The short answer
Move for structural reasons: no biomarker testing, no tumor board, low surgical volume, no trials, or a plan you cannot get explained. Test the question with a second opinion first.
The strongest reasons to move are structural, not personal: missing biomarker testing, no multidisciplinary review, low volume for a complex operation, no clinical trial access, or a rare cancer nobody nearby has treated.
A second opinion is the cheap test of whether you need to move at all. Most people who get one end up staying put, better informed.
Communication breakdown is a legitimate reason to change, but try repairing it first — ask for a plan-of-care visit and a named point of contact.
Bad news is not evidence of bad care. Progression on treatment usually reflects the biology of the disease, not a mistake by your oncologist.

The full explanation.
Separate Two Different Decisions
People usually arrive at this question with two things tangled together: "am I getting the right treatment" and "do I like how I'm being treated." They have different answers and different fixes. A second opinion settles the first. A conversation, or a change of oncologist within the same practice, often settles the second.
Work out which one you are actually asking about before you do anything.
Reasons That Justify Moving
These are structural — they describe what a program can and cannot offer, not how anyone made you feel.
- No biomarker or genomic testing. For lung, colorectal, breast, melanoma, and a growing list of others, testing determines first-line treatment. If it has not been done and no one can say why, that is a substantive gap.
- A complex operation at a low-volume hospital. Pancreatic, esophageal, liver, complex gynecologic and sarcoma surgery show the strongest relationship between how often a hospital does the operation and how patients do afterwards. Ask the annual number. A hospital doing a handful a year is a reason to look elsewhere.
- No multidisciplinary review. If nobody can tell you whether your case was discussed by more than one specialist, and there is no tumor board to send it to, decisions are being made in a single lane.
- A rare cancer. Sarcoma, neuroendocrine tumors, cholangiocarcinoma, unknown primary, rare hematologic subtypes. For these, experience is concentrated in a few centers and the difference in familiarity is large.
- No trial access, especially after first-line treatment. If you have progressed and there is nothing on offer but the next standard drug, a center with an open trial portfolio is worth a consultation.
- A plan nobody will explain. You are entitled to know the goal of your treatment — cure, control, or comfort — in plain words. Repeated inability to get that answer is a real problem, not impatience on your part.
Reasons to Pause Before Moving
- Progression or recurrence. Painful, and usually the disease rather than an error. Use the moment to check testing, trials and tumor board review instead.
- One rushed appointment. Clinics run late and oncologists have bad days. Ask for a longer follow-up visit specifically to go through the plan.
- Something you read that contradicts your plan. Bring it in. "I read about X — is that relevant to my situation?" is a fair question and a good doctor will engage with it.
- Distance nostalgia. A famous name three states away that you cannot reach reliably for six months of treatment is not obviously better than a competent program twenty minutes from your house.
Test the Question Before You Act on It
A second opinion is the low-cost way to find out whether you have a treatment problem or a relationship problem. It is standard practice before major cancer surgery, most insurers cover it, and Medicare Part B specifically covers a second opinion for non-emergency surgery — and a third if the first two disagree. Competent oncologists are not offended; many arrange them routinely. Fear of causing offense is the single most common reason people skip a step that could change their treatment.
Most people who get a second opinion end up staying where they are, with a plan they now understand.
The Middle Path Most People Miss
You often do not have to choose between the big center and the local one. A common arrangement: consultation and complex surgery at a high-volume center, chemotherapy and routine follow-up at your local practice, with defined checkpoints back at the center for restaging. Ask both sides directly whether they will work that way. Most will.
If You Decide to Move
Book the new consultation first. Request records, pathology slides and imaging discs before you announce anything. Check network status and expect new prior authorizations. Time the switch between treatment cycles, and never in the middle of a radiation course.

Common questions
How do I tell the difference between a doctor I dislike and a doctor who is wrong?
Separate style from substance. Style is tone, eye contact, how rushed the visit feels — real problems, sometimes fixable. Substance is whether the recommended plan matches what other specialists would recommend for your diagnosis, stage and biomarkers. A second opinion answers the substance question directly and cheaply. If the second opinion matches your current plan, you have learned that the plan is sound and your problem is communication, which is a different fix.
My cancer came back or is progressing. Should I change doctors?
Not on that basis alone. Cancer progressing through treatment is usually the biology of the disease rather than an error. What is worth checking at that moment: whether comprehensive biomarker or genomic testing has been done on current tissue, whether any trials are open for you, and whether your case has been to a tumor board. If the answer to all three is no, that is a reason to seek an opinion at a center that can offer them.
Is it worth moving for a clinical trial?
Sometimes, and it is one of the clearest reasons to travel. Trials are concentrated at academic and NCI-designated centers. Ask your current oncologist which trials you might qualify for, then search NCI's clinical trials database or ClinicalTrials.gov yourself using your diagnosis and biomarkers. Trials often require frequent on-site visits early on, so factor real travel into the decision.
I am on Medicare or Medicaid. Can I still move?
Usually yes, with caveats. Original Medicare lets you see any doctor who accepts Medicare. Medicare Advantage and Medicaid managed care plans have networks — check network status before you commit, and ask about out-of-network exceptions for services not available in network. Medicare Part B also covers a second surgical opinion for non-emergency surgery, and a third if the first two disagree.
