Being Referred for a PET-CT — Does Not Mean You Have Cancer

No. Being sent to this centre for a PET-CT does not mean you have cancer, and it does not mean cancer is suspected. PET-CT is a specialised imaging technology, and the centres that have it serve patients with many different conditions.

PET-CT uses a small amount of radioactive tracer to show how active different tissues in your body are — not just what they look like. That level of detail is useful in heart disease, inflammation, and neurological conditions, as well as in cancer. The technology is the same regardless of why you need it.

Your referring specialist — the doctor who sent you here — retains clinical responsibility for your diagnosis and your care. They made the decision to request this scan, and they will interpret the results in the context of your full clinical picture.

The imaging team produces a written report describing what the scan shows. That report goes directly to the doctor who referred you. They interpret the findings alongside your symptoms, your history, and your other test results — not in isolation.

The scan does not give you a diagnosis on its own, and no imaging test provides a diagnostic guarantee. Your referring specialist decides what the findings mean for your care and will discuss them with you at your follow-up.

This scan was requested for a specific clinical question that is not a cancer investigation. If the radiologist notices something unexpected, it will be noted in the report. Your referring doctor will decide whether it needs further attention.

PET-CT scanners are expensive and technically complex. They are not available in most hospitals. In practice, the centre that has the equipment serves patients with cancer and patients with other conditions that need the same technology.

You may find it strange or unsettling to be in this environment. The staff here regularly see patients referred for non-cancer reasons. If anything about your visit would be easier with a small adjustment, you can let the reception team know.

Your care is coordinated by the doctor who referred you. Questions about why the scan was requested, or what happens once the results are ready, are best directed to their clinic.
