Hi, trishaphifer,
Welsome to the boards.
You should probably read and join in on discussions on the
Focal Nodular Hyperplasia and
liver adenoma or focal nodule hyperplasia threads.
All of our us had our growths discovered in the same way you've described - found in scans done for other reasons.
Hopefully, if it's a GP you've seen so far, they will send you to a liver specialist next.
I had an FNH which did cause me pain, although my growth was on the left lobe. Apparently, they can cause pain for some of us.
If if does turn out it is a liver adenoma or focal nodule hyperplasia, you'll find lots of answers, info and support here.
Good luck.
