Can a pet scan show benign tumors?

Yes, a PET scan can show benign tumors, as it detects areas of increased metabolic activity in the body. However, while PET scans can indicate the presence of a tumor, they cannot definitively determine whether a tumor is benign or malignant. Additional imaging studies, biopsies, or clinical evaluations are often necessary to make an accurate diagnosis. Therefore, while benign tumors can be identified on a PET scan, further investigation is typically required for confirmation.
