ON THIS PAGE: You will find information about how many children are diagnosed with this type of tumor 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.
PPB is rare. PPB occurs most often in children younger than 12, with most kids diagnosed between the ages of 3 to 4. PPB is rarely diagnosed in teenagers and adults. PPB occurs about equally in boys and girls.
The overall survival rate is the percentage of people who survive after the tumor is found. The overall survival rate of people with PPB is hard to estimate, given the rare nature of this disease. Talk with your doctor about your child’s prognosis and what individual factors it is based on.
Survival statistics should be interpreted with caution. It is not possible to tell a child how long he or she will live with PPB. Survival statistics may not represent advances made in the treatment or diagnosis of PPB. Learn more about understanding statistics .
