Radiation Therapy Side Effects: What to Expect and How to Manage Them

Every patient is unique, but there are common side effects during radiation therapy. Knowing about them in advance helps you prepare, prevent, and manage them better.

What Are Acute Side Effects?

Acute side effects occur during treatment or in the weeks afterward. They vary depending on the treated area:
• Red or irritated skin (similar to a sunburn).
• General fatigue.
• Discomfort when swallowing (with neck or chest radiation).
• Nausea or diarrhea (with abdominal or pelvic radiation).
• Urinary or rectal changes (with prostate or cervical radiation).

These symptoms don’t always happen and are usually temporary. They can be managed with medications and daily care.

What About Late Effects?

These may appear months or years later and are less common. Some examples include:
• Changes in skin texture (thickening or fibrosis).
• Stiffness or limited mobility.
• Persistent urinary or sexual changes.
• Slight risk of other cancers in the future (less than 1%).

Your medical team monitors these risks and will schedule regular follow-ups.

How Can I Take Care of Myself?

• Wear loose, non-irritating clothing.
• Keep your skin moisturized with recommended creams.
• Get plenty of rest.
• Follow a healthy diet.
• Inform your doctor if anything changes.

Most patients complete radiation therapy without serious complications. The key is staying alert and maintaining open communication. Your well-being is our priority.
