(Undated) -- This week is National Safe Sun week ahead of the Memorial Day Holiday and an Iowa doctor has some tips to prevent sun damage that can lead to cancers for those planning to spend the weekend outside.
Dr. Marta Van Beek, University of Iowa Hospitals and Clinics, says the skin cancer patients they see are getting younger.
She says "We used to see most of our skin cancer patients usually in their 60s and 70s. Now it is not uncommon for us to see people who get skin cancer in their 20s and 30s."
She recommends people use at least one ounce of SPF 30 or greater at all times when they're outside regardless of their age and apply it at least 15 minutes before sun exposure.
Sunscreen should be reapplied every two hours or more often if doing activities like swimming or golfing.
According to the CDC, skin cancer is the most prevalent type of cancer in the U.S.
