What is the most common characteristic symptom of malignant tumors occurring in the lower jaw?

The most common characteristic symptom of malignant tumors in the lower jaw is paraesthesia. This symptom refers to abnormal sensations, such as tingling or numbness, in the affected area. In the case of malignant tumors, the growth can irritate or compress nearby nerves in the jaw, leading to paraesthesia, which may manifest as a tingling feeling or a loss of sensation.

This symptom is particularly important because it often indicates nerve involvement, which is a common feature of malignancy. As the tumor progresses and invades surrounding tissues, the disruption to nerve function tends to become more noticeable, making paraesthesia a significant indicator in the clinical evaluation of patients who may have lower jaw tumors. Recognizing this symptom can lead to timely diagnosis and management of potentially serious conditions associated with malignant tumors.
