

Oncologists Targeting - Comforting PatientOncologists are a small, in-demand audience carrying heavy caseloads, and they are some of the busiest people in medicine: booked out for weeks and moving between clinic, infusion, tumor boards and research. You can rarely predict when one is online, whether it is between patients, after a full clinic day or on a weekend.

That is why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Oncologists whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you are already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Oncologists across the whole day: on their phone between patients, through a podcast in the car, on the office desktop between cases, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.

Frequently Asked Questions (FAQs)

An Oncologist is a physician who specializes in diagnosing and treating cancer. Medical Oncologists manage cancer with drug therapies like Chemotherapy, Immunotherapy and Targeted Therapy, while Surgical and Radiation Oncologists treat it with surgery and radiation. Many subspecialize by tumor type or in Hematology-Oncology for blood cancers.

There are about 14,500 medical and hematology Oncologists in the US, and the workforce is not keeping pace with demand. Cancer cases are rising, 38 states have fewer Oncologists per capita than a decade ago, and a shortage is projected to widen, which makes Oncologists a high-value and hard-to-reach audience.

Oncology spans several subspecialties. Medical Oncology treats cancer with drugs, Hematology-Oncology focuses on blood cancers, Surgical Oncology removes tumors, and Radiation Oncology uses radiation therapy. There are also Gynecologic and Pediatric Oncologists, and many Oncologists focus further by tumor type such as Breast, Lung or GI cancer.

Oncologists treat the full range of cancers, including Breast, Lung, Colorectal and Prostate cancers, Melanoma, and Blood cancers like Leukemia, Lymphoma and Myeloma. Care runs from diagnosis and staging through Chemotherapy, Immunotherapy, Targeted Therapy, Radiation and surgery, to supportive care and survivorship.
