Can PET/CT confirm cancer diagnosis?
A PET/CT scan is a powerful tool in the diagnosis and staging of cancer, but it cannot definitively confirm a cancer diagnosis on its own.

However, a conclusive diagnosis often requires additional steps such as biopsy or further imaging studies.

Some patients may experience slight discomfort from the injection site or mild allergic reactions. It is important to inform your doctor of any allergies or existing medical conditions before the scan.
