What is a Mole?

Moles are small, dark spots on the skin caused by a cluster of pigment-producing cells. They are usually brown or black in color and can range from a few millimeters in diameter to the size of a pea. They can also be raised above the skin and may be irregular in form. Moles are found in people of all skin colors and ethnic backgrounds and are typically present from birth, although some may not appear until later in life.

What Causes Moles?

Moles are caused by the overproduction of melanin, the pigment that gives skin its color. Sun exposure is the most common cause of moles, and your risk increases with age. Genetics also plays a role, and some people are born with moles. Additionally, certain medications and hormones can produce moles or cause existing moles to darken.

Are Moles Dangerous?

Most moles are harmless; however, it’s important to monitor them for changes. Be aware of any changes in size, shape, color, or texture. These could indicate the early stages of skin cancer. If you notice any of these changes, or if a mole becomes painful or itchy, see a dermatologist. It’s also a good idea to perform monthly skin checks and seek a professional opinion if you have a lot of moles or any unusual-looking moles.
