Tumors of epithelial origin of the salivary glands are the most common disease of salivary gland tissue, the vast majority of which are epithelial, with tumors of mesenchymal tissue origin being less common and may be benign or malignant.
In macrosalivary gland tumors, the smaller the gland, the greater the likelihood that the tumor will be malignant. Of parotid gland tumors, most are benign about 75% and malignant about 25%; of submandibular gland tumors, benign tumors account for about 60%.
In sublingual gland tumors, the proportion of malignant tumors is as high as 90%, and benign tumors only account for a very small number. Among minor salivary gland tumors, malignant tumors accounted for about 60% and more than benign tumors.
It is suggested that once patients are diagnosed with salivary gland tumors, they should go to regular hospitals as early as possible for diagnosis and treatment, and after judging the nature of the tumor and the degree of development of the disease, they should take corresponding standardized treatment in time, and most of the patients can get long-term survival.
