I'm an expert in dermatology with over a decade of experience in diagnosing and treating skin conditions. When it comes to moles, it's important to understand that not all black moles are cancerous. Moles, also known as nevi, are common skin growths that can be flat or raised and can vary in color from skin-toned to brown, black, or even blue. Most moles are harmless, but some can develop into a type of skin cancer called melanoma.
However, the presence of a black mole is not a definitive sign of cancer. It's the change in a mole's appearance or the development of certain characteristics that can be concerning. Dermatologists use the ABCDE rule to help identify potentially cancerous moles:
1. Asymmetry: Normal moles are usually symmetrical, while melanomas may be asymmetrical.
2. Border: The borders of melanomas tend to be irregular, notched, or blurred.
3. Color: Moles with multiple colors or uneven color distribution can be a sign of melanoma.
4. Diameter: Melanomas are usually larger than typical moles, often greater than 6 millimeters in diameter.
5. Evolution: Any change in size, shape, color, elevation, or another trait, or the appearance of a new symptom (such as bleeding, itching, or crusting) can be a sign of melanoma.
It's crucial to have any moles that exhibit these characteristics or that change over time evaluated by a dermatologist. Regular self-examinations and annual skin checks by a healthcare professional are recommended for early detection.

A normal mole, like the one pictured here, is usually an evenly colored brown, tan, or black spot on the skin. It can be either flat or raised, round or oval. Melanoma is a cancer that begins in the cells that give skin its color. Normal moles also develop from these skin cells.
