Living with Mucoepidermoid carcinoma

A type of salivary gland cancer that can first show up as a lump in the face, neck, or mouth.

Understanding Mucoepidermoid carcinoma

Mucoepidermoid carcinoma is a type of cancer of the salivary glands.

Salivary gland cancer is diagnosed in 2 to 3 people per 100,000 each year, and 30 to 35 percent of these are mucoepidermoid carcinomas. It starts when a cell randomly gets changes in genes that control how it divides, so it grows quickly and forms a lump. Early signs may include a lump in the face, neck, or mouth, numbness, weakness, or pain in part of the face, or trouble swallowing.
