Distinguishing benign moles from melanoma:
To prevent melanoma, it is important to examine your skin on a regular basis, and become familiar with moles, and other skin conditions, in order to better identify changes. According to recent research, certain moles are at higher risk for changing into malignant melanoma. Moles that are present at birth, and atypical moles, have a greater chance of becoming malignant. Recognizing changes in moles, by following this ABCD Chart, is crucial in detecting malignant melanoma at its earliest stage.
Melanomas vary greatly in appearance. Some melanomas may show all of the ABCD characteristics, while other may only show changes in one or two characteristics. Always consult your physician for a diagnosis.
What is a risk factor?
A risk factor is anything that may increase a person's chance of developing a disease. It may be an activity, such as smoking, diet, family history, or many other things. Different diseases, including cancers, have different risk factors.
Although these factors can increase a person's risk, they do not necessarily cause the disease. Some people with one or more risk factors never develop the disease, while others develop disease and have no known risk factors.
But, knowing your risk factors to any disease can help to guide you into the appropriate actions, including changing behaviors and being clinically monitored for the disease.
What are the risk factors for melanoma?
Skin cancer is more common in fair-skinned people - especially those with blond or red hair, who have light-colored eyes. Skin cancer is rare in children. However, no one is safe from skin cancer.
Prevention of skin cancer:
The American Academy of Dermatology (AAD) has declared war on skin cancer by recommending these three preventive steps:
Wear protective clothing, including a hat with a four-inch brim and sunglasses.
Apply sunscreen all over your body and avoid the midday sun from 10 a.m. to 4 p.m.
Regularly use a broad-spectrum sunscreen with an SPF of 15 or higher, even on cloudy days.
The following steps have been recommended by the AAD and the Skin Cancer Foundation to help reduce the risk of sunburn and skin cancer.
Minimize exposure to the sun at midday - between the hours of 10 a.m. and 4 p.m.
Apply sunscreen, with at least a SPF-15 or higher that protects against both UVA and UVB rays, to all areas of the body that are exposed to the sun.
Reapply sunscreen every two hours, even on cloudy days. Reapply after swimming or perspiring.
Use extra caution near water, snow, and sand - they reflect the damaging rays of the sun, which can increase the chance of sunburn.
Wear clothing that covers the body and shades the face. Hats should provide shade for both the face and back of the neck. Wearing sunglasses will reduce the amount of rays reaching the eye by filtering as much as 80 percent of the rays, and protecting the lids of our eyes as well as the lens.
Avoid exposure to UV radiation from sunlamps or tanning parlors.
Protect children. Keep them from excessive sun exposure when the sun is strongest (between 10 a.m. and 3 p.m.) by having them play in the shade, wear protective clothing, and use sunscreen liberally and frequently - for children 6 months of age and older.
Get vitamin D safely through a healthy diet that may include vitamin supplements. Don't seek the sun.
The American Academy of Pediatrics (AAP) approves of the use of sunscreen on infants younger than 6 months old if adequate clothing and shade are not available. Parents should still try to avoid sun exposure and dress the infant in lightweight clothing that covers most surface areas of skin. However, parents also may apply a minimal amount of sunscreen to the infant's face and back of the hands.
Remember, sand and pavement reflect UV rays even under the umbrella. Snow is also a particularly good reflector of UV rays. Reflective surfaces can reflect up to 85 percent of the damaging sun rays.
How to perform a skin self-examination:
Finding suspicious moles or skin cancer early is the key to treating skin cancer successfully. A skin self-examination is usually the first step in detecting skin cancer. The following suggested method of self-examination comes from the American Cancer Society:
(You will need a full-length mirror, a hand mirror, and a brightly lit room.)
Examine your body front and back in mirror, then the right and left sides, with your arms raised.
Bend your elbows, look carefully at your forearms, the back of your upper arms, and the palms of your hands. Check between your fingers and look at your nail beds.
Look at backs of your legs and feet, spaces between your toes, your toenail beds, and the soles of your feet.
Examine the back of your neck and scalp with a hand mirror.
Check your back, buttocks, and genital area with a hand mirror.
Become familiar with your skin and the pattern of your moles, freckles, and other marks.
Be alert to changes in the number, size, shape, and color of pigmented areas.
Follow the ABCD Chart when examining moles of other pigmented areas and consult your physician promptly if you notice any changes.
