I hope you're well and that your 3 month follow-up was successful in determining what kind of tumor you have.
Reading your post I was reminded of my own story. They found a tumor April 2007, a CT & MRi, then a biopsy- results indicated a benign tumor.
My symptons continued and I was still looking for answers. Went to another doctor November 2007 and had another CT. The tumor had doubled. Had a liver resection January 2008 and it is cancer, stage II. My 3 month check is coming up and I hope to be clean of cancer.
Keep following up and let me know how you're doing.
