Your skin remembers every sunburn, every long afternoon outside, and every time sunscreen was an afterthought. Preventing skin cancer requires daily thought to sun safety, as UV radiation is the primary cause of most skin cancers including melanoma, an aggressive form of skin cancer.
To protect your skin, apply a broad-spectrum sunscreen with an SPF of 30 or higher every day to all exposed areas, and reapply it every two hours – or after swimming or sweating. Beyond sunscreen, you can reduce your risk by seeking shade during peak sun hours (10a to 4 p), wearing UPF-rated clothing, and choosing wide-brimmed hats and UV-blocking sunglasses. You can explore daily UV index forecasts on many weather apps and websites, making it easy to check sun exposure risk before spending time outdoors.
In addition to daily defense, early detection is critical for successful treatment. Routinely examine your skin from head to toe to catch any new or changing spots early. When checking your skin, use the ABCDE guide to look for:
- Asymmetry (one half does not match the other)
- Border irregularity (ragged or notched edges)
- Color variation (different shades or patchy colors)
- Diameter (larger than a pencil eraser)
- Evolving (a mole that changes in size, shape, or color, or begins to bleed or itch)
For a visual guide on what to look for and how to perform a self-exam, visit the American Academy of Dermatology Association (AAD).
