As summer heats up, many of us are eager to spend more time outdoors soaking in the sunshine. But with those sunny days comes a critical health reminder: skin cancer is the most common cancer in the United States, and most cases are preventable.
At Princeton Longevity Center, we emphasize year-round prevention, and summer is the perfect time to refresh your skin safety strategy. Here’s how to protect your skin and your long-term health while still enjoying the season.
Understanding Skin Cancer Risks
Ultraviolet (UV) radiation from the sun (and tanning beds) is the primary environmental risk factor for skin cancer. Risk is especially high between 10 a.m. and 4 p.m., when UV rays are strongest.
Additional risk factors include:
- Fair skin, light hair, and light eyes
- History of sunburns or excessive sun exposure
- Family or personal history of skin cancer
- Use of immunosuppressive medications
- Genetic mutations (such as CDKN2A, MC1R, or BAP1) linked to melanoma
Smart Sun Protection Strategies
- Protecting your skin doesn’t mean avoiding the sun entirely, it means being smart about exposure.
- Avoid peak UV hours: Plan outdoor activities in early morning or late afternoon when UV rays are less intense.
- Use sunscreen daily: Choose a broad-spectrum sunscreen with SPF 30 or higher. Apply generously to all exposed skin at least 15 minutes before going outside.
- Reapply every 2 hours and after swimming or sweating even if the sunscreen is water-resistant.
- Wear protective clothing: Lightweight, long-sleeved UV-protective shirts, wide-brimmed hats, and UV-blocking sunglasses can reduce exposure.
- Seek shade whenever possible, especially during midday hours.
Know the ABCDEs of Melanoma
Early detection is key. When performing self-skin checks, watch for these warning signs:
- Asymmetry: One half doesn’t match the other
- Border: Irregular, scalloped, or poorly defined edges
- Color: Varies in shades of tan, brown, black—or includes red, white, or blue
- Diameter: Larger than 6mm (about the size of a pencil eraser)
- Evolving: Changing in size, shape, or color over time
If you notice any of these signs, see a dermatologist promptly.
Annual Dermatology Exams Are a Must
Even if you don’t see any concerning spots, we recommend an annual full-body skin exam with a board-certified dermatologist. A trained eye can detect early skin cancers before they become dangerous. If you have a personal or family history of melanoma, you may need more frequent monitoring.
The Role of Genetic Testing
For individuals with a family history of melanoma or multiple atypical moles, genetic screening may be warranted. Tests can identify high-risk mutations, prompting closer dermatologic surveillance, lifestyle changes, and even inclusion in research trials.
Ask your Princeton Longevity provider if a genetic assessment is right for you.
Don’t Forget Your Eyes
Skin cancer can also develop on the eyelids or within the eyes. Annual comprehensive eye exams, especially for those with high UV exposure, can detect ocular melanoma and other sun-related changes early. Wearing UV-blocking sunglasses helps protect this delicate area year-round.
Your Skin Deserves a Long, Healthy Life
Summer can and should be enjoyed safely. With a proactive approach, the right protection, and regular screenings, you can dramatically reduce your risk of skin cancer while still embracing the outdoors.
At Princeton Longevity Center, we help you build a comprehensive prevention plan tailored to your lifestyle and risk factors. From genetic testing to dermatologic referrals and annual wellness assessments, we’re here to keep your skin and your whole body healthy for the long run.
Enjoy the sunshine, but play it safe.
