Parotid tumors are divided into benign parotid tumors and malignant parotid tumors. Benign parotid tumors are similar to benign tumors in other parts of the body, which are not particularly harmful to the human body, except that excessive growth of the tumor will affect the face shape, and the swelling growth can produce certain pressure on the surrounding tissues, which may cause some discomfort, but benign tumors of parotid glands are usually not harmful to the human body’s life. Malignant tumors of the parotid gland are more harmful, destroying the facial nerve in the early stage, causing local symptoms of facial paralysis, such as incomplete closing of the eyes, crooked corners of the mouth, and leakage of air. There will also be local lymph node metastasis, distant metastasis, such as lung metastasis, which will cause fatal injury to human body.
