Summer sun increases the risk of skin cancer.
Amy Brackeen, a Dermatologist at Lubbock Dermatology and Skin Cancer Center, says to put on a sunscreen of at least SPF 30 15 minutes before you go outside.
You can also wear hats and other clothing to cover the skin that will be in the sun.
Brackeen says to reapply your sunscreen every two hours, or every 45 minutes if you get wet or sweaty.
You should also check your skin once a month for any new moles or spots or changes in your skin.
