Oral ulcer 10 days bad can cancerous

Oral ulcer is a common oral mucosal disease, usually healing within 12 weeks. But if the oral ulcer continues for 10 days, although it cannot be directly judged as cancer, it does need to be taken seriously. The following are some possible reasons and analysis: 1. Local irritant factors persist If there are residual roots, crowns, bad prostheses and other parts of the mouth that continue to stimulate the ulcer, it may affect its healing and lead to a longer healing time. In this case, after removing the irritant factors, the ulcer may gradually heal rather than cancerous. 2. Individual differences vary in the healing ability of different people, and some people may take longer to recover. However, if there are many oral ulcers that do not heal for a long time, more attention needs to be paid. 3. Systemic factors The health status of the body will also affect the healing of oral ulcers, such as low immunity, malnutrition, endocrine disorders, etc. Improving the general condition may help promote ulcer healing. 4. May be other diseases In addition to the common recurrent oral ulcers, there are some other diseases that may be manifested as oral ulcers that do not heal for a long time, such as Behcet's disease. Further examination and diagnosis are needed to clarify. Malignant diseases such as oral cancer may manifest as symptoms similar to oral ulcers in the early stage. If the ulcer shape is irregular, the base is hard, the pain is not obvious, or accompanied by abnormal manifestations such as swelling and induration of surrounding tissues, it is necessary to seek medical advice in time for further examination such as biopsy to confirm the diagnosis.
