Skin cancer is a disease in which cells in the body grow out of control. When cancer starts in the skin, it is called skin cancer. The most common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. The two main causes of skin cancer are exposure to ultraviolet (UV) radiation from the sun and using UV tanning beds. Other factors that can contribute to the risk of skin cancer include:

• Fair skin
• A history of sunburns
• Excessive sun exposure
• Exposure to radiation
• Certain skin conditions
• A weakened immune system

UV radiation from the sun damages the DNA in skin cells, causing abnormal cells to form and grow out of control. While anyone can get skin cancer, some groups are at higher risk than others, such as people with fair skin, red or blonde hair, and blue or green eyes. To lower the risk of getting skin cancer, it is important to protect the skin from UV rays by wearing protective clothing, using sunscreen with a high SPF, and avoiding tanning beds. It is also important to report any unusual moles or changes in the skin to a doctor and to get regular skin cancer screenings.
