What Is Parotid Cancer?
Parotid cancer is a malignant tumor that occurs in the parotid gland and belongs to a type of malignant tumor with the highest incidence among salivary gland cancers. It is more clinical than unintentional or found during experience. There is a slow growing painless mass below or behind the earlobe. It is mostly nodular, with a flat or slightly rounded surface. The texture is different in hardness and activity. The size is generally 3 -5 cm, with capsule, long history, except for local soreness, no facial nerve damage, regional lymphadenopathy and other discomforts. Parotid malignant tumors are rare, with malignant mixed tumors being the most common, followed by mucoepidermoid tumors, adenocarcinomas, acinar cell carcinomas, and papillary cystadenocarcinomas. The clinical manifestations are short course of disease, rapid growth, pain in the lesions, numbness and discomfort, hard masses, adhesion to deep tissues, poor mobility, difficulty in opening mouths, partial patients with partial or full facial nerve paralysis, infiltration of the skin can rupture, wounds Unhealing, malodorous secretions, metastasis to cervical lymph nodes or distant metastases (lung, bone, liver, brain, etc.) can occur.

Parotid cancer
- Parotid cancer is a malignant tumor that occurs in the parotid gland and belongs to a type of malignant tumor with the highest incidence among salivary gland cancers. It is more clinical than unintentional or found during experience. There is a slow growing painless mass below or behind the earlobe. It is mostly nodular, with a flat or slightly rounded surface.

Parotid cancer pathology
- The cause of this disease in modern medicine is not yet clear. Some scholars believe that it is related to the virus or infection. The clinical diagnosis is mainly based on medical history, symptoms, systemic and local examinations; X-ray imaging of salivary glands shows that the main and branch ducts are squeezed and twisted, dilated, narrowed and discontinued, and interrupted. Poor or defective acinar fillings or sheet-like contrast spillage; When the main duct was infarcted, all the branch ducts and glands were not visualized. Needle aspiration of living tissue or frozen tissue biopsy during pathological examination can confirm the diagnosis.
Treatment of parotid cancer
- Modern medicine mainly uses surgical resection for the treatment of this disease. The 5-year survival rate for parotid cancer is reported to be around 95%. When the patient's malignant tumor has invaded the surrounding tissue and residual cancer remains at the margin after surgery, supplementary radiation therapy should be considered.
- The disease belongs to the categories of "bumps", "sputum" and "lithothrax" in Chinese medicine. Traditional Chinese medicine believes that the disease is caused by the contents of fever, stasis of qi and blood, and accumulation of phlegm and dampness.
