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 childhood extracranial germ cell tumors, follow-up may include regular physical exams, tumor marker tests, and imaging tests such as CT scan, MRI or chest x-ray.
