You'll need regular checkups after treatment for a brain tumor. For example, for certain types of brain tumors, checkups may be every 3 months. Checkups help ensure that any changes in your health are noted and treated if needed. If you have any health problems between checkups, you should contact your doctor.
Your doctor will check for return of the tumor. Also, checkups help detect health problems that can result from cancer treatment.
Checkups may include careful physical and neurologic exams, as well as MRI or CT scans. If you have a shunt, your doctor checks to see that it's working well.
The NCI has publications to help answer questions about follow-up care and other concerns. You may find it helpful to read the NCI booklet Facing Forward: Life After Cancer Treatment. You may also want to read the NCI fact sheet Follow-up Care After Cancer Treatment.
