## Lacrimal Gland Tumor - Statistics [1]

**ON THIS PAGE**: You will find information about how many are diagnosed with this type of cancer each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

In general, a lacrimal gland tumor is rare. About half of lacrimal gland tumors are benign, and half are malignant. Malignant epithelial tumors of the lacrimal gland account for 2% of all orbital (eye socket) tumors. Adenoid cystic carcinoma (AdCC) is the most frequent epithelial orbital cancer, accounting for approximately 50% of malignant lacrimal gland tumors and 25% of all lacrimal gland tumors.

Survival rates depend on several factors, including the type and subtype of lacrimal gland tumor. The five-year survival rate is the percentage of people who survive at least five years after the cancer is found. The five-year survival rate of people with AdCC is estimated to be 50%, while the 15-year survival rate is estimated to be 25%.

Survival statistics should be interpreted with caution. Estimates are based on data from many cases of this type of tumor in the United States each year, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with a lacrimal gland tumor. Because the survival statistics are measured in multi-year intervals, they may not represent advances made in the treatment or diagnosis of a lacrimal gland tumor.
