How Often Should You Get a Skin Check?
Quick Answer
You should get a full-body skin exam by a dermatologist once a year. In addition, perform a thorough self-check every month at home. If you have a history of skin cancer, fair skin, many moles, or significant sun exposure, your dermatologist may recommend checks every 3-6 months.
Skin cancer is the most common cancer in the world — and also one of the most treatable when caught early. But it hides in places you'd never think to look: the soles of your feet, between your toes, behind your ears. The mole you've been ignoring might be nothing. Or it might be the one thing you really should have paid attention to.
Detailed Breakdown
A skin check is one of the simplest, fastest, and most effective cancer screenings available. A full-body exam by a dermatologist takes about 10-15 minutes, and monthly self-checks at home take even less.
Professional Skin Exams
Average risk Once a year. A dermatologist examines your entire body — scalp, face, ears, neck, chest, back, arms, hands, legs, feet, and nails. They use a dermatoscope (a magnifying tool with a light) to examine suspicious spots in detail.
High risk Every 3-6 months. You're high risk if you have:
- A personal or family history of melanoma
- More than 50 moles
- Atypical moles (dysplastic nevi)
- Very fair skin that burns easily
- A history of severe sunburns, especially in childhood
- A weakened immune system
Monthly Self-Checks at Home
Between professional exams, monthly self-checks are your first line of defense. Here's how to do a thorough one:
- Stand in front of a full-length mirror in a well-lit room
- Examine your face — including nose, lips, mouth, and ears (front and back)
- Check your scalp — use a comb to part your hair systematically, or ask a partner to help
- Inspect your hands — palms, backs, between fingers, and under nails
- Scan your arms — raise them and check all sides, including underarms
- Examine your torso — front, back (use a hand mirror), and sides
- Check your legs — front, back, and sides, including the backs of your knees
- Inspect your feet — soles, between toes, and toenails
The ABCDE Rule for Suspicious Moles
When examining moles or spots, look for these warning signs:
- A — Asymmetry: One half doesn't match the other
- B — Border: Edges are irregular, ragged, or blurred
- C — Color: Multiple colors or uneven color distribution
- D — Diameter: Larger than 6mm (the size of a pencil eraser)
- E — Evolving: Any change in size, shape, color, or symptoms (itching, bleeding)
If a mole meets even one of these criteria, have it evaluated by a dermatologist promptly.
Beyond Moles: Other Things to Watch
Skin cancer doesn't always look like a suspicious mole. Also watch for:
- A sore that doesn't heal within three weeks
- A shiny, pearly, or waxy bump
- A flat, flesh-colored or brown scar-like lesion
- A red, firm nodule
- A scaly, crusted patch on your lip, ears, or the back of your hands
- A dark streak under a fingernail or toenail
The Good News About Early Detection
When caught early, the 5-year survival rate for melanoma is 99%. When caught at a late stage, it drops to 32%. That's the difference that a simple annual skin check and monthly self-exam can make. These numbers apply to all skin tones — skin cancer occurs in every ethnicity, though it's often diagnosed later in people with darker skin.
Signs You Should See a Dermatologist Sooner
Don't wait for your annual exam if you notice:
- A mole that has changed in size, color, or shape
- A new mole that appeared suddenly, especially after age 30
- A spot that bleeds, itches, or crusts repeatedly
- A sore or wound that won't heal
- A dark line or discoloration under a nail
- Any of the ABCDE warning signs listed above
