Frequently asked questions
When is a mole a cause for concern?
Watch for changes in size, shape, colour or border, and for bleeding or itching. Any such change should be checked by a doctor.
Is it safe to remove a mole for cosmetic reasons?
Yes, moles can be removed by a doctor. It is best not to attempt removal yourself, as this risks infection and misses the chance to test the mole.
