I have two tumors on my liver, very small ones, about 1 cm each. They are located close to my lung so the intervention radiologist does not want to do a biopsy but instead wants to do another CT scan in 3 months. I have asked about doing a PET scan which shows increased sugar uptake in cancer cells to see if we can determine whether the tumors are cancerous. The gastroenterologist however gives me a blank look and says that only oncologists order PET scans, not him. This seems an inadequate explanation to me. When I asked why, he just stammered and didn't really answer me.
Should I return to my GP for another referral or is this normal? Should I just wait he 3 months for another CT to see if the tumors grew? By way of background, my blood tests were all normal, no hepatitis, no chirrosis, no tumor markers.
I would appreciate any insight or experience people have. I understand that most liver tumors are benign but it is hard not to worry.
