Liver tumours, like tumours of any organ can be classified as primary or secondary.
Metastases
Liver metastases are by far the most common hepatic malignancy, with many of the most common primaries readily seeding to the liver. This is especially the case with gastrointestinal tract tumours, due to portal drainage through the liver 2.
