Thank you so much for the information Colleen! I'm waiting for my surgeon and my oncologist to talk (and it's taking forever!) So right now I don't have a follow up appointment. The lesion/tumor/whatever was found when I had an ultrasound done because of gallbladder issues. I'm having the gallbladder removed and a biopsy of the spleen will be taken at that time. Waiting is the hardest part.
