Congenital moles
- These are moles that are present at birth.
- Such moles vary in sizes.
- They are usually present on the trunk.
- These congenital moles may develop into cancers (melanoma). Therefore, they should be removed whenever possible. The larger the congenital mole, the higher the risk of cancer developing later on.
- Congenital naevi may be associated with other malformations.
Actinic keratosis
- These lesions are seen on the sun-exposed skin especially on the face, upper chest, back and forearms.
- They appear as scaly reddish or brown patches on the skin.
- Numerous lesions may occur at the same time.
- If left untreated, they can go on to develop into skin cancers.

Treatment of Pre-malignant growths
- These can easily be destroyed using liquid nitrogen (like dry-ice) or anti-cancer ointments or electrosurgery or excision surgery or laser surgery.
- If you have a skin tumour, it is advisable to check it out with your doctor. He can then advise you on the diagnosis and action to be taken.
