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.
For unclear reasons, melanomas from existing moles generally have a better prognosis than those that appear as new spots, the research adds.
Yet, despite these findings, experts still recommend people check their moles regularly for any changes.

Eating at strange times makes skin more vulnerable to harmful UV rays, research suggested last month.
Feeding mice on abnormal schedules causes their skin to become more damaged when exposed to sunlight, a study found.
This is due to them producing less of a specific enzyme that repairs UV damage, the research adds.
Study author Dr Joseph Takahashi from the University of Texas, Dallas, said: 'It is likely that if you have a normal eating schedule, then you will be better protected from UV during the daytime.'
UV rays are in sunlight and are responsible for nearly all cases of skin cancer worldwide.
Some 71% of cases start as spots
Researchers from the University of Modena and Reggio Emilia in Italy analysed 38 melanoma studies.
Results reveal that less than a third of cases develop from existing moles.
Some 71 per cent appear as new spots on the skin.
