How to Care for Your Skin During Radiation for Colon and Rectal Cancer
A Compassionate Patient Guide
Introduction: Caring for Sensitive Skin During Treatment
Radiation therapy for colon and rectal cancer plays a vital role in destroying cancer cells and reducing recurrence risk. Yet, it can also irritate the delicate skin around the lower abdomen, buttocks, and anal region.
Because these areas are both sensitive and hard to reach, daily care can be challenging—and sometimes embarrassing to discuss. But you’re not alone.
This guide shares oncology-nurse-formulated strategies to help you stay comfortable and maintain healthy skin throughout treatment. It explains how to use Dermavitality Radiation Relief Spray and Cream, featuring Arnica, Calendula, Aloe Vera, and Chamomile, to calm, cool, and hydrate even the most delicate areas with confidence.
1. Why Skin Reactions Occur in Colon & Rectal Radiation Therapy
Radiation beams must pass through surface layers of the lower abdomen and buttocks to reach the rectum or colon. As Memorial Sloan Kettering Cancer Center notes, treated skin may become red, dry, warm, or sore during therapy (mskcc.org).
For colon and rectal cancer patients, this happens because:
- The perianal area stays warm and moist, creating friction.
- Sitting pressure and bowel movements re-irritate sensitive skin.
- Cleansing or wiping can sting or remove protective oils.
- Moisture and bacteria can cause infection if the skin breaks down.
Gentle daily care and moisture balance are the best defenses.
2. What to Expect During Treatment
Skin reactions often appear by week 2 and peak near the end of therapy.
Typical changes include:
- Redness or darkening around the anus or buttocks
- Burning, itching, or stinging with bowel movements
- Dryness or cracking near the tailbone
- Weeping or open skin in folds
Macmillan Cancer Support emphasizes daily gentle cleansing and moisturizing to limit these effects (macmillan.org.uk).
3. The Challenge of Hard-to-Reach Areas
Applying creams to the rectal region can be painful, messy, and unhygienic. The Dermavitality Radiation Relief Spray solves this problem with a touch-free fine mist that reaches folds and perianal skin safely—no rubbing required.
It provides cooling comfort and helps maintain hygiene between cleansings, a major benefit during daily radiation sessions.
4. Step-by-Step Daily Skin-Care Routine

6. Importance of Frequent Moisturizing

- Apply the Spray 3–4× daily to keep moisture and comfort steady.

BC Cancer recommends moisturizing from the start of therapy and increasing frequency as reactions develop.
7. Hygiene, Clothing & Comfort Tips

- Avoid perfumed soaps or alcohol-based wipes.
- Pat dry or air-dry — never rub.
- Skip powders and talc.
