Skin Cancer: ABCDE, the Simple and Effective Method for Identifying a High-Risk Mole

This effective method can identify a suspicious mole that could be a sign of skin cancer.

Does it look like one of your moles has evolved and changed shape or colour? Don't panic. The ABCDE method is the most effective way to identify a suspicious mole.

The ABCDE method to detect dangerous moles

Detecting a mole that can develop into cancer can be spotted with the naked eye. Before going to the dermatologist, you can yourself identify suspicious moles yourself using the ABCDE method, which is easy to remember:

  • A for Asymmetrical: A mole is suspicious if it is asymmetrical.
  • B for Borders: Irregular borders on the mole can also be a sign.
  • C for Colour: A mole can go from light brown to dark black through depigmented white areas to red or blue areas of the skin.
  • D for Diameter: A mole is suspicious if it is more than 0.2 inches in diameter.
  • E is for Evolution: Check to see if the mole enlarges or if the colour and thickness change.

An appointment with a dermatologist is essential

80,000 cases of skin cancer are diagnosed each year. This is why it is essential to go to the dermatologist every year to have a check-up and to verify the evolution of moles. You can also ask your general practitioner to carry out an initial check-up.

If it turns out that one or more moles are suspicious, the dermatologist will suggest a second appointment to remove them. This is a small operation performed under local anaesthesia with a scalpel. The mole is removed and the wound is closed with stitches. Even if the at-risk mole is removed, you will still need to have it checked at your annual appointment.
