ON THIS PAGE: You will find information about the number of people who are diagnosed with a lacrimal gland tumor each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.
In general, a lacrimal gland tumor is rare. Only 1 out of 1 million people are diagnosed with this type of tumor each year. 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 common epithelial orbital cancer, accounting for approximately 50% of malignant lacrimal gland tumors and 25% of all lacrimal gland tumors. A lacrimal gland tumor can occur at any age.
Survival rates depend on several factors, including the type and subtype of lacrimal gland tumor. The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100.
The 15-year survival rate is estimated to be 25%. However, this and other survival rates depend on several factors, including the type of lacrimal gland tumor and stage of disease. Talk with your doctor about what to expect with your specific diagnosis.
It is important to remember that statistics on the survival rates for people with a lacrimal gland tumor are an estimate. The estimate comes from annual data based on people with this tumor in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information.
