Combined moles are fairly distinctive.
Some of their common features include:
- A large size
- Borders that can be irregular
- Two colours (a brown part and a blue part)
Combined moles can look very similar to melanoma, so it is highly recommended to make sure your doctor checks them regularly for any signs of change.
Some signs that your combined mole may be dangerous include:
- An off-centre blue mole
- Your doctor sees a problem with the lesion during an exam
- You’re over 40, and it’s a newly grown mole
In these cases, your doctor will probably have to perform a biopsy.
