Liver cancer may be difficult to diagnose early because patients often have no symptoms and the cancer often grows quickly. In addition, the liver is located in a place (under the rib cage) that is difficult for a doctor to feel.

In later stages, liver cancer may cause:

discomfort on the right side of the upper abdomen
pain around the right shoulder blade
weight loss
lack of appetite
yellowing of the skin (jaundice)
Other symptoms may include a hard lump just below the rib cage on the right side of the body, fatigue, fever, or weakness.
