If your doctor tells you that have a hepatic adenoma, it means you have a liver tumor that is "benign." That's another way of saying that it isn't cancer. It won't spread to other parts of your body.
Carcinoma ex-pleomorphic adenoma (CXPA) is a type of cancer that develops in the salivary glands. This type of cancer develops from an existing tumor that was previously benign (noncancerous).
