Skin cancer can be detected at an earlier stage when you are aware of the ABCDE rule. Skin cancer is the most common and preventable type of cancer in the United States. But remember that melanoma – third in terms of prevalence – is the deadliest skin cancer.
Dermatologists developed the ABCDE rule to easily identify any spots on the skin and suspicious moles. Although relatively helpful, always note that there are still exceptions from the rule in certain cases.
The ABCDE Rule:
A – Asymmetry
Try to draw a line at the center of your mole, both sides should be equally same. Asymmetrical or those with irregular shapes are considered at risk of being cancerous. Remember that a non-cancerous mole should always have a symmetrical appearance.
B – Border
Blurred, notched, or ragged borders of spots should always be checked. The pigment around the border is also important to note.
C – Color
Unusual colors and shades are being checked in melanoma spots. The unusual colors are pink, red, brown, gray, white, or black. Monitor the color changes as it could be a sign of concern.
D – Diameter
The diameter of the melanoma spot that is larger than a pencil eraser. But, according to Dr. Clifford Perlis, a dermatologist from the Fox Chase Cancer Center in Philadelphia, not all melanoma spots are larger than a pencil eraser. It's still better to consult a doctor.
E – Evolution
Studies revealed that not all melanomas came from existing moles. At the age of 30, new moles will stop to grow. You should talk to a doctor if there are new growths beyond this age. Dr. Bruce Robinson, a dermatologist in New York City, said that new moles are itchy, will give you a burning sensation, and the color becomes different as it grows.
