20 Questions to Ask Your Oncologist at Your Next Appointment

Oncology appointments are often short, emotionally charged, and packed with information that's hard to absorb in the moment. Many patients leave feeling like they didn't get to ask everything they wanted to — or didn't know what to ask in the first place.

Preparation changes that. Walking into an appointment with a written list of questions is one of the most effective things you can do to advocate for yourself or a loved one.

Here are 20 questions worth considering — organized by topic — along with guidance on how to use them.

1. Can you explain my diagnosis in plain language? Ask your doctor to describe your diagnosis without jargon. If you don't understand something, ask them to explain it again. There are no foolish questions here.

2. What type and stage is my cancer, and what does that mean for my prognosis? Stage and subtype significantly affect treatment options and outcomes. Make sure you understand both.

3. Has my tumor been tested for genetic or molecular markers? Biomarker testing can identify targeted therapies that may be more effective than standard chemotherapy for certain cancers. If testing hasn't been done, ask whether it's appropriate.

4. Are there any additional tests or imaging you recommend before we decide on a treatment plan? Sometimes additional information changes the approach. It's worth asking whether the picture is complete.

5. What are all of my treatment options? Ask for the full range — not just the recommended approach. Understanding your options helps you make an informed decision.

6. What do you recommend, and why? Ask your oncologist to explain the reasoning behind their recommendation, including what they're weighing and what alternatives they considered.

7. What is the goal of this treatment — cure, control, or symptom management? This is one of the most important questions you can ask. The answer shapes everything else.

8. What is the expected timeline for treatment? How long will treatment last? What does the schedule look like week to week?

9. Are there clinical trials I should consider? Clinical trials offer access to cutting-edge treatments and are worth asking about at any stage of diagnosis.

10. What happens if I choose not to pursue treatment, or delay it? Understanding the consequences of inaction helps you make a fully informed decision.

11. What are the most common side effects of this treatment? Ask about both short-term and long-term side effects, and how they're typically managed.

12. How will this treatment affect my daily life? Will you be able to work? Drive? Care for dependents? Travel? Understanding the practical impact matters.

13. What side effects should prompt me to call your office immediately? Know the warning signs that require urgent attention.

14. Are there supportive care services available — nutrition, physical therapy, mental health support? Many cancer centers offer integrative services that can significantly improve quality of life during treatment.

15. Who is the primary point of contact for questions between appointments? Know who to call — and how — when questions or concerns arise outside of scheduled visits.

16. Will you be coordinating with my other doctors? How does that communication work? If you have other specialists involved in your care, make sure your oncologist is in the loop.

17. What records or reports will be shared with my primary care physician? Your PCP should be informed about your cancer treatment, especially for managing other health conditions.

18. Would you support me in getting a second opinion? Any reputable oncologist will support this. If yours doesn't, that's important information.

19. Is there a major cancer center or specialist you would recommend for a second opinion? Your oncologist may have specific recommendations based on your diagnosis.

20. Can you help facilitate the transfer of my records for a second opinion? Getting records transferred promptly can prevent delays in the second opinion process.

Bring a support person. Having a family member or friend present means two sets of ears, and someone to take notes while you focus on the conversation.

Write your questions down in advance. Don't rely on memory in a high-stress appointment. Bring a printed list.

Prioritize. You may not get through all 20 questions in one appointment. Identify your top 5 and make sure those get answered.

Record the conversation. With your doctor's permission, recording the appointment allows you to review it later when you're not in the moment.

Ask for clarification. If you don't understand an answer, say so. "Can you explain that differently?" is always an appropriate response.

Sometimes the challenge isn't knowing what to ask — it's having the bandwidth to prepare, process the answers, and follow up on what you learn. That's where a cancer navigator can help.
