Can radiation be given twice to the same area?
Whether radiation will be used after recurrence depends on many factors.

It depends on the amount of radiation that was used before.
Do tumors grow back after radiation?

How do you know if radiotherapy has worked?
There are a number of ways your care team can determine if radiation is working for you.
