1. Asymmetry: The mole is not symmetrical in shape.
2. Border: The border of the mole is irregular, ragged, or blurred.
3. Color: The mole has multiple colors, such as black, brown, tan, or red.
4. Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).
5. Evolution: The mole has changed in size, shape, or color over time.
It is important to note that not all moles that display one or more of these features are cancerous. However, any mole that shows any of these signs or symptoms should be evaluated by a healthcare provider.
Here are some additional factors that may increase the risk of a mole being cancerous:
- Personal or family history of skin cancer
- A large number of moles (more than 50)
- A history of sunburns
- Fair skin that burns easily
- A weakened immune system
If you have any concerns about a mole, it is important to talk to your healthcare provider. They can examine the mole and determine if any further testing or treatment is needed.
