Beyond prostate cancer
PSMA PET Scan for — Cancers Beyond Prostate
PSMA PET is used routinely in prostate cancer. In kidney, thyroid and a handful of other cancers, it is being studied — not because the scan was repurposed, but because the biology turns out to be connected. Here is what the research shows and what it means if your referral is for a different cancer.

- Established in prostate cancer only — PSMA PET is approved and in routine use for prostate cancer. All non-prostate uses are investigational.
- The biology explains the interest — Many solid tumours grow new blood vessels that carry the PSMA protein on their surface — the same target the scan detects.
- Research is active but early — Kidney, thyroid and brain cancers are among those being studied, but none are standard practice in India yet.
- A clear referral reason matters — If you have been referred for PSMA PET and do not have prostate cancer, ask your oncologist what specific question the scan is intended to answer.

PSMA PET is approved and in routine use for prostate cancer only. In kidney, thyroid, brain and certain other cancers it is being studied, because the PSMA protein appears on blood vessels that feed many solid tumours. These uses are investigational and are not in NCCN or ASCO standard-care guidelines for non-prostate cancers in India.
A whole-body PET-CT at CION costs from Rs 10,499 — among the lowest published prices in Hyderabad. Indicative price, as of September 2026.
Why does a prostate scan show up in research for other cancers?
PSMA stands for prostate-specific membrane antigen, but the name is slightly misleading. The protein is abundant on prostate cancer cells — which is why the scan was developed — but it also appears on the lining of new blood vessels that many solid tumours grow to feed themselves.
Researchers noticed that PSMA scans sometimes showed activity in patients with kidney, thyroid, brain and liver tumours, even when the prostate was uninvolved. That observation is driving current research into whether the scan adds useful information in those cancers.
It does not yet mean the scan is ready for routine use outside prostate cancer.
What do the terms on your referral actually mean?
- PSMA expression
- The degree to which a tumour or its blood vessels carry the PSMA protein. High expression makes the scan light up. In non-prostate cancers, expression is variable and less predictable than in prostate cancer.
- Neovasculature
- New blood vessels a tumour builds to supply itself with oxygen and nutrients. Many of these vessel walls express PSMA — which is why non-prostate tumours sometimes appear on the scan.
- Investigational use
- A use being studied in research or clinical trials that has not yet been approved or included in standard treatment guidelines. It does not mean the scan is experimental in the general sense — it means the evidence base is still being built.
- Off-label
- A scan or treatment ordered for a purpose outside its approved indication. Your oncologist may order PSMA PET for a non-prostate cancer if they believe it will provide information no other available scan can.
- Theranostics
- Using the same molecular target — PSMA here — both to image a tumour and to deliver targeted treatment. PSMA theranostics is established for prostate cancer. For other cancers it is at an early research stage.

What happens at a PSMA PET scan when the cancer is not prostate?
Your oncologist documents the reason
The referral needs to state the clinical indication clearly. Partner imaging centres confirm this before scheduling.
Tracer availability is checked at booking
Gallium-68 PSMA tracer has a short shelf life and is produced in batches. Availability is confirmed at the time of booking, not assumed from the appointment date.
You attend as a day visit
The scan takes two to three hours in total — tracer injection, a waiting period while it circulates, then the PET-CT scan itself. No hospital admission is needed.
The scan is reported in clinical context
A nuclear medicine physician reads the images and notes any areas of PSMA uptake, commenting on whether they are consistent with your known cancer.
Your oncologist decides what follows
A finding on PSMA PET in a non-prostate cancer does not automatically change your treatment. Your oncologist interprets the result against the full clinical picture before deciding on any next step.
Which cancers are being studied with PSMA PET?
Kidney cancer — specifically clear cell renal cell carcinoma — has been one of the more studied non-prostate uses. PSMA expression on its tumour blood vessels is relatively consistent, and early studies show the scan can detect lesions. This is not yet standard practice and does not appear in NCCN or ESMO guidelines for kidney cancer.
Thyroid cancer has been looked at, particularly in cases where radioiodine imaging gives limited information. The evidence is early, and no guideline body currently recommends it as routine.
Brain tumours, including glioblastoma, and some breast and liver cancers have shown PSMA expression in research settings. In every case, the science is at a stage where it might inform a specialist's decision — not a stage where it has replaced established imaging.
We do not yet know which patients with non-prostate cancers benefit most from PSMA PET. That is the honest state of the evidence today.
What should you ask before booking a PSMA PET for a non-prostate cancer?
- Ask your oncologist to explain why PSMA PET specifically is recommended for your cancer type, rather than a more established scan.
- Confirm what clinical question the scan is intended to answer — staging, recurrence detection, treatment selection — and how the result will be used.
- Ask what will change in your treatment plan if the scan is positive, and what will change if it is negative.
- Check whether the cost will be covered, or whether you are paying out of pocket for an investigational indication.
- Confirm tracer availability and your scan date together at the time of booking — do not assume one follows from the other.
- If you would like a second opinion on whether this scan is appropriate for your situation, ask your team to arrange one before you go ahead.
Book a PET-CT at CION from Rs 10,499 — among the lowest published prices in Hyderabad — with an oncologist-reviewed report and a free Rs 950 consultation, across 4 partner centres. Indicative price, as of September 2026.

