The majority of nevus are non cancerous and not serious.
However if the nevus changes in shape, color, size or border you should see your doctor or a dermatologist.
The signs that the nevus could be cancerous include.
Redness or a new swelling beyond the border of the mole.
A change in sensation, such as itchiness, tenderness, or pain.
Change in the surface of a mole like scaliness, oozing, bleeding, or the appearance of a lump or bump.
Congenital moles will need to be monitored for skin cancer.
Some may also be removed for cosmetic or functional reasons, especially when the placement of a mole causes emotional distress for a child.
Surgical excision remains the standard treatment for removing a congenital nevus.
