Salivary gland tumors are rare. Swelling of the salivary glands is most commonly due to:
* Abdominal surgery
* Cirrhosis of the liver
* Infections
* Other cancers
* Salivary duct stones
* Salivary gland infections
* Sarcoidosis
* Sjögren syndrome
The most common type of salivary duct tumor is a slow-growing tumor of the
parotid gland. This is usually a noncancerous growth that gradually increases the size of the gland. However, some of these tumors can be cancerous (malignant).
Malignant salivary gland tumors are usually carcinomas.
An examination by a health care provider or dentist shows a larger-than-normal salivary gland, usually one of the parotid glands.
Tests may include:
* X-rays of the salivary gland (called a ptyalogram or sialogram) to look for a tumor
* CT scan or MRI to verify that there is a mass and to see if cancer has spread to lymph nodes in the neck
* Salivary gland biopsy or fine needle aspiration to determine if the tumor is noncancerous (benign) or cancerous (malignant).
I'd suggest that given the nature and serious possibilities of the problem, that you follow up and get another diagnosis from an ENT specialist. I think it's best that you start looking for the cause of the swelling and get some answers ASAP!
