Understanding Radiation Therapy and the Skin
Radiation therapy (RT) is a cornerstone treatment for various cancers, using targeted high-powered radiation to destroy malignant cells. However, skin cells in the treatment field also absorb radiation, leading to distinctive changes in skin health and appearance. Since skin cells proliferate rapidly, they are susceptible to radiation-induced damage, especially when they lack time to recover between treatments.
Why Does Skin React to Radiation?
During external beam radiation, radiation passes through the skin to reach cancerous tissue. Collateral damage disrupts the renewal of healthy skin cells, resulting in various acute and chronic reactions. Side effects often occur several weeks into therapy but vary depending on dosage, frequency, and patient factors.
Common Skin Reactions During Radiation
The majority of patients (up to 95% in some populations, such as breast cancer) will develop some degree of radiation-induced skin changes, broadly termed radiation dermatitis. These changes include acute (short-term) and chronic (long-term) effects:
- Reddened, sunburn-like skin (erythema)
- Itching, peeling, or dryness
- Bumps, rashes, or soreness
- Swelling or localized edema
- Thinning or thickening of skin
- Darkening (hyperpigmentation) or, rarely, lightening (hypopigmentation)
- Hair loss in the treatment area (temporary or permanent)
- Skin sensitivity or numbness
- Delayed, poorly healing sores or ulcers (in severe cases)
Acute reactions usually resolve after therapy, but chronic changes—such as persistent pigmentation, skin atrophy, or fibrosis—may linger.
Factors Influencing Skin Reactions
- Treatment-related Factors: Total radiation dose, frequency, technique, use of bolus or concurrent chemotherapy can exacerbate reactions.
- Patient-related Factors: Nutritional status, age, skin type, preexisting skin conditions, body habitus (obesity), history of smoking or alcohol use, and comorbidities affect the risk and severity.
- Location of Radiation: Skin folds, moist areas (under breast, groin), and scalp are more prone to severe reactions.
- Personal Hygiene and Skin Care Practices: Use of irritating products, aggressive washing, or friction can worsen symptoms.
Preventive Skin Care Strategies
Proactive, gentle care from the outset of therapy can mitigate discomfort and prevent severe skin reactions.
- Start skin care before treatment begins. Emollient creams and gentle skincare should be used one to two weeks prior to the first radiation session.
- Daily application of a topical steroid (as prescribed) during and after treatment may reduce inflammation and severity.
- Film-forming silicone gels have evidence for reducing acute reactions and can be started with radiotherapy.
- Use of mild, fragrance-free moisturizers can maintain skin barrier function.
Evidence-Based Daily Skin Care Routine
| Step | Instructions |
|---|---|
| Cleansing | Use a gentle, fragrance-free soap and lukewarm water. Avoid vigorous scrubbing; pat the area dry gently. |
| Moisturizing | Apply an unscented, hypoallergenic moisturizer or emollient cream daily—ideally within 10-15 minutes after bathing—avoiding broken skin. |
| Sun Protection | Protect the area from sun exposure using a high-SPF, broad-spectrum physical sunscreen or loose clothing. |
| Clothing | Wear soft, breathable, loose-fitting fabrics (like cotton). Avoid tight, rough, or synthetic clothing over the treated area. |
| Other Products | Discontinue use of deodorants, perfumes, makeup, and powders on the treatment site unless approved by your care team. Evidence increasingly supports that deodorant use is safe for most patients if preferred. |
| Shaving | Avoid shaving the treated skin, or use only electric clippers—not razors. |
Key Daily Habits
- Gently cleanse the area once per day.
- Apply moisturizer at least twice daily, but not immediately before therapy sessions (to avoid residue interfering with treatment).
- Check the skin daily for new changes or symptoms.
Managing Skin Irritation and Radiation Dermatitis
Despite best efforts, nearly all patients will experience some symptoms. Early intervention is vital to reducing discomfort and risk of infection.
Acute Management Steps
- Topical steroids (as prescribed) for inflammation—beginning before and continuing through the full radiation course plus 1-2 weeks post-treatment.
- Film-forming silicone gels or dressings (such as Mepitel Film®, hydrocolloids, or silver dressings) for moist desquamation and open areas.
- Non-adherent dressings for areas with broken or peeling skin.
