Essential Guide to Skin Self-Examination: What to Look for Between Dermatology Visits

Why Skin Self-Examinations Matter

Regular visits to your dermatologist are crucial for maintaining healthy skin, with full professional skin exams recommended annually. However, the months between these appointments present an important opportunity for you to become your skin's first line of defense. Performing monthly skin self-examinations can help detect changes early, potentially catching skin cancer and other serious conditions when they're most treatable.

Being familiar with your skin's normal appearance – including existing moles, freckles, birthmarks, and other features – enables you to notice subtle changes that might otherwise go undetected. While many skin changes are harmless, some can signal serious conditions like melanoma, basal cell carcinoma, or squamous cell carcinoma.

How to Perform a Thorough Skin Self-Exam

Conducting an effective self-examination requires good lighting, a full-length mirror, and a hand mirror for hard-to-see areas. Choose a well-lit room and examine your entire body systematically, starting from your scalp and working downward.

Step-by-Step Examination Process

Begin by examining your face, including your nose, lips, mouth, and ears. Don't forget to check behind your ears and along your hairline. Move to your neck, chest, and torso, lifting your arms to examine your underarms and sides. Use the hand mirror to check your back, shoulders, and the back of your neck.

Continue with your arms, examining both the tops and undersides, including between your fingers and under your nails. For your lower body, sit down to thoroughly examine your legs, including your thighs, shins, calves, and ankles. Finally, check your feet, including the soles, between your toes, and under your toenails.

Warning Signs: What to Look for During Your Self-Exam

The ABCDE Rule for Evaluating Moles

Dermatologists recommend using the ABCDE criteria when examining moles and other pigmented spots:

Asymmetry: One half of the mole doesn't match the other halfBorder: Edges are irregular, notched, or blurredColor: Color is not uniform throughout or has multiple colorsDiameter: Larger than 6mm (about the size of a pencil eraser)Evolving: Any changes in size, shape, color, or texture

Changes in Existing Marks and Moles

Pay special attention to any existing moles, freckles, or birthmarks that change in appearance. Benign moles typically remain stable throughout your life, maintaining consistent color, size, and shape. If you notice a previously stable mark becoming darker, lighter, or developing multiple colors, this warrants professional evaluation.

Size changes are equally important. A mole that grows larger, becomes raised when it was previously flat, or develops an irregular border should be examined by a dermatologist. Additionally, any mole that becomes itchy, tender, or starts bleeding requires immediate medical attention.

Non-Healing Wounds and Sores

Healthy skin has remarkable healing abilities, with minor cuts and scrapes typically healing within days to weeks. Persistent wounds that fail to heal properly can indicate several serious conditions, including skin cancer.

Be particularly concerned about sores that repeatedly scab over and reopen, especially in sun-exposed areas like your face, ears, neck, or hands. Basal cell and squamous cell carcinomas often present as non-healing wounds that may bleed easily or develop crusty surfaces.

New or Unusual Skin Discoloration

New patches of discolored skin deserve careful attention, especially if they appear suddenly or in areas with previous sun damage. Dark patches, red scaly areas, or white spots that weren't previously present should be documented and monitored for changes.

Pay particular attention to areas that have experienced significant sun exposure or previous sunburns. Even sunburns from years or decades ago can contribute to skin cancer development, making these areas higher risk for future problems.

Special Considerations for High-Risk Areas

Sun-Exposed Regions

Areas that receive regular sun exposure – including your face, neck, ears, shoulders, and hands – require extra attention during self-examinations. These regions are most susceptible to UV damage and subsequent skin cancer development.

Previously Sunburned Areas

Document any areas where you've experienced severe sunburns, even those from childhood or young adulthood. These areas remain at elevated risk for developing skin cancer throughout your lifetime, making regular monitoring essential.

When to Contact Your Dermatologist

While monthly self-examinations are valuable, they don't replace professional dermatologic care. Schedule an appointment if you discover any concerning changes, including new growths, changing moles, persistent sores, or unusual skin discoloration.

Additionally, maintain your annual professional skin screening even if your self-examinations reveal nothing concerning. Dermatologists have specialized training and tools that can detect changes you might miss during self-examination.
