[|Human|] My Husband had a spiral CT scan done to detect cancer. A spot showed up in his lung and liver, he then had a PET scan done which only showed the lung spot. He had successful lung cancer surgery. Now the spot on the live has doubled. Because it was present but did not show up on the PET scan can we be optimisic that it is not cancer but something else?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Your husband has history of lung cancer, and he was treated successfully. Now spiral CT scan shows spot on liver and lung. But his positron emission tomography does not show any spots on liver. There is chance that it can be due to metastatic lung cancer. You should keep close watch on that. If it is increase in size then USG guided FNAC or biopsy should be done to confirm or rule out the diagnosis. Then he should take treatment accordingly.
