Mole mapping

What is mole mapping?

Mole mapping uses computerised digital dermoscopy technology to monitor your skin and magnify moles on your body. During this investigation, digital images of moles can be analysed and stored for making comparisons at future visits. These comparisons will help us identify any changes to existing moles or development of new moles. We will also be able to determine if existing moles have become cancerous by tracking changes in their shape, size or colour. This makes it possible to identify cancerous moles, also known as melanomas, that are not obvious to the naked eye at early stages. Mole mapping can help you avoid the unnecessary surgical removal of normal moles as well, which can reduce your chances of scarring too.

How does mole mapping work?

Mole mapping involves taking high-quality digital images that include close-ups of individual moles that might be a cause for concern. Once Dr van Heerden has completed a scan and evaluated these dermoscopic images, he will confirm your diagnosis and recommend any necessary treatment. Treatment is usually needed if moles or lesions indicate the presence of melanoma.

If there are moles that are of concern, Dr van Heerden may recommend a follow-up mole mapping procedure after three to six months to check if they have changed in shape or size. In other cases, a routine follow-up is recommended once every one to two years to make sure your moles have not changed.

Who should undergo mole mapping?

Mole mapping is recommended for anyone who has a lot of moles on their skin, particularly if they are large, or unusual in shape and colour. Individuals with a family or personal history of melanoma, or with very fair skin or who have had severe sunburn in the past, should consider regular mole mapping to track any changes in their moles. If you have noticed a mole that has changed in appearance, it is advisable to consult with Dr van Heerden.

Mole mapping is one of the most effective methods of diagnosing melanoma, especially at an early stage. Early detection of melanoma is essential to reduce the spread of melanoma cancer.
