A 50 year old female patient complains of difficulty in swallowing. Patient gives h/o multiple diagnostic CT-scans of the head and neck region. The incidence of which of the following salivary gland tumor will be more likely in this patient?
Correct Answer: Mucoepidermoid carcinoma
Description: The incidence of salivary gland tumors, both benign and malignant, is increased in patients treated with irradiation for diseases of the head and neck and in Japanese atomic bomb survivors.
Most of the tumors were benign, with Warthin tumor being the most frequent.
Among the malignant tumors, the frequency of mucoepidermoid tumor was highest.
An association between tumors of the salivary glands and dental radiography has been shown, although this association is likely a consequence of more dental radiographs made to investigate the symptoms of an existing tumor, rather than the dental radiation doses inducing tumors.
