Breast radiotherapy – side effects

All patients experience a different range and severity of side effects during and after treatment. Most patients suffer relatively minor side effects from breast radiotherapy.

Short term (‘early’) side effects

These are common, occur during or shortly after treatment, and are temporary (as the normal tissues heal after radiation exposure).

Long term (‘late’) side effects

Long term side effects are less common but can appear months or years after treatment. The benefits of radiotherapy almost always outweigh the small likelihood of long term side effects.
