What Causes Moles?

So what causes moles? Well, there are a couple of answers to this question.

Congenital nevi are moles that appear at birth as a result from a proliferation of benign melanocytes in the dermis, epidermis, or both and occur in about 1 in 100 people. These moles may be more likely to develop into melanoma (cancer) than are moles that appear after birth. A mole or freckle should be checked if it has a diameter of more than 7 mm.

Moles can also be caused by too much sun exposure and tend to appear in the areas where the skin catches the most sunlight. Moles become darker when exposed to the sun. If you have moles and you are constantly going outdoors and exposed to sunlight you may be at risk. Make sure to apply the proper sunscreen.

Moles may also be hereditary. If you do have moles, make sure that your family doesn't have a history of skin cancer. If skin cancer runs in the family, make sure to see your dermatologist.

The good news is that most moles are benign. It's only certain types of moles that come with an increased risk of melanoma - or skin cancer. These moles are often hereditary and are generally irregular in shape and color.

It's a good idea to keep a close watch on your moles. If a mole begins to change in shape, size or color or becomes irritated, you should see a dermatologist. But remember, most moles aren't dangerous. Just think of them as beauty marks.
