Skin can be soft, smooth and pleasing to the eye, but it has important protective and immune functions. Its outer layer of the epidermis forms an impenetrable barrier to water, and its immune specific cells protect us from pathogens. It is a strong outer defense for our body, but due to sun exposure and time, the skin becomes less resilient. We develop pigmented lesions, fine lines, wrinkles and sagging. Also, sun exposure increases our odds of developing skin cancer. Therefore, it is important to have a regular skin exam as we age.
Sunlight is important for production of vitamin D, which is necessary for bone health and our immune system, but over exposure causes cumulative damage to our skin, increasing the likelihood of skin cancer. When evaluating moles and pigmented skin lesions, we use the ABCDE method:
A – Asymmetry
B – Border uneven or scalloped
C – Color uneven, changing in color
D – Diameter greater than 6mm
E – Evolving, changing its border, color or size
You should see your healthcare provider if you notice a change in color, size or shape of a mole or if you have developed a new mole in adulthood. Any mole that itches, bleeds or is painful should be checked, and anyone who has a family history of skin cancer should have periodic skin exams.
If a mole is suspicious, it can be biopsied. A biopsy uses either a razor, a punch or scalpel to obtain a portion of the mole for microscopic examination. Fortunately, most skin cancers can be treated by simple excision.
If you have any suspicious mole or need a skin exam, please contact your primary care provider or call Dr. Ripley at 928-668-1833 for a skin cancer screening.
