Normal moles are symmetrical in shape, meaning if you were to draw a line down the middle, both halves would look the same. Asymmetrical moles are abnormal and should be checked by a doctor. The image on the left is an example of a symmetrical, benign mole.
Are all asymmetrical moles skin cancer?
Most melanomas are asymmetrical. If you draw a line through the middle of the lesion, the two halves don’t match, so it looks different from a round to oval and symmetrical common mole.
What does an asymmetrical mole look like?

Are irregular moles always cancerous?

In Stage I melanoma, the cancer cells are in both the first and second layers of the skin—the epidermis and the dermis. A melanoma tumor is considered Stage I if it is up to 2 mm thick, and it may or may not have ulceration. There is no evidence the cancer has spread to lymph nodes or distant sites (metastasis).
