A mole is a growth on the skin that develops when pigment cells (melanocytes) grow in clusters. It is commonly seen in adults in the age group between 10 and 40. These moles are generally found on areas exposed to the sun. Moles usually appear till the age of 40 and in older people, they tend to fade away with age.
There is also a rare possibility of moles turning into melanoma (skin cancer). Though, all moles do not necessarily result in cancer, people who have 50 moles or more have an increased chance of developing melanoma. It is completely curable if detected in the early stages. This is only possible by doing regular mole checks.
