Deadly skin cancer starts as new spots on the skin, not moles, in more than two-thirds of cases, new research reveals.
In 71 per cent of incidences, melanoma, the most life-threatening form of skin cancer, develops as marks on the skin, rather than arising from existing moles, a study found.

Yet, despite these findings, experts still recommend people check their moles regularly for any changes.
