Can i get a tan outside without getting skin cancer?

so i'm in highschool, and i'm 14, and i want to be tan over my spring break. But how much is a healthy time for me. i'm not pale white, and get tan easy, and i usually don't peal, but i don't stay out of the sun to much. i'm like medium tan to white. if that makes sence. like 10 or 20 minutes?
