Do you ever fully recover from radiotherapy?

I'm curious, have you or anyone you know ever fully recovered from radiotherapy? It's a serious medical procedure that can have lasting effects on a person's health. Some people report feeling fatigue, skin irritation, and even changes in their appetite and taste. So, I'm wondering, is it possible to fully bounce back after undergoing radiotherapy, or does it leave some sort of lasting impact on a person's body and overall well-being?
