A mole that has recently changed in appearance -- such as becoming elevated, in your case -- definitely needs to be evaluated by a dermatologist. The ABCDE rule of skin cancer states the characteristics of abnormal moles:
- Asymmetry: Normal moles or freckles are completely symmetrical. If you were to draw a line through a normal spot, you would have two symmetrical halves. In cases of skin cancer, spots will not look the same on both sides.
- Border: The borders or edges of an irregular mole are uneven, jagged or blurry.
- Color: Normal moles are uniform in color. Moles are considered to be abnormal when they are more than one color or shade. This can include lightening or darkening of the mole.
- Diameter: If a mole is larger than a pencil eraser (about 1/4 inch, or 6mm), it is considered to be abnormal. This includes moles that do not have any other abnormalities (color, border, asymmetry).
- Evolution: Evolution refers to any changes in the symmetry, borders, colors, and diameter of an existing mole.
Abnormal Moles Are Not Always CancerousYou should know that not all abnormal moles are cancerous. If you do have an abnormal mole, it is very important to have it checked out by a dermatologist. An untrained eye cannot determine if a mole is likely to be cancerous or not. It is important for you to check your skin monthly and have a yearly clinical skin exam by a doctor.
During a clinical skin exam, a doctor visually examines the skin to look for any new developments or changes to existing moles or spots. Remember, if you find anything abnormal, report it to your doctor as soon as possible. Do not wait for your yearly exam.
