A lesion is asymmetric if half of the mole does not match the other half in size, shape, color, or thickness. In this picture of melanoma, you can see that the left side of the lesion is much thicker than the right side.
Is an asymmetrical mole always cancer?
If you look at a benign, or harmless, mole, it is usually symmetrical. On the other hand, a worrisome mole is asymmetrical, meaning if you cut in half, the two sides do not look the same. Benign moles typically have a regular, round border. Cancerous moles tend to have irregular borders.
What do irregular moles look like?
They are irregularly shaped, with uneven borders that may fade into the skin around the mole. They contain more than one color, including a mixture of brown, black, tan, pink, and white. Their surface may be smooth, rough, scaly, or bumpy.
Can moles be uneven?

In particular with moles. Symmetrical moles on your body are benign (non-cancerous), but if you see one that is asymmetrical – meaning that if you drew a line down the middle of it, the two halves would not match – it’s a warning sign for melanoma.
Can you have stage 4 melanoma and not know it?

How do I know if my mole is bad?
It’s important to get a new or existing mole checked out if it:
- changes shape or looks uneven.
- changes colour, gets darker or has more than 2 colours.
- starts itching, crusting, flaking or bleeding.
- gets larger or more raised from the skin.
What does early stage melanoma look like?
The first sign of melanoma is typically a new spot on the skin, or a change in the size, shape or color of an existing mole. The ABCDE method may help you determine whether an abnormal skin growth may be melanoma: Asymmetry: The mole has an irregular shape. Border: The edge is not smooth, but irregular or notched.
What makes a mole suspicious?
A mole that does not have the same color throughout or that has shades of tan, brown, black, blue, white, or red is suspicious. Normal moles are usually a single shade of color. A mole of many shades or that has lightened or darkened should be checked by a doctor.
Is it normal for a mole to peel off?
A mole is a collection of melanocytes, which are the cells that give the skin its pigment. They can change and evolve over time. Some moles eventually fall off altogether. When healthy moles disappear, the process is typically gradual.
Can a normal mole have two colors?
Most moles have only one or two colours, whereas cancerous moles – melanomas – can be an uneven mixture of light brown, dark brown, black, red or pink.
Can a mole have two colors?
Atypical moles are usually more than two different shades of brown and are not the same color throughout (see drawing). They can sometimes look like a type of skin cancer called melanoma, but they are not melanoma.
What percentage of biopsied moles are cancerous?
Lab testing showed that more than 90 percent of biopsied moles were completely removed by using the single procedure, with 11 (7 percent) diagnosed as melanoma, one of the most aggressive forms of skin cancer.
What do cancerous moles look like?
Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black.
Can a mole change and not be cancer?
Most moles are benign, meaning they are harmless and do not cause cancer. However, sometimes, moles grow and become malignant. This means they are cancerous and must be removed. It is important to keep an eye on all moles.
