what you need to know about radiotherapy side effects

What does radiation do to your body

During  radiotherapy your cells are damaged by destroying the genetic material that controls how cells grow and divide. The damage can occur to healthy as well as cancerous cells, but your healthy cells are able to repair themselves during this time, which can result in a variety of side effects. This can occur during or after treatment or it can take a number of months or years to occur.

There are some early side effects that usually occur during or after treatment and are usually short-term, mild, and treatable. They typically disappear within a few weeks after treatment ends. 
Late Side Effects 

Late side effects can take months or even years to develop and affect the tissue in the body where the treatment was given. The risk of late side effects depends on the area treated as well as the radiation dose that was used.
