May is Skin Cancer Awareness Month: a time to focus on education, prevention, and early detection of the most common cancer in the United States. While that statistic may sound concerning, there’s also reassuring news—skin cancer is one of the most preventable cancers and, when caught early, highly treatable.
What is skin cancer?
Skin cancer occurs when skin cells grow abnormally, most often due to exposure to ultraviolet (UV) radiation from the sun or tanning beds. The most common types include basal cell carcinoma and squamous cell carcinoma, which are typically slower growing, and melanoma, which is more aggressive. Melanoma can spread quickly, but when detected early, it is highly treatable.
What should you look for?
Being familiar with your skin is one of the most powerful tools for early detection. Pay attention to any new, changing, or unusual spots. A mole that evolves in size, shape, or color; a spot that doesn’t heal; or a lesion that looks different from others on your body can all be warning signs.
Many providers use the “ABCDE rule” as a general guide—looking at asymmetry, irregular borders, uneven color, larger diameter, and evolution over time. Even without memorizing each detail, the key is simple: if something looks off, it’s worth having it checked.
Who is most at risk?
Skin cancer can affect anyone, but certain factors can increase your risk. These include having fair skin, a history of sunburns, prolonged sun exposure without protection, tanning bed use, or a personal or family history of skin cancer.
Even if you don’t consider yourself high risk, consistent sun protection and regular skin checks are essential for everyone.
How can you protect your skin?
Protecting your skin doesn’t have to be complicated—it comes down to building a few consistent habits. Wearing a broad-spectrum SPF 30 or higher every day is one of the most effective ways to prevent sun damage. Reapplying sunscreen when you’re outdoors (every 2 hours), seeking shade during peak sun hours, and incorporating protective UPF clothing as well as hats and sunglasses can further reduce your exposure. Avoiding tanning beds is also crucial, as they significantly increase skin cancer risk.
Why do annual skin checks matter?
Even with the best care at home, professional skin exams play a critical role in early detection. A board-certified dermatologist is trained to identify subtle changes that may not be obvious to the untrained eye and can catch potential concerns before they progress.
If you notice anything new or changing, don’t wait for your annual visit. Getting it evaluated early can make all the difference.
How can you take action this month?
