  • An uneven or unusual shape
  • More than one colour, or colour that starts to change
  • Sudden growth or noticeable changes in appearance
  • Itching, bleeding, scabbing, or becoming painful
  • A size bigger than 6 mm, or a mole that suddenly starts to swell
• What should you do:
  • If you see warning signs in your mole, book a consultation with your dermatologist as soon as possible. Acting early is one of the most effective ways to protect yourself from a potential skin cancer.

 

Introduction

Having moles is normal and most of them do not cause any harm. Not until a familiar mole starts changing. Sometimes these changes are harmless and just part of ageing skin, but some changes can also be a warning sign of something more serious. It is worth knowing that melanoma is a fast growing type of skin cancer, and is increasing in the UK, but with early detection, treatment will be more successful.

Let us take a deeper look at the top five signs that should never be ignored.

 

Asymmetrical Mole Shape

Normal moles are round or oval, with neat outlines. If a mole starts looking uneven, it could be a warning sign.

A good way to remember this is that the A in the ABCDE rule stands for Asymmetry.

You might notice:

• One side is more raised than the other
• The edges looked jagged or rough
• The shape looks stretched or uneven

These changes do not need to hurt to be serious, because melanoma can grow quietly without causing pain.

 

Uneven or Changing Colour

Most moles that are healthy are just one colour. Colours might be tan, brown, or pink. In the ABCDE rule, the C stands for Colour. Watch for:

• Dark spots appearing inside the mole
• Different colours mixed together
• Patchy or faded area
• The mole getting darker

Even small colour changes matter, so it is safer to get them checked by a dermatologist. And if the mole turns out to be harmless, you can still choose to remove it for appearance.

 

Quick Changes in Mole Appearance

If the mole starts to grow or has changes in its looks, it should be checked by a doctor right away. In the ABCDE rule, D stands for Diameter. Look out for:

• The mole is growing bigger within weeks or months
• It looks more raised or thicker than before
• The surface becomes rough, dry, or bumpy
• Edges starts to look different or uneven

A small change is important to note. Even a growth of 1 to 2 mm matters too.

 

Bleeding, Itching, or Scabbing

When a mole suddenly starts itching, hurting, bleeding, or forming scabs for no reason, get it checked right away.

Pat attention if a mole begins to:

• Persistent itching
• Feel tender and sore
• Bleed without being scratched or bumped
• Form scab that keep coming back
• Look crusty without healing

In the ABCDE guide, E stands for EVolving, which means “changing over time”. Sometimes melanoma is harmless, but these symptoms can also point to melanoma growing under your skin.

A bleeding mole is especially worrying. SKin cancers can weaken the surface, making moles break open easily.

 

Diameter Over 6 mm or Swelling

When a mole grows larger than 6 mm, it may need a closer look. Many big moles are harmless, but skin cancers are more likely to grow past this size.

Why does size matter?

Larger moles allow abnormal cells more room to grow. Melanoma can also spread deeper under the skin, where changes are not visible. Removing it early makes treatment simpler and more effective.

Watch out for any of the following:

• The skin around the mole become swollen
• A mole that was flat suddenly become raised
• Tightness, soreness, or discomfort around a bigger mole.

 

How to Check Moles at Home: The ABCDE Method

Checking your moles at home does not need to be complicated, dermatologists around the world use a simple guide called the ABCDE method to spot warning signs early.

Here is what to look for:

ABCDE Rule	What It Means
A: Does your mole look asymmetrical?	One half of the mole does not match the other.
B: Do the borders look irregular?	The edges look uneven or rough.
C: Is the colour unusual?	There are different colours in the same mole, or colour starts to change.
D: Is the diameter getting bigger?	It is bigger than 6 mm or it starts growing.
E: Is it evolving or changing?	Anything new or changing, like size, colour, texture.

Check your skin in a good lighting condition. Taking a photo every few months can help you notice any changes.

 

When to See a Doctor?

Many people are not sure whether to see a GP first or go straight to a skin specialist.

Book a dermatology consultation if:

• The mole shows one or mole ABCDE signs
• It bleeds, scabs, or grows suddenly.
• There are changes in texture and colour
• A new mole appears after age 40

See your GP first if:

• The mole looks unusual but has not changed
• You are not sure if it is evolving
• You want a medical referral before treatment.

A GP can give you advice, but a dermatologist is the expert who can perform mole mapping, professional assessment and biopsy if you need any.

 

What If a Mole Raises Concern

You will be recommended for a biopsy if your doctor suspects your mole is unsafe. This is a safe procedure where the part of your mole is removed and checked under a microscope.

If the results show the mole is benign, you would not need any more treatment, except if you want to remove your mole due to appearance. But, if there are abnormal or cancerous cells found, your doctor will explain and proceed to the next steps of treatment.

 

Why Spotting Changes Early Is Important

Melanoma sometimes can become aggressive and spread deeper into the skin and spread into the body. But when detected early, it is one of the most treatable cancers.

Early detection means:

• Reduced scarring from removal
• Less invasive treatment
• Minimal disruption to daily life
• Higher survival rates

By acting at the first sign of change, you protect not only your skin but also your overall health. A small decision today such as booking a dermatology consultation can prevent a major medical issue tomorrow.
