How to Spot Early Signs of Skin Cancer During Summer

Summer is a time of increased sun exposure, outdoor activities, and cumulative UV damage—all of which can raise the risk of developing skin cancer or noticing changes in existing moles. Early detection is critical, as most skin cancers are highly treatable when caught early. At MDCS Dermatology, Gregory S. Phillips, M.D. emphasizes regular skin checks and patient education to help identify concerning changes before they progress.

Why Summer Increases Skin Cancer Risk
Ultraviolet (UV) radiation from the sun is the leading cause of skin cancer. During summer months, UV exposure increases due to:

• Longer daylight hours

• Stronger UV index levels

• More frequent outdoor activities

• Inconsistent sunscreen reapplication

• Intentional tanning or sun exposure

Even a single sunburn can increase long-term risk of skin cancer.

The ABCDE Rule: What to Watch For
One of the most important tools for identifying early melanoma is the ABCDE rule:

A – Asymmetry
One half of the mole does not match the other in shape or appearance.

B – Border
Edges may appear irregular, jagged, blurred, or poorly defined.

C – Color
Multiple shades such as brown, black, red, white, or blue within one lesion.

D – Diameter
Moles larger than about 6mm (pencil eraser size) should be evaluated.

E – Evolving
Any change in size, shape, color, elevation, or new symptoms like itching or bleeding is concerning.

Studies show that evolving changes are one of the strongest indicators of melanoma risk.

Additional Warning Signs to Watch For
Beyond the ABCDE rule, other signs may include:

• A mole that looks different from others (“ugly duckling” sign)

• A sore that does not heal

• Bleeding, crusting, or persistent irritation

• New growths on sun-exposed or protected areas

• Itching, tenderness, or pain in a lesion

Melanoma and other skin cancers can appear anywhere on the body—not just sun-exposed areas.

How to Perform a Monthly Skin Check
Dr. Gregory S. Phillips recommends monthly self-exams:

• Check your entire body in a well-lit mirror

• Don’t forget scalp, back, soles of feet, and between fingers/toes

• Take photos of moles to track changes over time

• Look for anything new, changing, or unusual

If something appears different, it is best to have it evaluated promptly.

When to See a Dermatologist
Schedule an evaluation at MDCS Dermatology if you notice:

• Any ABCDE changes in a mole

• Rapidly growing or changing lesions

• Non-healing sores

• Spots that bleed or become painful

• New pigmentation appearing later in life

Early evaluation can significantly improve outcomes and may prevent progression of skin cancer.

Skin Cancer Prevention Tips
To reduce risk during summer:

• Apply broad-spectrum SPF 30+ daily

• Reapply sunscreen every 2 hours outdoors

• Wear protective clothing and hats

• Avoid peak sun hours (10 AM–4 PM)

• Never use tanning beds

Consistent sun protection remains one of the most effective prevention strategies.
