A history of exposure to radiation or a family history of thyroid cancer are known risk factors. Tumors of the thyroid are much more common in women. Most tumors are benign. Even if a malignant tumor of the thyroid is found, survival is excellent in most cases. Diagnosis of the tumor usually involves a small needle inserted into the mass in the doctors office.
Treatment generally involves surgical removal of part or all of the thyroid gland.
The salivary glands produce saliva to aid in chewing and digestion. The largest salivary gland is the parotid. People have two parotid glands which are found in front of and below the ears. Malignant tumors will eventually prove lethal if not treated. Surgical removal of the parotid gland is generally curative.
