Follow-up tests may be needed.

As your child goes through treatment, they will have follow-up tests or check-ups. Some tests that were done to diagnose or stage the cancer may be repeated to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back).

For patients with pheochromocytoma or paraganglioma that causes symptoms, catecholamine levels in the blood and urine will be checked on a regular basis. Catecholamine levels that are higher than normal can be a sign that the cancer has come back. Talk to your child’s doctor about which tests should be done and how often.

Patients with pheochromocytoma or paraganglioma need lifelong follow-up.
