A PET CT scan shows where oral cancer is active in your body, in a single whole-body study. At CION, scans are done at our Hyderabad centres with same-day, expert-reviewed reports and clear, upfront costs — so your tumour board can plan the right treatment without delay.
A PET CT scan combines two tests in one sitting. The PET part uses a small amount of radioactive glucose tracer (FDG) to highlight where cells are most active — cancer cells take up more glucose than normal tissue. The CT part maps exactly where those active areas sit in the body.
For oral cancer, this matters because it answers the questions a local scan cannot:
A PET CT is not needed for every patient. At CION, your tumour board recommends one only when the result will genuinely change your treatment plan — never as a routine, unnecessary test.
Accurate staging changes treatment in a meaningful share of head-and-neck cancers — a whole-body PET CT can reveal spread that a local scan misses, helping the tumour board avoid both under-treatment and over-treatment. (Source: NCCN Head and Neck Cancers guidelines.)
When oral cancer is confirmed and may be advanced, a PET CT maps how far it has spread, so the team can choose the right combination of surgery, radiation, and chemotherapy.
Oral cancer often spreads first to the lymph nodes in the neck. A PET CT helps show which nodes are involved, guiding the extent of surgery or radiation.
If cancer is found in a neck node but the original site is unclear, a whole-body PET CT can help locate the primary tumour that needs treatment.
After treatment, a PET CT can tell active cancer apart from scar tissue, helping detect a return of disease early when more options are open.

Book your PET CT scan with same-day reports and a tumour-board-led review of what the results mean for you.
You will usually fast for four to six hours and avoid heavy exercise beforehand. Tell the team if you are diabetic, pregnant, or breastfeeding. You receive clear, written instructions when your slot is booked.
A small amount of glucose tracer (FDG) is injected through a thin needle. You then rest quietly for about an hour while it spreads through the body. The only discomfort is the brief needle prick.
You lie still on a comfortable bed for about 20 to 30 minutes as the scanner moves around you. The scan itself does not hurt. Plan for two to three hours at the centre in total.
Your report is typically ready the same day and is expert-reviewed. Your oncology team then explains what it means for your stage and treatment in an unhurried, 45-minute consultation. You never read a scan alone.

Start Your Story. Book Free Consultation.A PET CT scan combines two scans in one. The PET part uses a small amount of radioactive glucose (called FDG) to show which areas of the body are most active — cancer cells take up more glucose than normal tissue. The CT part gives a detailed picture of where those active areas sit. Together they help doctors stage oral cancer, find whether it has spread to lymph nodes or other organs, and plan the right treatment.
A PET CT is most useful for staging an advanced or confirmed oral cancer, checking whether it has spread to the neck nodes or beyond, looking for an unknown primary tumour, and detecting recurrence after treatment. It is not needed for every patient. At CION, the tumour board decides whether a PET CT will change your treatment plan, so you only have the test if it genuinely helps.
At CION, a whole-body PET CT scan starts at ₹9,999 for the analog scan and ₹14,950 for the higher-resolution digital scan. The exact cost depends on the type of study your doctor advises. Costs are shared with you upfront, with up to 50% discounts on diagnostics, so there are no surprises on the bill.
You will usually be asked to fast for four to six hours before the scan and to avoid strenuous exercise the day before, because both affect glucose readings. Tell the team if you are diabetic, pregnant, or breastfeeding. Wear loose, metal-free clothing. The team gives you clear, written instructions when your appointment is booked.
The scan itself takes about 20 to 30 minutes, but plan for two to three hours in total. After the tracer is injected, you rest quietly for about an hour so it can spread through the body. The scan causes no real discomfort beyond the small needle prick for the injection. You lie still on a comfortable bed as the scanner moves around you.
At CION, PET CT reports are typically available the same day and are reviewed by an expert before they reach you. Your oncology team then explains what the results mean for your stage and treatment plan in a detailed, unhurried consultation. You never have to interpret a scan report on your own.
The radioactive tracer used is short-lived and the dose is small. For people with cancer, the benefit of accurate staging far outweighs the small radiation risk. The tracer leaves your body within a few hours, helped by drinking water. The team will advise you to keep a short distance from pregnant women and young children for the rest of the day as a simple precaution.
Yes — this is one of its main strengths. Because the scan images the whole body in one sitting, it can show whether oral cancer has spread to the neck lymph nodes, the lungs, bones, or other sites. This helps the tumour board choose between surgery, radiation, chemotherapy, or a combination, and avoids missing disease that a local scan might overlook.
