Slather, Swim, Repeat: Outsmarting Skin Cancer This Summer
Embracing Summer Safely
As summer arrives, bringing with it the allure of sun-soaked beaches and refreshing swims, people eagerly head outdoors to bask in the warmth. However, amidst the pursuit of the perfect tan, the significance of sun safety is frequently overshadowed. Skin cancer, as noted by the Centers for Disease Control (CDC), stands as the most prevalent form of cancer in the United States, yet it remains largely preventable.
The statistics are staggering: one in five Americans is expected to develop skin cancer over their lifetime, according to the American Academy of Dermatology. As the summer sun reaches its zenith and UV indexes climb, the call to prioritize skin protection grows more urgent.
The Imperative of Sun Protection
Dr. Rachel Hill from Daniel Island Dermatology emphasizes the critical nature of sun protection. She describes ultraviolet radiation as a proven carcinogen, highlighting that skin cancer is a profound public health concern in the U.S., with melanoma—its deadliest variety—resulting in approximately 9,000 fatalities annually.
While completely avoiding the sun isn't feasible, adopting effective sunscreen habits is a formidable line of defense. Not every sunscreen is made equal, which makes choosing the right one crucial.
Choosing the Right Sunscreen
The best sunscreen for daily use, according to Hill, is broad-spectrum with at least SPF 30, offering protection against both UVA and UVB rays. For those engaging in water-based activities or sports, a water-resistant sunscreen should be sought, necessitating reapplication every two hours or post-swim.
Tinted sunscreens containing iron oxides are recommended for those wishing to prevent dark spots due to their ability to protect against visible light as well as ultraviolet radiation. Hill insists the optimal sunscreen is one you will use consistently.
Practical Tips for Families
Melanie Hart, a Daniel Island resident, echoes Hill's advice. Her family's routine involves applying Blue Lizard sunscreen due to its suitability for sensitive skin. She always carries a stick version for easy reapplication on her children’s faces, ingraining the importance of sunscreen as a family practice.
Sunscreens can generally be categorized into two main types: physical (mineral) and chemical. Physical sunscreens, containing zinc oxide or titanium dioxide, are ideal for sensitive skin or young children due to their dual function of deflecting and absorbing the sun's rays. Chemical sunscreens, while lightweight and broad in protection, often spark debate over their ingredients. Nevertheless, Hill clarifies that there is no scientific foundation for the belief that sunscreens cause skin cancer—a misconception that can deter effective sun protection.
International Sunscreen Innovations
Some are wary of American sunscreen formulations. Hill points out that countries like those in Europe and Asia may present more advanced alternatives, with newer chemical filters like bemotrizinol awaiting FDA approval in the U.S.
Beyond Sunscreen: Protective Habits
Effective sun protection extends beyond sunscreen. Hill advocates for lifestyle changes such as wearing a hat, sunglasses, sun-protective clothing, and seeking shade, particularly during peak sun intensity between 10 a.m. and 4 p.m. Long-sleeved bathing suits or rash guards can significantly reduce the amount of sunscreen needed while offering additional protection.
For individuals residing in regions with a subtropical climate, these precautions are even more critical. Terry Wright, a Clements Ferry local and enthusiastic boater, recounts how a brush with a precancerous mole altered his approach to sun safety. His experience underscores the importance of comprehensive protection, from wearing long-sleeved clothing to frequent sunscreen reapplication.
Addressing Neglected Areas
Even diligent sunscreen users may overlook vulnerable areas such as the ears, scalp, and tops of feet. Hill advises on not neglecting lips, for which an SPF 30 lip balm should be reapplied after eating and drinking. Other often-missed spots include the back of the neck, hands, and around the eyes, where UV-protective sunglasses or mineral sunscreen can be beneficial.
For swimmers and those with exposed scalps, specific attention is required to protect these susceptible regions with sunscreen.
Vigilance in Detection: The ABCDEs of Melanoma
Skin cancer prevention also involves regular inspection for signs of melanoma. Knowing the ABCDEs of melanoma—Asymmetry, irregular Borders, varied or changing Color, Diameter over 6 millimeters, and Evolution over time—can be life-saving. Symptoms like itching, bleeding, or pain should prompt a dermatology consultation.
Regular skin checks are recommended, particularly for adults. Those with numerous moles should begin annual checks between ages 20 and 25, and generally every one to two years thereafter. An increased frequency is advised for individuals with personal or family histories of skin cancer.
Protecting the Youth
Children's delicate skin warrants particular attention, as early sun damage can produce long-term effects. Apply sunscreen generously 15 minutes before sun exposure, avoid peak hours, and dress them in wide-brimmed hats, sunglasses, and lightweight, long-sleeved clothing. Mineral-based sunscreens with SPF 30 or higher are advised until they consistently engage in these protective habits unprompted.
Engaging children by explaining the rationale behind these measures can instill an understanding of the lasting importance of sun protection.
A Year-Round Commitment
Hill reminds us that sun protection is a year-round commitment, not confined to beach days alone. Consistent application of sunscreen, appropriate clothing, and seeking shade contribute significantly to long-term health.
The next time sunshine beckons, remember to prioritize sun protection with the simple yet powerful act of applying sunscreen. Assist your future self in cherishing both the summer sun and enduring wellness.
