Is Spicy Food Safe for People with Melanoma?

Most people living with melanoma can eat spicy food safely. There is no high‑quality evidence that spicy foods (like chili peppers or capsaicin) increase melanoma risk or worsen outcomes. Nutrition guidance during and after cancer treatment focuses more on overall diet quality, maintaining weight, food safety, and symptom management rather than forbidding spices. ^{[1] [2]}

What We Know About Spicy Foods and Cancer

• Melanoma-specific risk: Research on melanoma centers on ultraviolet exposure and certain clinical factors; dietary spice intake is not identified as a proven melanoma driver. Key risk factors for melanoma relate to sun exposure and UV protection, not spicy foods. ^[3]
• Capsaicin and cancer, generally: Evidence linking spicy foods or capsaicin to cancer is mixed and mainly concerns gastrointestinal cancers, not melanoma. Spicy peppers are classified as a limited evidence risk for stomach cancer in some reports, meaning data are not strong or conclusive. ^{[4] [5] [6] [7]}

Eating During Melanoma Treatment

If you’re receiving therapy (surgery, immunotherapy, radiation, or chemotherapy), the priority is adequate calories, protein, and hydration to maintain strength and weight. ^{[2] [8]}

• Tolerability matters: Some people experience nausea, mouth soreness, reflux, or taste changes during treatment. In those cases, very spicy or acidic foods can irritate and might be better limited temporarily. ^{[9] [10]}
• Practical tip: On infusion or “treatment days,” many centers advise lighter, bland meals to reduce nausea (for example, yogurt, toast, or cereal), and to avoid greasy or very spicy foods if they worsen symptoms. ^{[9] [11]}
• Flavor solutions: If food tastes bland, it’s acceptable to use herbs, mild spices, marinades, and sauces to improve appetite, as long as they don’t irritate your mouth or stomach. ^[12]

Food Safety Over Food Spice

Treatment can sometimes weaken immunity. Food safety is more important than whether a dish is spicy. ^[13]

• Avoid raw or undercooked meats, fish, eggs, and raw sprouts.
• Keep perishable foods at safe temperatures and respect “use by” dates.
• Spice level does not increase infection risk; unsafe food handling does. ^[13]

Overall Diet Pattern That Supports Skin Health

While no single food prevents melanoma, a balanced, plant‑forward pattern (similar to Mediterranean eating) rich in vegetables, fruits, legumes, whole grains, nuts, olive oil, and fish supports general health and may be associated with lower skin cancer risk in some observational research. Nutrients like carotenoids (e.g., lycopene in tomatoes) appear promising, though evidence varies. ^[14]

When to Limit Spicy Foods

Consider cutting back if you have:

• Mouth sores, gastritis, reflux, or diarrhea during treatment, because spice can worsen irritation. ^[9]
• Taste changes or nausea, where bland, cool foods may be easier. ^{[10] [11]}

These adjustments are symptom‑based and temporary, not melanoma‑specific rules. ^{[9] [10]}

Bottom Line

• Spicy food is generally safe for people with melanoma. There is no strong evidence that spice affects melanoma risk or recurrence. ^[3]
• Prioritize balanced nutrition, weight maintenance, and food safety during treatment. Adjust spice only if it worsens your symptoms. ^{[2] [8] [13]}
• Use herbs and mild spices to keep food enjoyable and support appetite, as tolerated. ^[12]

Helpful Tips

• If spicy foods bother you, try milder seasonings (herbs, garlic, ginger), or serve foods lukewarm or cool to reduce irritation. ^[10]
• Work with an oncology dietitian for a personal plan; nutrition counseling is part of many melanoma programs. ^[1]
