Dermatology (Skin conditions)

Mole

Moles or naevi are very common. Everybody has at least one or two. On average an adult in their late twenties will have between twenty and thirty naevi or moles. 

A mole will change in appearance during a lifetime. Initially it will appear as a flat brown mark. Later it becomes a raised brown mark and later still a raised pink mark often with hairs growing through. These are all normal changes that can be expected in a mole. 

Very rarely and exceptionally moles change into malignant melanomas. The risk of this happening is very difficult to assess but probably less than 1 in 200,000 i.e. not so great there is any need to cut out normal moles in otherwise normal people. People who are slightly more at risk from developing melanoma are those who have had melanoma before, those with a family history of melanoma and those with multiple very odd looking moles. 

Moles on the scrotum and soles of the feet, palms or hands are no more dangerous than moles anywhere else. 

If your mole is considered to be benign you will be reassured and discharged and no treatment will be offered. 

Occasionally a healthy mole will develop a halo or rim of white skin around it. This usually means that the mole is going to gradually disappear spontaneously. It is not a sinister sign. The white skin will be vulnerable to sunburn but will slowly re-pigment.
