On chemo for metastic colon cancer . ct scan coming up - says neck, thorax , abdomen and pelvis . is neck usually scanned ?

Not usually, but...: Generally colon cancer spreads to the lymph nodes, liver and lungs, so those are the first organs looked at to see if it has spread or not. However, another symptom or physical finding may prompt a doctor to include another area of the body, such as the neck or brain.

Yes: There are multiple sites where metastatic colon cancer can appear. While the liver and lung are the most common visceral sites other than lymph nodes in abdomen , spread can occur to the left supraclavicular fossa. Troisier sign is the finding of a hard and enlarged left supraclavicular neck node (Virchow's node). It is a sign of metastatic abdominal malignancy draining the thoracic duct.
