Should i be concerned about two shadows being found on the ct scan of my liver?

It depends: Most findings are benign. However, you need to ask your doctor what these mean - Do they appear benign? Are they worrisome for cancer? What are they (cysts, adenomas, etc)? Are you at risk for liver cancer (do you have cirrhosis) and need to be concerned about this. Please talk with the physician who ordered the study to see what these spots may be.
