ON THIS PAGE: You will find information about the number of people who are diagnosed with a pheochromocytoma or paraganglioma each year. You will also read general information on surviving these diseases. Remember, survival rates depend on several factors. Use the menu to see other pages.
Pheochromocytomas and paragangliomas are rare. In the United States, about 2 to 8 people per every 1 million people are diagnosed with these tumors each year. Around 100 to 200 of these cases are malignant. Paragangliomas are far less common than pheochromocytomas.
Pheochromocytomas affect men and women equally. The tumor can be diagnosed at any age, but it is most common between the ages of 30 and 50. Approximately 10% of these tumors are diagnosed in children. The average age of diagnosis for a pheochromocytoma linked to a hereditary cause is 24 (see Risk Factors).
The 5-year survival rate tells you what percent of people live at least 5 years after a tumor is found. Percent means how many out of 100. However, the survival rate depends on many factors, including the location of the tumor and its stage.
Localized pheochromocytomas have a 5-year survival rate of 95%. The 5-year survival rate for a pheochromocytoma that has spread or recurred is estimated to be between 50% to 60%.
It is important to remember that statistics on the survival rates for people with a pheochromocytoma or paraganglioma are an estimate. The estimate comes from annual data based on the number of people with these tumors 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 any questions about this information.
