Yes, beauty marks, which are also known as moles or nevi, are generally normal. Most people have moles, and the vast majority are harmless. They are not contagious and typically do not cause pain, itching, or bleeding. A mole's lifespan can be as long as 50 years.
Understanding Beauty Marks and Moles
A beauty mark is simply a small, dark spot on the skin, usually round or oval, that's either flat or slightly raised. These spots are formed by clusters of pigment cells (melanocytes). The commonality of moles varies; people with fair skin may have between 10 and 40, while others may have fewer or more.
- Normal Moles: These are usually symmetrical, small (<6mm), have smooth borders, and exhibit a uniform color (usually brown or tan).
- Variations in Appearance: Moles can vary in color, ranging from light brown to dark brown or even black. Some might be red, especially cherry angiomas, which are a different type of skin growth.
- Number of Moles: Having many moles (50 or more) increases the risk of developing melanoma, a dangerous form of skin cancer, but most moles remain benign.
While most moles are benign, it's crucial to monitor them for changes. Any changes in size, shape, color, or the appearance of new symptoms (itching, bleeding) warrant a visit to a dermatologist.
When to Worry
Although most moles are harmless, a change in a mole's appearance can indicate a potential problem. The ABCDEs of melanoma detection can help you identify potentially cancerous moles:
- Asymmetry: One half doesn't match the other.
- Border: Irregular, ragged, or blurred edges.
- Color: Uneven color, with shades of brown, black, tan, white, or red.
- Diameter: Larger than 6 millimeters (about the size of a pencil eraser).
- Evolving: Changing in size, shape, or color.
Early detection is key in treating melanoma. Regularly checking your moles, or having someone else do it, is vital for early detection.
