How to recognise if a mole is normal?
Most people have moles and usually, they are completely harmless. Moles develop when pigment-producing cells called melanocytes grow in clusters within the skin. Some are present from birth, while others appear throughout childhood and early adulthood. Genetics, skin type and sun exposure can all influence how many moles a person develops over time.
What does a normal mole look like?
A typical benign mole is usually round or oval and has a clear, well-defined border. The colour is generally even throughout the mole, although shades can vary from light brown to very dark brown. Some moles are raised while others are flat. Importantly, most harmless moles remain relatively stable and don’t change in size, shape or colour significantly over time.
Why change matters
One of the most important things to remember is that skin cancer is often only identified because a mole changes. A mole that becomes larger, develops an irregular shape, changes colour or starts behaving differently should be assessed by a dermatologist or GP.
What about texture?
A mole that itches, bleeds, crusts or becomes persistently sore should always be checked. These symptoms don’t automatically mean skin cancer is present, but they should never be dismissed. New symptoms deserve attention, particularly if they persist for several weeks.
Are regular skin checks really necessary?
You don’t need to examine every mole every day, but becoming familiar with your skin is extremely helpful. Regular self-checks make it easier to notice new moles or changes in existing ones. Many people find it useful to take photographs to monitor their moles over time, especially in areas that are difficult to see easily.
Final thoughts
Most moles are harmless and remain unchanged for many years. The key is to become familiar with your own skin and pay attention to anything new, changing or unusual. If a mole concerns you for any reason, seeking professional dermatological advice can provide reassurance and ensure that any potential problems are identified as early as possible.