- Pain management—pain-relieving creams or oral analgesics as directed by a physician.
- Avoid friction and trauma. Do not scratch, rub, or irritate the area further.
Additional Supportive Measures
- Photobiomodulation therapy (LED light) may be used for some resistant wounds.
- Gentle cooling (cool compress) to relieve itching or burning.
- Hydration and a balanced diet to promote healing.
- Psychological support, especially if visible changes affect self-image.
When Wound Care Is Needed
- If skin breaks open (moist desquamation), keep it clean and covered with a sterile, non-stick dressing changed daily or as directed.
- Seek professional advice on wound care dressings and infection prevention.
Products and Ingredients Recommended
Moisturizers and Emollients
- Unscented, hypoallergenic creams or ointments (e.g., Aquaphor, Cetaphil, Eucerin)
- Cocoa butter (especially for darker skin types), but start only after healing if hyperpigmentation occurs
- Avoid products with alcohol, fragrances, or exfoliants
Topical Steroids
- Low to medium potency as prescribed—do not use on open wounds
Silicone Gels and Advanced Dressings
- Film-forming silicone gels (e.g., StrataXRT®, ScarAway®)
- Advanced with dressings (hydrocolloids, Mepilex®, hydrofilm, silver-impregnated dressings for infection)
Sun Protection
- Physical/mineral sunscreen (zinc oxide or titanium dioxide, fragrance-free)
- Protective clothing and wide-brimmed hats for outdoor exposure
Long-Term Skin Care After Radiation
Some skin changes may persist or surface months after therapy. These chronic effects require ongoing care and monitoring:
- Persistently dry or tight skin—continue regular moisturizing for life.
- Hyperpigmentation—skin lightening agents (hydroquinone, tretinoin) may be considered, but only after full healing and at least two months post-radiation.
- Atrophy, fibrosis, or scarring—physical therapy and, in some cases, vitamin E plus pentoxifylline (requires prescription).
- Sun sensitivity—increased life-long risk for skin cancer mandates use of sunscreen and regular skin checks.
When to Contact Your Healthcare Provider
Prompt communication with your oncology team ensures safe management of any complications. Seek immediate advice if you notice:
- Severe redness, pain, or swelling
- Blisters, wet sores (moist desquamation), or bleeding
- Signs of infection (pus, foul odor, fever)
- Ulcerations or wounds that do not heal in two weeks
- Any new or changing skin lesions in the treatment area months or years after therapy
Your care provider may refer you to a wound care specialist or dermatologist for complex issues.
Emotional Support and Holistic Approaches
Radiation-induced skin changes can affect not just physical comfort but also self-esteem and quality of life. A holistic plan includes:
- Regular, supportive check-ins by your oncology team
- Patient education on self-care and skin monitoring
- Access to psychological or peer support groups
- Exploring cosmetic solutions for visible changes once healing allows
- Guidance on stress reduction, lifestyle, and nutritional support to foster healing
Patients are encouraged to participate in decisions about their care, addressing personal goals and preferences along with medical recommendations.
Frequently Asked Questions (FAQs)
Q: Is it safe to use deodorants or antiperspirants during radiation?
Historically, patients were told to avoid these products. However, current evidence suggests deodorant/antiperspirant use is generally safe and may be permitted if it does not irritate the skin. Always confirm with your oncologist first.
Q: Can I swim or exercise during treatment?
Light exercise is beneficial, but avoid swimming pools, hot tubs, or lakes during radiation therapy. Chlorine and bacteria can further irritate or infect vulnerable skin.
Q: What should I do if my skin starts blistering or weeping?
Cover the area with a non-stick sterile dressing, keep it clean, and contact your healthcare team promptly for wound assessment and specialized care instructions.
Q: How long will these skin effects last?
Most acute symptoms improve within weeks after therapy ends. However, some degree of dryness, pigmentation, or sensitivity may persist for months or become permanent. Long-term care and skin protection remain important.
Q: Are there natural remedies I should try?
Always discuss any supplementary treatments with your oncology team. Some natural oils or aloe vera gels are gentle but may not be as effective as medical-grade emollients. Avoid herbal products or essential oils unless cleared by a professional, as these can cause irritation during radiation therapy.
