A must-have summer "accessory" goes with everything in your wardrobe.
Whether it's catching a wave or takin' a dip - working outside, or working out, we're exposing ourselves to a killer every single summer day.
Grant Grussing is one of 53,000 men and women who'll be diagnosed with melanoma this year. It started out like this on his leg, would you know what to look for?
Check out your moles for the ABC and D's of melanoma.
First, is your mole asymmetric, with one side bigger than the other? Check the border for jagged edges, then move on to the color. Does the mole have different colors, and is it larger than 6 millimeters in diameter?
If you answered yes to any of these, see a doctor. And even if you don't have issues now, protect yourself before you head outside. Jane Houlihan, of the environmental working group says any SPF over 30 gives only a few more percentage points worth of protection. But never wear anything under SPF 15.
"What it doesn't tell you about the other side of sun damage which is UVA radiation. And that's linked to skin damage, aging and skin cancer too," Houlihan said.
As for Grant, he beat his battle with the sun.
"I'm good to go. 100 percent."
