The reason behind why we have moles in our body is due to melanocytes, common skin growths formed by clusters of pigment-producing cells in the body.
Mostly found in sun-exposed areas, they are harmless and don't require treatment, but some moles can develop into melanoma, a skin cancer.
Moles are thought to be impacted by genes and sun exposure, with persons with fair skin and light hair being more likely to get moles.
Most individuals usually have 10-40 moles on their body in various areas like the scalp, armpits, beneath the nails, between fingers and toes.
Over time moles can change or disappear but hormonal changes during puberty and pregnancy can cause darker, larger moles.
