How great does it feel to get a little sun on your skin? A good sunny day makes me want to put on some shorts and go out in the garden, down to a beach, or up to the mountains.

It also makes me head to the store for some more sunscreen. To me, loving your skin means protecting it from skin cancer and watching for signs of skin cancer.

The slip, slop, slap advice — Slip on a shirt! Slop on sunscreen! Slap on a hat! — is still the best way to prevent skin cancer.

Check Your Skin

Now that you are getting a look at your skin again as you put on shorts and sleeveless T-shirts, you may be wondering what to look for on your skin if you've had sunburns or extensive sun exposure in the past.

Skin cancer is the most common type of cancer in North America. It is more common as we age, but even teenagers can be diagnosed with melanoma, the most aggressive form of skin cancer. Fair-skinned and blue-eyed people are the most likely ones to develop skin cancer, but melanoma, basal cell, and squamous cell skin cancers can happen to anyone. So no matter how careful you are about sun exposure, it is still a good idea to know what sort of changes might require evaluation by a health care provider.

Your skin is changing all the time. Sun exposure can cause some people to develop freckles, hormone fluctuations can cause periodic acne breakouts, a new soap can cause a rash, and simply getting older causes lines and wrinkles. These are all changes that may be annoying but are benign.

When to See Your Doctor

Other changes may not be so harmless and you should check your skin for these changes once a month. Use a mirror to check difficult-to-see skin like the back of your thighs, the top of your head, or your back.

Basal cell lesions are usually pink or red areas, and squamous cell lesions are usually red and flaky areas. Both may also look like wounds that won't heal. Melanomas are usually darker, like a mole. But skin cancers do not always follow these rules.

See your doctor if you notice any of these skin conditions:

Basal and squamous cell skin cancer respond well to treatment, usually surgery, though sometimes a cream can work for some superficial types. For melanoma, the earlier it is detected and treated (surgically), the better the survival rate.

So keep loving that skin you're in and check it regularly in addition to protecting it with slip, slap, slop this summer.
