Monthly Skin Self-Exam Guide: What Dermatologists Want You to Look For (and What to Ignore)

Regular skin checks are an important part of staying on top of your health. A monthly skin self-exam helps you spot changes early—including potential warning signs of skin cancer—while also avoiding unnecessary worry over harmless marks. This skin self-exam guide will walk you through exactly what dermatologists want you to look for and what you can safely ignore.

Why a Monthly Skin Self-Exam Matters

• Early detection of skin cancer dramatically improves treatment success.
• You learn what "normal" looks like on your own body, so changes stand out.
• You build a habit that only takes 5–10 minutes each month.
• It's free, noninvasive, and can be done at home.

How to Prepare

1. Find a well-lit space
   A full-length mirror plus a handheld mirror and bright natural or white light work best.

2. Gather tools

   • Handheld mirror
   • Full-length mirror
   • Hairdryer (for checking scalp)
   • Notebook or smartphone (to photograph and record findings)

3. Wear minimal clothing
   A swimsuit or underwear is fine. You want to see as much skin as possible.

4. Set a reminder
   Pick a day each month—like the first Sunday—and put it on your calendar.

The Step-By-Step Skin Self-Exam Guide

1. Head and Face

• Hairline and scalp: Use a hairdryer to move hair aside. Look for new bumps or patches.
• Ears: Check front, back, and folds for rough or scaly areas.
• Face: Scan your forehead, nose, cheeks, and around your lips for any moles that have changed shape or color.

2. Neck, Chest, and Torso

• Front torso: Arms raised, inspect sides of your chest and rib cage.
• Under breasts (if applicable): Look for redness, scaling, or crusting.
• Midline and back: Use the full-length mirror and handheld mirror together.

3. Arms and Underarms

• Armpits: Lift arms and look for bumps or spots.
• Upper and lower arms: Rotate arms slowly to see all sides.
• Hands, fingers, and nails: Check between fingers, under nails, and around cuticles.

4. Back and Buttocks

• Upper and lower back: Use the mirrors or ask someone you trust for help.
• Buttocks and genital area: Look carefully in mirror or with assistance to spot any unusual marks.

5. Legs and Feet

• Thighs and calves: Sit and face each mirror to inspect the front and back.
• Feet: Look at soles, heels, and between toes.
• Toenails: Check for streaks of dark pigment or discoloration.

What Dermatologists Want You to Look For

Dermatologists often use the ABCDE rule to flag concerning moles or spots:

• A – Asymmetry
  One half doesn't match the other.

• B – Border
  Irregular, notched, or scalloped edges.

• C – Color
  Multiple colors (brown, black, pink, red, white, or blue) in one lesion.

• D – Diameter
  Larger than 6 mm (about the size of a pencil eraser), though smaller ones can still be concerning.

• E – Evolving
  Any change in size, shape, color, or symptoms (itching, bleeding, pain).

Beyond ABCDE, also watch for:

• New or changing itchy or bleeding spots.
• Crusty or scaly patches that don't heal in 2–4 weeks.
• Sudden appearance of multiple small reddish or brown spots (could be angiomas).
• Any lump under the skin that grows or hurts.

What You Can Generally Ignore

• Freckles and sunspots that have stayed the same for years.
• Tiny milia (small white bumps) on eyelids—common and benign.
• Skin tags in areas of friction (neck, underarms, groin) that haven't changed.
• Cherry angiomas (small bright-red dots) that stay stable over time.
• Moles with smooth, regular borders and uniform color that aren't evolving.

If a spot truly looks and feels the same year after year, it's almost always harmless. Still, take a quick look during your monthly check.

---

Documenting Your Findings

• Take photos of any spots you're monitoring.
• Date your photos and note the location on your body.
• Keep a simple log: "April 1: 3×4 mm mole on left calf; uniform light brown."

Review your photos each month to catch even subtle changes.

When to Speak to a Doctor

While self-exams are invaluable, they're not a substitute for professional care. Speak to a doctor right away if you notice:

• Any spot with irregular borders, multiple colors, or rapid changes.
• Persistent pain, bleeding, or crusting in one area.
• A new lump under the skin that grows over weeks.

If you experience any other troubling symptoms—such as unexplained weight loss or swollen lymph nodes—reach out to your healthcare provider promptly.

Building a Healthy Habit

• Keep your skin self-exam guide on your bathroom mirror or phone reminders.
• Combine your exam with another monthly task (e.g., paying rent).
• Encourage family members or friends to do the same, especially if there's a history of skin cancer in your family.
