A mole is a common skin growth that can appear anywhere on the body. While most moles are benign, meaning they are not cancerous, it is important to have them examined to see if they exhibit certain characteristics.   Here are some signs that a mole should be examined:   Change in size: If a mole suddenly grows in size or becomes larger then a pencil eraser, it should be examined.   Change in shape: If a mole becomes irregular in shape or develops an asymmetrical appearance, it should be examined.   Change in color: If a mole changes color, becomes darker or lighter, or develops multiple colors, it should be examined.   Irregular border: If a mole has an irregular or blurred border, it should be examined.   Itching, bleeding, or crusting: If a mole becomes itchy, bleeds, or develops a crust, it should be examined.   Family history: If you have a history in the family of skin cancer, you should have your moles examined regularly.   Keep in mind that not all moles that exhibit these characteristics are cancerous, but it is important to have them examined to rule out any potential health issues.   Dr. Rosenberg can perform a simple biopsy to determine if the mole is cancerous and recommend appropriate treatment if necessary. Regular skin checks can help detect potential issues early and promote better overall health.
