Change in the shape of a mole

A change in the shape of a mole can be a sign of skin cancer, such as melanoma. Moles may become larger, more irregularly shaped, and may have different colors or an uneven border. It may also have a mixture of colors, such as red, white, and blue. As the mole changes, it may become raised or have an indentation in the center. It is important to monitor any changes in the size, shape, or color of a mole, as this can be an early sign of skin cancer.
