NATIONWIDE — It’s National Melanoma Day — The American Academy of Dermatology created the day designed to raise awareness of the disease.

Melanoma is one of the most deadly forms of skin cancer, but it doesn't stop at one day — the whole month of May is designated to it as Skin Cancer Awareness Month.

With summer approaching, the medical community wants to remind people to be careful in the sun and tanning in general.

What causes melanoma?

According to the American Cancer Society, many risk factors for melanoma have been found, but it’s not always clear exactly how they might cause cancer.

For example, while most moles never turn into a melanoma, some do. Researchers have found some gene changes inside mole cells that may cause them to become melanoma cells. But it’s still not known exactly why some moles become cancerous while most don’t.

The American Academy of Dermatology advises that you watch skin spots for these features:

A: Asymmetry

B: Border irregularity

C: Color changes

D: Diameter

E: Evolving

How do I make sure I don't miss anything?

• Stand in front of a full length mirror in a well lit room.
• Start at the top and work your way down your body.
• Begin by using a brush or hairdryer to part your hair into sections so that you can check your scalp.
• Move to your face and neck, not forgetting your ears, nostrils and lips.
• Be sure to check both the top and underneath of your arms. Don’t forget your fingernails.
• As you move down your body don't forget to check places where the sun doesn't shine! Melanoma can be found in places that do not have exposed skin.
• Ask a partner or family member to check your scalp and back.
• The best way to monitor changes on your skin is by taking photographs every few months and comparing them to identify any changes. React quickly if you see something growing and/or changing.
