Tongue cancer has a high incidence in the anatomical regions and tissues of the oral cavity and is predominantly squamous cell carcinoma. In the early stage of tongue cancer, this cancerous lesion can be seen as ulcerative proliferation, which manifests as long lasting heavy ulcers with depth up to the muscle layer, and the soft tissues around the margins of tongue cancer are hard and have no clear boundaries. When touching the ulcer and surrounding tissues, it can cause pain. Mechanical irritants can be seen at the edge of tongue cancer, such as sharp-edged stump crowns, stump roots, and poorly restored denture with rough and uneven surface. On the surface of tongue cancer, sometimes the ulcers can be seen as granular cauliflower-like growth, which can cause swelling of chin and submandibular lymph nodes on the same side. If the disease develops further, the enlarged lymph nodes can be fused into a mass.
