Clinically, oral cancer in patients can be detected through imaging.

Oral cancer is a general term for a major category of malignant tumors in clinical settings, including tongue cancer, lip cancer, buccal mucosa cancer, gingival cancer, and cancer of the oral floor, among others. Imaging can reveal the size of oral cancer tissues, the scope of involvement, the adjacency to surrounding tissues, and the extent of invasion into surrounding tissues, thus clarifying the range of the oral cancer lesions.

However, to diagnose oral cancer clinically, imaging examinations alone are insufficient. A tissue biopsy of the oral cancer lesions is also required to obtain pathological results for a definitive clinical diagnosis. Once diagnosed, imaging is then used to assess the clinical stage of the patient, and individualized anti-tumor treatment measures are taken based on different stages.
