Side Effects

This list doesn't represent all of the possible side side effects. The side effects you might experience will depend on the part of the body being treated, the dose of radiation given and whether you also receive chemotherapy. Before treatment begins, ask your doctor about possible side effects and how best to manage them. 

This is a visual side effects chart showing short and long term side effects. Larger bubbles show higher likelihood of occurrence. To see a larger version, click on the chart.
