Moles are a type of skin growth made up of pigment cells (melanocytes) that can develop on any area of the body. They often appear in childhood and adolescence, and both sun exposure and genetics play a role in their development. Moles can differ greatly in appearance - they may be small or large, flat or raised, smooth or wrinkled, tan, brown, black, red, pink or blue. The majority of moles are benign. Occasionally, moles may develop into melanoma, the most serious form of skin cancer. If you have new and/or changing moles, or moles that develop symptoms that you are concerned about (such as itching or bleeding) it is important to consult a healthcare professional.
