When is a mole considered conspicuous?

Indicators are changes in size, shape, colour or border, as well as a mole that looks different from the others. When in doubt, an examination is worthwhile.

How often should I have moles checked?

This depends on skin type, number of moles and medical history. Your doctor will give you an individual recommendation.

Does a changed mole always have to be removed?

No. Many moles are only monitored. Whether removal makes sense is decided after professional assessment.

Changed Mole — Causes, Assessment & the Right Specialty

Moles are usually harmless clusters of pigment-producing cells. However, if a mole changes in size, shape, colour or border, it should be professionally assessed without alarm. Such an examination serves your safety and is a normal, calm part of skin care.

Possible causes

Natural changes

Moles can change slowly over the course of life, for example due to ageing or hormonal changes.

Sun exposure

Intense UV exposure and sunburn affect the skin and the number of moles over the years.

Predisposition

Many moles or fair skin type in the family increase the attention that should be given to skin monitoring.

Irritation

Mechanical friction, for example from clothing, can irritate a mole and temporarily change its appearance.

Typical steps at the doctor's office

1The dermatologist examines the mole, often using a magnifying lamp (dermatoscope), and assesses its shape, colour and border.
2If findings are unclear, monitoring over time or taking a tissue sample for more detailed assessment may be suggested.
3Further steps depend on the results and range from regular observation to removal of the mole.

What you can do yourself

Examine your own skin from time to time and watch for changes in size, shape or colour.
For areas that are difficult to see, such as your back, use a mirror or ask another person for help.
Maintain consistent sun protection with clothing, shade and sunscreen, and avoid sunburn.
Photograph conspicuous areas with your mobile phone to better detect changes over time.

When a doctor's visit makes sense

A mole that changes in size, shape or colour, appears newly or feels different should be assessed by a dermatologist. Such an examination is not a diagnosis, but rather a sensible precautionary measure that provides clarity quickly and easily.
