Skin cancer is the most common form of cancer in the United States, with 1 in 5 Americans developing it in their lifetime. Fortunately, when diagnosed and treated early, skin cancer can almost always be cured.
Skin Cancer Basics
Skin cancer is an abnormal growth of skin cells. It can affect people of all colors and races, but is more likely to occur in those with fair skin. The two most common types of skin cancer are basal cell and squamous cell carcinomas. Both cancers are highly curable, though if left untreated, can cause serious damage and disfigurement. Melanoma is the third most common—and deadliest—skin cancer. Melanoma generally develops in a mole or appears as a new dark spot on the skin.
The majority of skin cancers develop due to overexposure to ultraviolet (UV) light. UV light is a type of radiation produced by the sun, tanning beds and sunlamps. It is invisible to the human eye, but can penetrate and damage skin cells. Minimizing exposure to harmful UV rays is key in skin cancer prevention.
Reduce Your Risk
- Stay out of the sun as much as possible.
The sun’s rays are strongest between 10am and 2pm, so seek shade during these hours or protect your skin with clothing. Consider wearing long sleeves, pants, sunglasses and a wide brim hat. Be especially aware if you’re near water, sand, or snow. These surfaces can reflect and intensify the damaging effects of the sun.
- Always wear sunscreen.
It doesn’t matter what time of year it is or what the weather is like. If you’re spending time outdoors, it’s important to apply sunscreen to all exposed skin. Choose a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher. Apply it every 2 hours and after you swim or sweat.
- Check your skin regularly for changes.
