Understanding Melanoma

Melanoma is a type of skin cancer that begins in melanocytes—the pigment-producing cells in your skin. While it's less common than other skin cancers, melanoma is far more likely to grow and spread if not caught early.

The good news? Most melanomas are caused by ultraviolet (UV) radiation—meaning most are preventable with the right habits.

Why Melanoma Prevention Matters for You

• Once melanoma spreads, it's difficult to treat: Early prevention dramatically lowers risk.
• Skin is your largest organ: Protecting it boosts overall wellness and slows visible aging.
• Prevention is easier (and cheaper!) than cure: Most prevention tips are low-cost or free.

• Myth 1: “I don't burn, so I can't get melanoma.”
  Reality: Melanoma can develop in anyone, regardless of skin tone or whether you sunburn easily.
• Myth 2: “A tan protects me from skin cancer.”
  Reality: Tanning is a sign of skin damage. Any change in skin color from the sun or tanning beds raises your risk.
• Challenge: “It's inconvenient to always cover up or apply sunscreen.”
  With modern products, prevention can fit easily into your routine with little hassle.
• Myth 3: “Skin cancer only happens to older people.”
  Reality: Melanoma is one of the most common cancers in people under 30—especially young women.

1. Make Sun Protection a Daily Habit (Not Just at the Beach!)

• Apply broad-spectrum sunscreen (SPF 30+) to all exposed skin, every day—even in winter, even when it’s cloudy.
• Wear protective clothing: Long sleeves, wide-brim hats, sunglasses (look for UV400 or “100% UV protection” labels).
• Seek shade between 10 a.m. and 4 p.m., when UV rays are strongest.

2. Avoid Tanning Beds Completely

• Just one indoor tanning session before age 35 boosts your risk by up to 75% (CDC research).

3. Regular Skin Self-Exams

• Check your skin monthly—look for new moles or spots or any changes in size, shape, or color. Use the ABCDE rule:
  • Asymmetry
  • Border irregularity
  • Color that is not uniform
  • Diameter >6mm
  • Evolving size, shape, or color

4. Get Annual Skin Checks With a Dermatologist

• Especially important if you have fair skin, a personal/family history of skin cancer, or many moles.

5. Be UV-Aware Even on Cloudy Days or Through Windows

• Up to 80% of the sun’s rays can penetrate clouds.
• UV rays pass through car and office windows—consider window protection or applying sunscreen.

• Choose Mineral Sunscreens: Zinc oxide and titanium dioxide are less likely to irritate sensitive skin and provide broad-spectrum protection. (Journal of the American Academy of Dermatology)
• Reapply Sunscreen Every 2 Hours—Or After Swimming/Sweating. Most people apply only 25–50% of the recommended amount. Use a shot-glass-sized (about 1 oz) amount for full body coverage.
• Don’t Forget “Non-Obvious” Spots: Ears, tops of feet, scalp, and backs of hands are easy to miss and common sites for melanoma.
• Get Vitamin D from Diet/Supplements, Not Sun: It's a myth that sun exposure is your only choice. Foods and safe supplements offer an alternative without the UV damage.

Free Habits

• Check local UV index each morning (many weather apps provide this)
• Seek shade when outdoors
• Wear clothes you already own: long sleeves, pants, hats
• Do self-skin checks in the shower or when changing

Paid Tools & Products

• High-quality Sunscreens: Broad-spectrum, SPF 30+, water-resistant (e.g., Neutrogena, EltaMD, La Roche-Posay, Supergoop, Blue Lizard)
• UPF Clothing: Sun-protective shirts/hats (brands like Coolibar and Columbia offer stylish options)
• Sunglasses with 100% UV protection
• Mirror or skin-check app: Apps like Miiskin help track mole changes, while a magnifying mirror aids closer checks

• Susan, age 32: Grew up as a swimmer, rarely used sunscreen. After a mole changed, her dermatologist caught an early melanoma. Now, Susan applies SPF daily and wears long sleeves outdoors, enjoying her routines without anxiety.
• Mike, construction worker: Used to skip sunscreen because it felt greasy. Switched to a mineral, matte-finish sunscreen and now keeps a bottle in his truck—no more burns, and he feels healthier.
• Lila, mother of three: Made sun hats and SPF clothing part of their family’s pool days. Her kids now remind her about “sunscreen time”—it’s a new healthy habit for all.

• Skipping sunscreen "just this once." Consistency is key—UV damage adds up over time.
• Assuming "waterproof" sunscreen lasts all day. Reapply after swimming or sweating heavily.
• Ignoring spots that “just don’t look right.” If in doubt, check it out—skin cancers can look different on everyone.
• Forgetting indoor UV exposure. You get UV rays through windows and during daily commutes.
• Using expired sunscreen. Check those dates—most lose effectiveness after 1–3 years.
