Acinic cell carcinoma is a rare type of cancer that develops in salivary glands. This type of cancer is often slow-growing and may not cause symptoms until it has reached an advanced stage. Other synonyms for acinic cell carcinoma include acinar cell carcinoma, acinocellular carcinoma, and acinoid carcinoma. Although these terms may be used interchangeably, they all refer to a cancer that arises in the acinar cells of the salivary glands. Treatment for acinic cell carcinoma typically involves surgery to remove the affected gland, followed by radiation therapy or chemotherapy. Prognosis for this type of cancer is generally good, with a high likelihood of cure if caught early.
