What is an oncologist?
An oncologist is a physician specialized in diagnosing and treating cancer.
Depending on the treatment type, they may focus on chemotherapy and medical therapies (medical oncologist), surgical oncology, or radiation therapy; often several oncologists coordinate a single patient's care.
When should I see an oncologist?
- A cancer diagnosis confirmed by biopsy or another test.
- An imaging or lab result suggesting possible cancer.
- A significant family history of cancer, for risk evaluation.
- Follow-up after previous cancer treatment.
- A second opinion on a diagnosis or treatment plan.
What they manage
- Cancer diagnosis and staging
- Chemotherapy and targeted therapies
- Coordination with surgical oncology and radiation therapy
- Follow-up and surveillance after treatment
- Management of symptoms related to cancer or its treatment
What to expect at your first appointment
The oncologist thoroughly reviews your diagnosis, prior tests (biopsies, imaging), and overall health — bring copies of records from your doctor back home if you're traveling for a second opinion.
They'll explain your cancer's type and stage in clear terms, along with available treatment options, their benefits, and expected effects.
It's normal for this first visit to run long and for you to leave with many questions; you can ask them to repeat information or bring someone you trust to the appointment.
