It is difficult to tell if a mole is becoming a melanoma without expert advice. Most melanomas start with a change in the appearance of normal skin. Only one third develop from existing moles. However, most moles are smooth, regularly shaped and of a single colour. Changes in the size, shape or colour and the presence of sensations such as itching or bleeding are signs that a mole may be turning into a melanoma.

There are some factors that increase a person’s risk of developing a melanoma. These include being very fair skinned, easily burning in the sun, being sunburnt, (particularly as a child), exposure to artificial sources of Ultra violet light (sun beds etc) and having two people in the family previously diagnosed with melanoma.

You might find it helpful to discuss your concerns with your GP and ask that he/she examine your skin. If your doctor felt there was any cause for concern he/she might suggest that you see a skin specialist (a dermatologist) so they can check all your moles and advise you on what to look out for.
