Navigating care
The short answer on finding the right oncologist
If your cancer is rare, has come back, has stopped responding or is molecularly complicated, look for at least one oncologist who engages with your tumor's biology, plans ahead and welcomes your questions. No doctor will have every quality on the list. A few can change a lot. The way to find out is to ask how they think.
What to know about finding the right oncologist
- This is for complicated cases. Standard care works through one treatment at a time. Some situations call for a doctor willing to think beyond that default.
- Prestige isn't the test. A top cancer center does many things well, but it doesn't guarantee the qualities below.
- Listen to their questions. A doctor who asks good questions about your case often matters more than one with quick opinions.
- "I don't know" can be a good answer, especially when it comes with what would change their mind.
- Direction, not perfection. You're looking for someone strong on a few of these, not all of them.
Why does finding the right oncologist matter for a complex cancer?
Most cancer care follows established protocols in sequence: one treatment at a time, moving to the next when one stops working. For many people, that's exactly right. But for cancers that are rare, relapsed, refractory or molecularly complex, Future of Cancer Care Today argues that it helps to have at least one oncologist on your team who is rigorous, curious and flexible enough to think past that default.
Where should you look for an oncologist for a rare or complex cancer?
Top-tier cancer centers standardize their protocols for good reasons. On a complicated case, though, the guide suggests it can help to also have a physician who has worked outside those systems and brings a different kind of thinking. Look at both well-known institutions and doctors with broader experience.
What should you look for in an oncologist for a complex cancer?
They engage with your tumor's biology, not just your diagnosis. They're interested in what your molecular reports say, and in research beyond the summary a testing company provides.
They plan forward. They think about what comes next instead of waiting for the current treatment to fail.
They're open to combining therapies when the clinical picture supports it, rather than only working through them one at a time.
They can reason through incomplete evidence. They can say what is known, what is uncertain and what would change their thinking.
They have some experience beyond standard pathways, such as filing compassionate use requests, prescribing off-label therapies backed by molecular reasoning, or matching patients to trials based on tumor biology.
They stay close to the science, through research, publications or early-phase trials, and it shows up in how they think about your case.
They think across treatments: surgery, radiation, drug therapy, immunotherapy, cell therapy, imaging, monitoring, supportive care and trials.
They welcome outside input. Second opinions and informed questions from you and your family don't make them defensive.
The guide adds one more, which some readers will find surprising: a doctor who is open about using AI to get up to speed, and who assumes you are using it too.
What are the signs of a good or poor fit with an oncologist?
A good fit gives specific answers about your case instead of general reassurance, is honest about what they don't know, explains what data would change a decision and engages with your questions instead of deflecting them.
A poor fit dismisses new ideas without reasoning through them, uses "there's no evidence" to end a conversation rather than inform it, is uncomfortable with outside testing or input, puts off planning until the current treatment fails, and shows little interest in your goals, timing or constraints.
Questions to ask a new oncologist about a complex cancer
- Have you reviewed all of my molecular reports together? Is there anything we should be paying more attention to?
- Is there deeper testing that could help in my case, such as RNA sequencing, drug-response testing or advanced pathology staining?
- If this treatment stops working, how are you thinking about what comes next?
- Are there therapies used for other cancers that might be relevant to my tumor's biology?
- Have you ever pursued compassionate use or expanded access for a patient? Would you, if my situation called for it?
- Would you consider combining treatments if we can manage the side effects?
- Would you use tools like liquid biopsy or MRD testing to track how I'm responding between scans?
- How do you feel about patients bringing in their own research or input from other specialists?
