Symptoms of oral cancer
Early symptoms: painless or only sensory abnormality or slight tenderness, accompanied by lump ulcer, obvious pain occurs, but the degree of pain is not as severe as inflammation.
Late symptoms: Ulcer occurs, which is characterized by hard quality, irregular edge uplift and uneven infiltration mass at the base. The ulcer surface spreads to the whole tumor area, and suddenly cervical lymph node enlargement appears.
Related symptoms: ulcer, oral pain, white and hard raised plaque on oral mucosa
Early oral squamous cell carcinoma is generally painless or only sensory abnormality or slight tenderness, and obvious pain occurs when it is accompanied by mass ulcer, but the degree of pain is not as severe as inflammation. Therefore, when the patient complains of pain, especially gingival pain or tongue pain, he should carefully check whether there is induration, lump and ulcer in the pain. If there is pain or tongue pain, carefully check whether there are induration, lump and ulcer in the pain area. There are the above signs in bitter and painful areas, and cancer should be highly suspected.
In oral cancer, tongue cancer and gingival cancer complained of pain in early stage. If the pain site does not match the site of oral mass ulcer, it is necessary to consider the possibility of tumor spreading to other sites. Toothache can be caused by gingival cancer, and can also be caused by buccal mucosa cancer, hard palate cancer, mouth floor cancer or tongue cancer spreading and invading gingival or lingual nerve. Ear pain and sore throat can be symptoms of oropharyngeal carcinoma, and can also be caused by tongue body cancer invading tongue base or cheek, hard palate and gum, or lateral mouth floor cancer invading lateral pharyngeal wall backward.
Oral squamous cell carcinoma can present superficial infiltrating plaque when it is located superficially, and it is difficult to distinguish it from leukoplakia or hyperplastic erythema without biopsy.
Ulcer often occurs in oral squamous cell carcinoma, which is typical of infiltrating mass with hard quality, irregular edge and uneven base, and the ulcer surface affects the whole tumor area.
Oral squamous cell carcinoma originates from oral mucosal epithelium, and its mass is formed by proliferation of squamous epithelium. No matter to the oral cavity ulcer or deep infiltration, the mass formed by it is superficial, and cancer tissue lesions can always be seen on its mucosa. In addition, most oral cancers metastasize to the nearby cervical lymph nodes first, sometimes the primary focus is very small, and even the symptoms are not obvious, and the cervical lymph nodes have metastasized and become larger. Therefore, if the neck lymph nodes suddenly appear, you should also carefully check the oral cavity
Second, diagnostic criteria
Once it is clinically determined that the mass comes from oral cancer, the scope and depth of invasion should be further judged. When accompanied by sensory abnormalities such as sore throat, earache, nasal congestion, epistaxis, difficulty in opening mouth, limited tongue movement, pain and numbness in trigeminal innervation area, it should be considered that the tumor may have invaded oropharynx, maxillary sinus, nasal cavity, extralingual muscles, masticatory space and mandible, so as to further infer by selecting appropriate visual examination in combination with the location of oral cancer.
