Moles, those small, often inconspicuous spots that dot our skin, are more than just cosmetic quirks; they hold clues to our body's inner workings. Let’s unravel the mysteries surrounding moles, exploring their origins, when to pay attention and the considerations surrounding their removal.
Moles, scientifically known as naevi, emerge from a complex interplay of factors:

![]() Moles often emerge during childhood and adolescence, though they can appear at any stage of life. Their size, colour and distribution may evolve over time, reflecting the dynamic nature of our skin. |

![]() Much like inherited traits, the propensity for developing moles can run in families. Genetic factors significantly influence their appearance and distribution across the skin. |
![]() |
![]() The sun's UV rays are a potent catalyst for mole formation. Prolonged exposure to UV radiation can stimulate the growth of moles and increase the risk of skin cancer, including melanoma. |

![]() Hormonal changes, such as those occurring during puberty, pregnancy, or hormone therapy, can trigger the development of new moles or alterations in existing ones. Fluctuations in hormone levels exert a profound influence on skin health and physiology. |
While most moles are harmless, changes in size, shape, colour or texture may indicate a potential problem. It's essential to be vigilant and monitor your moles regularly. Here are some signs that a mole may warrant further attention:1,2
The decision to remove a mole depends on various factors, including its size, location and whether it shows signs of cancerous changes. In many cases, moles are removed for cosmetic reasons or because they are in areas prone to irritation, such as the armpits or groin.
However, if a mole exhibits any concerning features, a dermatologist may recommend a biopsy to determine whether it is cancerous or precancerous. If cancerous cells are present, the mole will need to be surgically removed to prevent further spread.
It's important to note that attempting to remove a mole at home can lead to complications, including infection and scarring. Dermatologists have the expertise and tools necessary to safely remove moles and minimize the risk of complications.
While generally safe and effective, it's essential to be aware of the potential risks and complications associated with this removal process. Understanding these risks can help you make an informed decision and mitigate any adverse outcomes. Below are some key risks to consider:

![]() One of the most common risks associated with mole removal is scarring. Depending on the size, depth and location of the mole, the procedure may leave behind a visible scar. While dermatologists employ various techniques to minimize scarring, such as suturing or laser therapy, some degree of scarring is unavoidable in certain cases. |

![]() Like any surgical procedure, mole removal carries a risk of infection. Despite strict sterile techniques, bacteria may enter the wound site, leading to redness, swelling, pain, and discharge. Prompt medical attention and proper wound care can help prevent and treat infections effectively. |

![]() Mole removal may cause bleeding, particularly if the mole is large or located in a highly vascularized area. While minor bleeding is normal and typically resolves on its own, excessive bleeding may require medical intervention to control. |

![]() In rare cases, mole removal may result in nerve damage, leading to temporary or permanent numbness or altered sensation in the surrounding area. This risk is more common with larger or deeper moles or when the procedure involves cutting or excising nerve-rich tissue. |

![]() Despite complete removal, moles may occasionally recur in the same location. This recurrence may be due to residual mole cells left behind during the initial procedure or the development of new moles in the vicinity. |
In conclusion, while moles are generally harmless, changes in their appearance should not be ignored. Regular self-examinations and annual skin checks by a dermatologist can help detect skin cancer early when it is most treatable. If you have concerns about a mole, consult a healthcare professional promptly for evaluation and appropriate management.
