Facing radiation therapy can feel overwhelming, especially if it’s your first time. But knowing what to expect and how to prepare can make a world of difference.

Step 1: Medical Preparation – Team Up with Your Healthcare Providers
The first and most important step is working closely with your care team. They’re here to help you navigate every part of the process.
-
Consult Your Care Team
Your oncologist and radiation therapist will walk you through your specific treatment plan, so don’t hesitate to ask questions. -
Pre-Treatment Scans
You may need imaging such as CT, MRI, or PET scans to pinpoint exactly where the radiation should be focused. -
Skin Care Instructions
Avoid using lotions, perfumes, or powders on the treatment area unless your doctor says it’s okay. -
Dental Checkup
If your treatment involves the head or neck, seeing a dentist beforehand helps prevent complications like infections. -
Review Medications
Make sure your doctor knows about all medications, vitamins, and supplements you’re taking. Some may need to be adjusted. - WATCH to UNDERSTAND MORE about Radiation
Step 2: Lifestyle Adjustments – Support Your Body Through Treatment
Making a few healthy lifestyle changes can help your body cope better with radiation and its side effects.

Choose nutrient-rich foods to maintain strength and energy. A registered dietitian can help you create a personalized meal plan. -
Stay Hydrated
Drink plenty of fluids to help your body recover and stay energized. -
Get Plenty of Rest

Step 3: Emotional & Mental Preparation – Calm Your Mind
Radiation therapy isn’t just a physical journey—it’s an emotional one too.
-
Ask Questions
The more you know about your treatment, the less intimidating it will feel. -
Build a Support System

-
Arrange Transportation
You may feel fatigued, especially after treatment. Have a friend or family member drive you when needed. -
Plan for Time Off
Depending on your side effects, you might need to reduce your work hours or take time off entirely. -
