Questions to ask your oncologist

A visit-prep list for the oncology room: diagnosis, options, side effects, who to call — so you do not blank when the clock is short.

This is not clinical evidence and not medical advice. It does not replace your care team. Discuss anything here with your clinician before you act on it. Product questions are on the FAQ.

How do I prep a question list so I do not blank mid-visit?

This is not clinical evidence and not medical advice. It does not replace your care team. Discuss anything here with your clinician before you act on it. Write the list before you sit down. Portal pings and waiting-room noise make it easy to forget what mattered at 2 a.m. Put the three questions you cannot leave without first — NCI says ask your most important ones early in case time runs out. Add your own; skip what does not fit. If the list is long, ask the desk whether a longer slot is possible.

What should I ask so I leave clear on the diagnosis and stage?

Ask them to write down the exact name of the cancer and the stage. Stage is how large it is and whether it has spread. NCI’s diagnosis list also covers: Has it spread? How serious is it? Repeat the answer in your own words before you leave so you know you heard it.

What more tests might come up before treatment starts?

Ask: Will I need more tests before treatment begins — which ones, and when? Who explains the results? NCI and AHRQ both put this on the post-diagnosis list. If imaging or pathology is already in your file, say so and ask whether anything is still missing.

What should I ask about treatment goals and options?

Ask what treatments exist for your type and stage, the benefits and risks of each, which they recommend and why, when you would start, and how you will know it is working. Ask what happens day to day — where treatment is given, how long sessions take, whether you should plan to rest or work. You can say you need more time before choosing.

What should I ask about side effects and when to call?

Ask which side effects are common during and between sessions, which ones mean call right away, whether any may last, and how to prevent or treat them. Ask whether treatment could affect fertility or appetite. Tell them every medicine, vitamin, herb, and supplement you take — some can change how cancer treatment works.

Should I ask whether a clinical trial fits me?

Yes — it is a normal visit question. NCI’s treatment list includes: Would a clinical trial be right for me, and how do I find studies for my type and stage? If they offer one, ask purpose, how it compares with standard care, risks and benefits, visits, and costs. Keep the deep dive for the study team and consent form.

Is it reasonable to ask about a second opinion in this visit?

Yes. NCI’s diagnosis and treatment question lists include asking your doctor to help you find another opinion on the plan. You can ask in the same appointment where you clarify options. This piece is about asking — not the full how-to of arranging a second opinion.

Should I bring someone with me?

If you can, yes. A family member or friend can listen, take notes, and ask what you forget under pressure. NCI and MedlinePlus both recommend it. If no one can come, ask whether the oncologist will speak with someone you trust by phone.

Can I take notes or record the visit if the clinic allows it?

Take notes, or ask a companion to. Many people cannot remember the visit cleanly afterward. Ask before you record — AHRQ and NCI both say get permission first. You can also ask for a written copy of the plan and whether you can read clinic notes in the patient portal.

What should I walk in with, and who do I call after?

Walk in with a full medicines list (prescriptions, over-the-counter, vitamins, supplements), your written questions, and copies of recent imaging and pathology if you have them. Before you leave, get a name and number for follow-up questions, written instructions, and the best way to reach the office — portal, phone, or nurse line — if something is unclear at home.
