This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a simple method—where your surgeon carefully measures the tissue removed during oral cancer surgery using a ruler—works just as well as a more expensive laboratory test called frozen section analysis. Both methods aim to ensure your surgeon removes enough healthy tissue around the cancer to reduce the chance it comes back.
Frozen section analysis is widely used to check surgical margins during oral cancer surgery, but recent research suggests it may not actually improve patient outcomes. Additionally, this test is expensive and not available in many parts of the world. This trial will determine whether the surgeon's direct measurement is just as effective and could save time and cost.

You will have oral cancer surgery as planned. During the operation, you will be randomly assigned to one of two groups: one group will have their surgical margins checked by the surgeon using a ruler and direct measurement, while the other group will have their margins tested using the frozen section laboratory method. Both approaches happen during your surgery, so you won't need extra visits or procedures beyond your planned operation.
