Which statement is true about moles?

Explanation:
A mole is a spot of extra melanin, the pigment that gives skin its color. It forms where pigment-producing cells called melanocytes cluster in one area, producing more pigment than surrounding skin. Because of that increased pigment, the mole appears darker or differently colored than the surrounding skin. Moles are not caused by bacteria or viruses, and they’re not contagious. They can be present at birth or develop later in life, and while most are harmless, any mole that changes in size, shape, color, or starts itching or bleeding should be evaluated by a clinician.
