Important Steps to Prevent Moles

Not all moles are cancerous, and most melanomas form independently of moles. However, it is important to recognize possibly dangerous skin growths and moles to detect skin cancer at early stages when it is still very treatable.


This is a tool used to examine moles and other skin growths. ABCDE stands for Asymmetrical, Border irregularities, Color, Diameter and Evolving. Melanomas are usually asymmetrical, meaning that each half of the growth or mole appears differently. The border of a melanoma is usually with notches and they are usually have multiple colors. The diameter of a melanoma is usually greater than 6mm as well. Moles that evolve, or change in shape, color, etc., should be checked by a skincare professional. Remember, however, that not all melanomas follow these rules. Some melanomas may be uniform in color, symmetrical, smaller than 6mm in diameter and have a normal border. It is important to have any new mole or growth checked, as well as changes to existing moles or growths.

Avoid the Sun

Some researchers believe that the sun plays a role in the development of moles. Research is still being conducted to determine the cause of moles, but many dermatologists recommend avoiding excessive sunlight to prevent other symptoms of sun damage like freckling, wrinkles, etc. Sun exposure may also lead to skin cancer, so wearing sunscreen and the proper clothing to prevent damaging sun exposure is important. Talk to a skincare professional for more information regarding the relationship between moles and skin cancer, and how avoiding sun exposure may help to reduce your risk of skin cancer.
