- Side Effects of Radiation Therapy
The side effects of radiation therapy depend on the area treated and the
radiation dose. These effects can occur during treatment and are usually
manageable. While most side effects resolve after therapy, some may appear
weeks, months, or even years later. In rare cases, radiation therapy may cause
a secondary cancer decade after treatment, known as a second primary cancer.
