I'm sure you've been reminded countless times to wear sunscreen and you've probably been told if you don't you're going to get skin cancer. Well, I don't need to be told. I have a two inch scar on my back which is a constant reminder of how important sunscreen is. Now I'm here to let you know not only how to keep from getting cancer but how to find out when you need to get checked out.

Sun damage to the skin occurs when UVA and UVB rays hit the skin. UVB rays create the appearance of a sunburn while UVA rays cause the bulk of the damage, which include contributing to skin cancer. While staying out of the sun is the best way to avoid these rays, it's pretty unfeasable. Your best bet is to use a sunscreen that blocks both UVA and UVB rays. Apply liberally to all exposed skin and wait thirty minutes for the sunscreen to absorb. Use a sunscreen with an SPF of at least 15, anything less and you're going to get sun damage. But remember, just because you're wearing sunscreen doesn't mean you can stay out in the sun all day. A good rule to follow is multiply your SPF times 10 and that's how long you can stay under the sun. Usually any longer than that and you have a chance of getting burned. If you aren't going inside, reapply every two hours.

You've taken every precaution now. But what if you haven't always done so? Could that mole on your arm be cancerous? The best way to keep your moles in check is to remember ABCD, which can help you identify the most agressive skin cancer, malignant melanoma.

A- asymmetrical or the halves aren't identical
B- uneven borders
C- color, if it varies across the mole or if there is red or blue there that's a warning sign
D- diameter is larger than 6mm (bigger than a pencil eraser)

If you have just one of these you need to see a dermatologist as soon as possible. The sooner melanoma is caught, the better the survival rate.

So now you know. Go out there and enjoy spring break. But remember: tan now, scar later.
