Sunburn & Cancer Risk: What Seniors Need to Know

As we get older, it's easy to think that the sun damage from our younger years is already done. But dermatologists say that's only part of the story. While decades of UV exposure can increase your risk of skin cancer, protecting your skin today still makes a meaningful difference. Sun damage continues to accumulate throughout life, and reducing additional exposure may help lower your future risk.

Why Sunburn Matters More Than You Think

A sunburn isn't just a temporary inconvenience. It happens when ultraviolet (UV) rays damage the DNA inside your skin cells. Although your body repairs much of that damage, some changes can remain. Over many years, those changes may contribute to skin cancer, including melanoma, the most serious form of the disease.

Many people diagnosed with melanoma are in their 60s or older. That's because skin damage often develops slowly, taking years—or even decades—to become noticeable.

It's Never Too Late to Protect Your Skin

Even if you spent summers sunbathing or rarely wore sunscreen when you were younger, today's habits still matter.

As skin ages, it becomes thinner and less able to repair itself efficiently. Your immune system also changes with age, making it more important than ever to limit unnecessary UV exposure. Preventing future sunburns may help reduce additional damage and support healthier skin.

Simple Ways to Reduce Your Risk

You don't have to stay indoors to enjoy life. A few practical habits can significantly reduce your UV exposure:

• Apply a broad-spectrum sunscreen with SPF 30 or higher every day you'll be outside.

• Reapply sunscreen every two hours, or sooner if you're swimming or sweating.

• Wear a wide-brimmed hat, UV-blocking sunglasses, and lightweight long sleeves when practical.

• Seek shade during the strongest sunlight, typically between 10 a.m. and 4 p.m.

• Remember that UV rays can reflect off water, sand, concrete, and snow—even on cloudy days.

Know the Warning Signs

Early detection greatly improves treatment outcomes. Schedule an appointment with a healthcare provider if you notice:

• A new mole or spot that looks different from others.

• A mole that changes in size, shape, or color.

• A sore that doesn't heal.

• A spot that bleeds, crusts, itches, or becomes painful.

Don't Forget Your Eyes

Your skin isn't the only part of your body affected by UV rays. Long-term sun exposure has also been linked to cataracts and other eye conditions. Wearing sunglasses that block 100% of UVA and UVB rays can help protect your vision.

The Bottom Line

No one can erase years of past sun exposure, but every step you take now can help protect your skin in the years ahead. Daily sun protection, regular skin checks, and paying attention to new or changing spots are simple habits that can make a lasting difference.
