<unk>  is a malignant tumor diagnosed with a biopsy, when a portion of the tumor is removed for examination. In order to ensure that enough tissue is removed to make an accurate diagnosis, the initial biopsy of a suspected<unk>  is usually done with a core needle or a surgical incision. Clinical palpation is not entirely reliable for ascertaining the depth of a<unk>  infiltration. Magnetic resonance imaging (MRI) is more sensitive addressing the depth of the invasion on some types of<unk> , particularly large or recurring tumors. Though MRI is less accurate for identifying infiltration to head and neck tumors.
