Follow-up & surveillance
Can You Refuse — a Follow-Up PET Scan?
You have the right to decline a follow-up PET scan. The question worth sitting with is what declining means for your care — and whether the barrier driving the question has an answer your team can help with.

- Your right to decide — You cannot be compelled to attend a surveillance scan. It is your decision to make.
- The real risk is delayed detection — Most recurrences grow without symptoms. Scans are how they are usually found early.
- Alternatives may exist — Depending on your cancer type, CT, MRI or blood markers may be options. Ask directly.
- Name the barrier — Cost, travel, anxiety — each has a different response. Your team cannot help with what they do not know.

You have the right to decline a follow-up PET scan. Your oncologist cannot compel you. What matters is that you understand what declining means for your care: surveillance scans are how most recurrences are found before symptoms appear, and recurrence found earlier usually leaves more treatment choices open.
At CION, a whole-body PET-CT starts from Rs 10,499 — among the lowest published prices in Hyderabad. Indicative price, as of September 2026.
Declining vs. continuing: what changes for you?
| Declining the scan | Continuing as scheduled | |
|---|---|---|
| Recurrence detection | Relies on symptoms appearing — recurrence may be further advanced when found | Most recurrences are caught at an earlier, more treatable stage |
| Radiation exposure | That scan's dose is avoided | Cumulative dose increases with each scan, though individual doses are within accepted clinical limits |
| Cost for this scan | Not incurred | Each scan has a cost; frequency is set by your cancer type and protocol |
| Scan anxiety | Avoided for now | Can be significant — worth discussing openly; schedule adjustments are sometimes possible |
| Treatment options if cancer returns | May be narrower if recurrence is found at a later stage | Earlier detection generally leaves more treatment options open |
| Your team's role | Notes your decision, discusses alternatives, keeps the door open | Monitors results and acts quickly on any finding |
What does skipping a follow-up scan actually risk?
Surveillance scans exist because many recurrences grow without symptoms until they are at an advanced stage. Finding one early, while you feel well, is the point of the schedule.
Declining does not cause cancer to return. But it removes the earliest window your team has to find it. Whether that matters depends on your cancer type, how far you are into follow-up, and what alternatives your team can offer.
Your oncologist cannot force you to attend. What they can do is explain what the scan is looking for, why the timing matters, and what the plan would be if something were found.

What alternatives can you ask your team about?
Whether an alternative is possible depends on your cancer type. Some cancers can be monitored with CT rather than PET-CT, which uses a lower radiation dose. Others can be followed with MRI, which uses no radiation. A few can be partially tracked with blood tumour markers.
No alternative is as sensitive as PET-CT for every cancer type. Your team will tell you honestly what a different approach would and would not detect.
If cost, travel or anxiety is the barrier, say so directly. Surveillance adjustments are sometimes possible without compromising your care, and your team cannot explore that unless they know what is driving the reluctance.
Questions people work through before deciding
Does declining this scan mean I am giving up on treatment?
Declining one scan is not a treatment decision and does not change your current treatment. It is a surveillance decision — about how closely you are being monitored for signs of recurrence. You remain in your oncologist's care, and the scan schedule can be revisited at any appointment. One missed scan does not permanently change your relationship with your team.
Can I ask for a less frequent schedule rather than stopping altogether?
Yes, and this is often a more productive conversation than a flat refusal. NCCN and ESMO surveillance schedules are built for patient populations, not individuals. Your oncologist has some flexibility, particularly as time passes and your risk of recurrence changes. Ask directly: what is the minimum schedule your team would feel comfortable with, and what would prompt them to recommend more frequent scanning again?
What do I tell my oncologist if I want to stop or reduce scans?
Say exactly what is driving the decision. If cost is the reason, name it — there may be options you are not aware of. If scan anxiety is the reason, name it — support pathways exist. If you have decided after consideration that you do not want more scans, you are entitled to say so. A good oncologist will document your decision, explain what symptoms to watch for, and keep the door open if you change your mind.
Are the radiation doses from repeat PET-CT scans dangerous?
Each PET-CT scan involves ionising radiation, and cumulative dose is a legitimate concern worth raising with your team. NCCN and ESMO surveillance guidelines are designed around the minimum number of scans needed to detect what needs to be detected. Ask your team how many scans you have had and whether lower-radiation alternatives are available for your specific cancer type.
What symptoms should I watch for if I am not being scanned?
Ask your team for a written symptom list specific to your cancer type and treatment history — if you do not have one, request it at your next appointment. Things to report regardless of cancer type include unexplained weight loss, new lumps or swelling, pain that does not resolve, and any new symptom lasting more than two weeks. This is not a substitute for imaging but it tells your team when to investigate between scans.
Did you know?
Anxiety about repeat surveillance scans — sometimes called scanxiety — is recognised by ASCO as a genuine clinical experience that affects many people in long-term follow-up, not a minor inconvenience. Naming it to your team is the first step: it can change how your care is arranged, and sometimes how your schedule is structured.

Common questions
Frequently asked questions
Can my oncologist discharge me from care if I refuse a scan?
No. Your oncologist will note your decision, explain the implications, and usually ask whether something — cost, anxiety, travel — is behind the refusal and whether it can be addressed. You remain their patient. What changes is that they cannot reassure you from imaging they have not seen. The care relationship does not end because you declined a test.
How do I know whether my cancer type specifically needs PET-CT?
Ask directly: is PET-CT the only imaging that will detect what you are looking for, or would CT or MRI be sufficient? For some cancers, PET-CT is the standard because it shows metabolic activity that CT cannot. For others, CT or MRI is equally useful. Your oncologist knows which applies to you, and that answer shapes how significant declining a PET-CT specifically is for your situation.
Will skipping one scan mean I miss my chance to treat a recurrence?
It depends on how quickly your cancer type typically regrows — something your oncologist can tell you. Some cancers grow slowly enough that a delayed scan is unlikely to make a decisive difference. Others grow quickly, and even a few months' delay can change the stage at which a recurrence is found. The most useful question to ask is: what is the realistic cost of a delay of a few months for my specific cancer?
Is declining a surveillance scan the same as declining treatment?
No. Surveillance and active treatment are separate parts of your care. You can continue all treatment and decline surveillance scanning. You can also decline treatment and continue surveillance. They are independent decisions with different consequences. Declining a scan means your team will have less information about what is happening inside your body — it does not change what treatment you are currently receiving.
What if I cannot afford the scan right now?
Tell your team that cost is the reason — do not simply not attend without explaining why. The response to a financial barrier is different from the response to a principled refusal. Your team may know of payment plans, government health schemes, or alternative imaging that costs less and still works for your cancer type. CION can discuss what options are available at your centre.
How long does follow-up scanning usually continue?
Schedules vary by cancer type and are built around NCCN and ESMO guidelines. Scans are typically more frequent in the first years after treatment and less frequent as recurrence risk falls with time. For most cancer types, surveillance does not continue indefinitely — it eventually transitions to annual review or a symptom-led approach. Ask your oncologist where you are on that trajectory and when the schedule is next likely to change.
