Question
What are the symptoms of malignant parotid tumors?
Answer
The symptoms of malignant parotid tumors include slow growth, hardness in texture, smooth or nodular surface, possible pain during movement, and facial paralysis. If the tumor invades tissues outside the gland, it may become fixed and painful. Malignant mixed tumors and mixed tumors that undergo malignant transformation typically grow slowly but may suddenly shrink significantly within a few months, accompanied by regional pain, numbness, or facial paralysis, which may indicate malignant transformation. Malignant mixed tumors have a poor prognosis, are prone to metastasis to the lungs, bones, and brain, and usually result in death within one year after metastasis. It is advisable to seek treatment as early as possible.
