Skin Changes During Leukemia Treatment: Causes and Management

Skin changes are a common side effect during leukemia treatment. Let me explain what causes them and how you can manage them effectively.

What Causes Skin Changes During Treatment

Skin changes during leukemia treatment happen for several reasons:

Direct Effects of Chemotherapy Chemotherapy drugs work by targeting rapidly dividing cells—which is exactly what cancer cells do. Unfortunately, your skin cells also divide quickly, especially in certain areas. When chemotherapy affects healthy skin cells, it can cause redness, irritation, dryness, and sensitivity.

Hand-Foot Syndrome (Palmar-Plantar Erythrodysesthesia) One specific skin condition called hand-foot syndrome is a common side effect of certain chemotherapy drugs. According to the NCCN Guidelines for Patients, this occurs when "small amounts of chemotherapy leak out of very small blood vessels called capillaries in the palms of the hands and soles of the feet." This causes:

• Redness and swelling
• Pain or tenderness
• Sometimes blistering

Other Causes of Skin Changes

• Weakened immune system making you more prone to infections
• Allergic reactions to medications
• Dry skin from dehydration or treatment effects
• Sensitivity to sun exposure

How to Manage Skin Changes

For Hand-Foot Syndrome and General Dryness

Moisturize regularly: According to NCCN Guidelines, you should "apply moisturizer or lotion" to protect your hands and feet. This is one of the most important preventive steps.

Specific care tips:

• Use thick creams or ointments (not just lotions) on affected areas
• Apply moisturizer while skin is still slightly damp after bathing
• Avoid harsh soaps—use gentle, fragrance-free cleansers
• Keep hands and feet cool when possible
• Wear soft, breathable clothing and comfortable shoes

For Redness and Irritation

• Avoid tight clothing that rubs on affected areas
• Protect your skin from direct sunlight (use SPF 30+ sunscreen)
• Avoid extreme temperatures (very hot baths or showers can worsen irritation)
• Don't use products with alcohol, perfumes, or dyes
• Avoid chlorine pools if you have open areas or significant irritation

For Infections or Severe Changes

• Watch for signs of infection: increasing redness, warmth, pus, or fever
• Keep skin clean and dry
• Avoid picking at or scratching affected areas
• Report any worsening symptoms to your care team immediately

Important Questions to Ask Your Care Team

Since skin changes vary by person and by specific treatment, ask your oncologist:

1. Which skin side effects am I most likely to experience with my specific treatment plan?
2. Are there prescription creams or medications I should use preventively?
3. When should I contact you about skin changes—what symptoms are concerning?
4. Are there any products I should avoid during treatment?
5. Should I see a dermatologist (skin specialist) if skin changes develop?

When to Contact Your Healthcare Team

Reach out to your care team if you experience:

• Severe pain in your hands or feet
• Signs of infection (increasing redness, warmth, drainage, fever)
• Blistering or open sores
• Skin changes that interfere with daily activities
• Allergic reactions (hives, severe itching, difficulty breathing)
