A mole (a nevus) is a small or dark spot on your skin that forms from pigment cells, which give your skin its colour. Some moles are present at birth, while others appear later in life, often because of sun exposure or hormone changes. 

Most moles are harmless and stay the same for many years, but it's important to watch them because changes can sometimes mean a skin problem.

Moles can look different, but safe moles are usually round, evenly coloured, small, and do not change over time. Adults usually have 10–40 moles, and they can change with age, hormones, or sun exposure. Most moles are harmless, but regular checks are important.

You should see a doctor if a mole grows quickly, changes colour or shape, has uneven edges, or starts to itch, bleed, or hurt.

Types of Moles:

Not all moles and skin spots are the same. While many are harmless, some can signal skin problems, including skin cancer. Knowing your moles and checking them regularly is key to staying safe.

• Common: Small, smooth, dome-shaped, usually harmless.
• Atypical (Dysplastic): Irregular edges, mixed colours, may be larger; slightly higher risk of skin cancer.
• Congenital: Present at birth; monitor, as they can carry some risk.
• Acquired: Develops during childhood or adulthood, usually harmless.
• Junctional, Intradermal, Compound, and Halo Nevi: Variations based on cell location and appearance; most are harmless but should be monitored.
  

How to know if a mole is safe:

• Have neat edges
• Are dome-shaped or smooth
• Are about 6mm or smaller
• Keep the same shape, size, and colour over time

• Irregular or asymmetrical shape
• Itchiness, bleeding, or crusting
