My father has parotid gland cancer. Help me.

Parotid carcinoma is a malignant tumor that occurs in parotid gland and belongs to the malignant tumor with the highest incidence among salivary gland adenocarcinoma. Clinically, there are painless masses with slow growth below or behind the earlobe, mostly nodular, with flat or slightly round surface, different hardness, large mobility, general size of 3-5 cm, capsule, long medical history, no facial nerve injury, regional lymph node swelling, and no other discomfort except local pain. Malignant tumors of parotid gland are rare, mostly malignant mixed tumors, followed by mucoepidermoid tumors, adenocarcinoma, acinar cell carcinoma and papillary cystadenocarcinoma. The clinical manifestations are short course of disease, rapid growth, pain, numbness, discomfort, lumps, adhesion to deep tissues, poor activity and difficulty in opening mouth. Some patients have partial or total paralysis of facial nerve, which may lead to skin ulceration, unhealed wound, smelly secretion, cervical lymph node metastasis or distant metastasis (lung, bone, liver, brain, etc. ) will happen.

The etiology of this disease in modern medicine is still unclear. Some scholars believe that it is related to viruses or infections. Clinical diagnosis is mainly based on medical history, symptoms, general and local examination; X-ray examination of salivary gland showed that the main and branch ducts were twisted, expanded, contracted and interrupted; The alveoli are poorly filled or defective, or the contrast agent overflows in pieces; When the main duct is infarcted, all the branch ducts and glands are undeveloped. Diagnosis can be made by needle aspiration of biopsy or pathological examination of frozen section of biopsy during operation.

The treatment of this disease in modern medicine mainly adopts surgical resection. It is reported that the 5-year survival rate after parotid gland cancer surgery is about 95%. Adjuvant radiotherapy should be considered when the patient's malignant tumor has invaded the surrounding tissues and there is still residual cancer on the postoperative edge.

This disease belongs to the category of "cheek sore", "phlegm flow" and "gangrene" in traditional Chinese medicine. Traditional Chinese medicine believes that the disease is caused by heat toxin, blood stasis and phlegm-dampness accumulation.
