To Assess the Correlation of High-resolution Specimen PET-CT Imaging, Using the XEOS AURA 10 PET-CT, With the Histopathology Results and Long-term Outcome of Patients Undergoing Resective Cancer Surgery.

This study is testing a specialized high-resolution PET/CT scanner (the AURA 10) that images removed cancer tissue immediately after surgery, to see how well these detailed images match what the pathologist later finds under the microscope — with the goal of improving real-time surgical decision-making. **You may be eligible if...** - You are 18 or older - You are scheduled for or have already had cancer surgery where the removed tissue was imaged with the AURA 10 PET-CT - The imaging was successfully completed (captured at least part of the tumor with no major technical problems) - You are willing to allow your relevant medical records to be used **You may NOT be eligible if...** - You are under 18 years old - You are pregnant or breastfeeding - Successful imaging was not achieved during your surgery Talk to your doctor to see if this trial is right for you.
