Laurie,
I'm sorry you received this news and are so worried as we all would be. I just wanted to add that my twenty three year survivor friend had a liver mass found last year, it turned out be a benign fibroid after a liver bx.
The onc told her many people have these but most are never found, with our cancer history we get so many scans we're made aware of them.
Just wanted to throw some hope in that it may not be cancer and praying you have the same outcome
