Parathyroid Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 06/2017

ON THIS PAGE: You will find information about the number of people who are diagnosed with parathyroid cancer each year. You will read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

Parathyroid cancer is quite rare. Almost all tumors that develop in the parathyroid gland are benign, with parathyroid cancer accounting for fewer than 100 cases per year in the United States. If benign parathyroid tumors are not removed completely or properly, they can come back and be very difficult to control. They may result in hypercalcemia that is difficult to control or could cause death.

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 5-year survival rate for people with parathyroid cancer is about 88%, and the 10-year survival rate is 49%.

It is important to remember that statistics on the survival rates for people with parathyroid cancer are an estimate. The estimate comes from annual data based on the number of people with this cancer 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. People should talk with their doctor if they have questions about this information.
