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.
