Liver lesions??????????

I had all my pretesting done on February 24th. I finally called my doc back after him leaving me a message on Friday and he tells me I have lesions on my liver. WTF! I now have a cat scan scheduled for the 12th. I see my surgeon on the 10th. I am really going to scream if this holds up my surgery. Has anyone else out there ever had lesions on their liver. Webmd does not tell you anything.
