Skin cancer is one of the most common cancers in the UK, and too much sun can increase your risk. Exposure to sunlight can also have a major affect on your eyes.In 2011, around 115,000 people were diagnosed with skin cancer in the UK. More than 13,000 of these cancers were malignant melanoma, the most serious type of skin cancer. Each year, around 2,000 people die from skin cancer.Skin cancers are caused by damage from the sun’s ultraviolet (UV) rays. Sun damage doesn't just happen when you're on holiday in the sun. It can happen when you’re not expecting it, for example when you go for a walk or sit in your garden.To ensure you stay safe in the sun you are advised to follow these precautions. Spend time in the shade between 11am and 3pm. Make sure you never burn. Aim to cover up with a T-shirt, hat and sunglasses. Remember to take extra care with children. Then use factor 15+ sunscreen. Report mole changes or unusual skin growths to your GP.
