Here are seven mole characteristics that might signal serious health issues:

  1. Asymmetry: If one half of the mole does not match the other half in size, shape, or color, it might indicate melanoma, a form of skin cancer.
  2. Border Irregularity: Moles with edges that are blurred, notched, or ragged can be signs of melanoma.
  3. Color Changes: A mole that changes color, has multiple colors, or has uneven shading, especially shades of black, blue, or uneven red, should be evaluated by a dermatologist.
  4. Diameter: Moles larger than a pencil eraser (about 6mm or 1/4 inch) can be a concern, particularly if they’re growing or have recently appeared.
  5. Evolving: Any change in size, shape, color, or elevation of a mole, or new symptoms such as bleeding, itching, or crusting, points to potential skin cancer.
  6. Elevated Moles: A mole that is raised above the skin and has a rough surface could be worrisome, especially if it starts growing quickly.
  7. Painful or Tender: Moles that are painful, tender to touch, or bleed easily could be signs of a serious health condition and require immediate medical attention.

Regular check-ups with a dermatologist are crucial for early detection and treatment of skin cancer if you notice any of these symptoms in your moles.
