Discover Mole-Mapping

Mole-mapping is a medical record which records images and the location of lesions and/or moles or dark spots on the body.

It is useful because it not only detects an immediate problem but your moles are also scanned digitally and then stored so that when you return for a follow up later, you can detect any changes in the composition and density of the mole – which is one of the key signs of skin cancer.

Who Should Come For This Procedure?

Adults over the age of 18 years. Practically speaking, the following people should consider mole mapping:

  • Patients with many moles
  • Patients with atypical moles
  • People with fair skin and a history of excessive sun exposure
  • Patients with a personal history of melanoma
  • Patients with a family history (1st-degree relatives) of melanoma
  • Anyone who is concerned about his/her moles.

What Can I Expect?

Mole mapping takes place in 2 stages:

  • Full body photography is done to record where the moles are located on the patient’s body.
  • Each mole is photographed with a specialised dermoscopic camera. The picture is stored in the computer’s database and the position of the mole is captured on the patient’s body.
  • The image of the mole is then analysed, either by the dermatologist or by the computer itself.
  • On the patient’s future return visit, each image can be compared with its earlier picture.

How Often Should I Be Mole-Mapped?

  • This would depend on the patient’s risk analysis.
  • Most people require an annual visit. However, following the diagnosis of melanoma, patients are seen every 3-6 months, for the following 2 years. This is then followed by annual visits.
