There is a simple approach to perform a self-exam of your moles. Remember that the most of the moles are benign moles. The only method to detect the melanoma early is to check regularly your moles.
Melanoma is the most deadly skin cancer. An estimated 46,000 Americans will develop melanoma every year, and 7,700 Americans will die from melanoma every year. And because of that it is important to know how to recognize the early warning signs of melanoma.
The rule is simple and it is called ABCD rule
A for Asymmetry: One half of the mole does not match the other half in size, shape, color or thickness
B for Borders: The edges o of the mole are ragged, scalloped, blurred, or poorly defined.
C for color: The color of the mole is not one and the same throughout or it has shaded of tan, brown, black, red, white or blue.
D for Diameter: The moles greater than 6mm are rather possible to be cancerous.
Be careful and look for any changes in the mole. For the best use some check moles tool.
