Most of the time, moles are harmless. However, there are times when they need to be removed, to avoid certain complications such as cancer. In this guide, we explain in detail how and when to consult us about a mole!
What is a mole?
A mole is an outgrowth of the skin. Melanocytes (the cells responsible for pigmentation) accumulate under the skin and, voila, you have a mole!
Most moles form during childhood, often as a result of sun exposure. The hereditary factor also has to be taken into account: if one of your parents has a lot of them, it’s very likely that you will too.
It is still possible to be born with moles. These are called congenital melanocytic nevi.
Benign moles
Most moles are benign: in other words, they are not dangerous. However, they should be monitored because they can develop into melanoma (skin cancer). They are characterised by
- They are symmetrical in shape
- They have a regular border
- The colour is uniform
Benign moles may change over time. For example, a child who grows up will see the size of his mole grow with him. They may also change colour (generally darkening or lightening in a harmonious way).
Dangerous moles
A mole can become dangerous if you notice these different characteristics:
- It has changed shape
- It has grown very quickly
- Its colour changes unevenly
- It bleeds or a crust forms on its surface
New moles can also appear spontaneously. They can be dangerous if:
- They are not symmetrical
- They are irregular in shape
- They are larger than 6mm
If you notice one or more of these symptoms, you should make an appointment to see a dermatologist as soon as possible to rule out any risk of melanoma.
People at risk
Some people are more likely to develop dangerous moles:
- People who work a lot outdoors and in the sun
- Those with more than 50 moles
- People with very fair skin who have often been sunburnt
- People with a family history of melanoma
How do I make an appointment with a dermatologist?
There are several ways of seeing a dermatologist about your moles for a skin examination. You can go through your GP, who will be able to request a referral for a consultation with a dermatologist. You can also go via the OneDoc platform. You’ll be able to make an appointment easily and in just a few clicks.
As far as insurance is concerned, we recommend that you always find out about the LAMal reimbursement arrangements beforehand. It is sometimes necessary to have a prescription from the treating doctor.
