Possible Side Effects

• Side effects are usually temporary and should go away after treatment ends. However, ask your doctor what you can expect from your specific treatment.
• Skin irritation similar to sun burn.
• Mild to moderate breast swelling.
• Mild fatigue that generally gets better a month or two after treatment ends.Some women describe this as an overall "blah" feeling.
• A few women report mild tenderness in the breast or chest wall. This will slowly get better over time.
• Scarring of a small part of the lung just under the breast. This generally does not cause side effects.
• Many of these side effects can be controlled with medications. Tell your doctor or nurse if you experience any discomfort so they can help you feel better.
