question: My mom had small bowel cancer in August. They did a complete tumor resection and now she has pain in her lower left abdomin. They did bone scan and ct scans multiple and didnt see anything. Yesterday she went to see the surgeon and he didnt like the way her belly button area is swollen and sore. He thinks there may be a lump there and wants to remove it. Would abdominal ct scans show a cancerous tumor by her belly button or is it more likely a surgerical hernia? Is the belly button surgery difficult to recover from? Shes 83 years old.