Common questions
Frequently asked questions
Can PSMA PET be used to diagnose kidney cancer?
Not as a standard test. Kidney cancer is diagnosed and staged with contrast CT, MRI or biopsy. PSMA PET for kidney cancer is being studied because clear cell renal cell carcinoma expresses the PSMA protein on its blood vessel lining, and early studies show the scan can detect lesions. NCCN and ESMO guidelines do not currently recommend it as part of the standard kidney cancer workup. Your oncologist may refer you if there is a specific clinical question it could answer that another scan cannot.
My doctor suggested PSMA PET for my thyroid cancer. Is this normal?
It is uncommon but not without basis. Early research has examined PSMA PET in thyroid cancer, particularly in cases where radioiodine imaging gives limited information. If your oncologist has suggested it, they are likely looking for information that another scan could not provide. Ask specifically what clinical question the scan is intended to answer and what they will do with the result — that answer will help you decide whether it makes sense for your situation.
If my tumour shows PSMA uptake, does that mean PSMA therapy could help me?
Not automatically, and this is an important point. PSMA-targeted treatment — lutetium PSMA — is currently approved for prostate cancer only. Even if a kidney or other tumour shows PSMA uptake on imaging, that does not mean the therapy is available or appropriate for you. Research into PSMA theranostics in non-prostate cancers is at an early stage, and access outside a clinical trial is very limited. A positive scan result is not itself a treatment pathway — your oncologist would explain what options, if any, follow from it.
Will CION do a PSMA PET scan for a cancer other than prostate?
PSMA PET scans are coordinated through CION's partner imaging centres and are established for prostate cancer, at an indicative cost of ₹23,999. For a non-prostate indication, a clear clinical referral and justification would need to be in place, and tracer availability is confirmed at the time of booking. Speak to your oncologist at CION about whether the scan is appropriate for your specific diagnosis before making a booking.
How is PSMA PET different from a regular FDG PET scan for these cancers?
A standard FDG PET scan uses a glucose-based tracer that highlights metabolically active cells. PSMA PET uses a different tracer that binds specifically to the PSMA protein. In prostate cancer, PSMA PET detects disease that FDG PET often misses. In other cancers the comparison is less clear — FDG PET remains the standard for most, and whether PSMA PET adds meaningful information depends on the cancer type and the specific clinical question. Your oncologist's choice between the two depends on which scan is most likely to answer what they need to know.
Is PSMA PET more expensive than a regular PET scan?
Yes. PSMA PET uses a more specialised tracer and is generally more expensive than a standard FDG PET-CT. Through CION's partner imaging centres, PSMA PET is available at an indicative cost of ₹23,999. A standard FDG PET-CT is a separate service with its own pricing. Both figures are indicative — confirm the current cost directly with the imaging centre at the time of booking, as costs are subject to change.
