Liver tumor

I am healthy and recently had a Calcium scan done to check for heart disease based on a strong family history of CAD. My doctor is concerned about a spot on my liver that showed up on the scan and has scheduled a CT scan of the abdomen. He told me not to lose sleep over this but I can't help but be concerned. I've looked online at the three common benign liver tumors, but it seems that a liver biopsy is the only way to be sure that a liver tumor is not malignant. Please elaborate.
Thanks.

I hava the same thing.  I recently had an ultrasound and doctor saw two spots and ordered ct scan.  I am really worried.

Did you had your ct scan done?  What did they found ?

Thanks.
