Moles, a sign of "slower ageing"

The number of moles may offer an indication of how quickly the body ages, a study suggests.

King's College London scientists compared key ageing DNA with the number of moles in a study of 1,800 twins.

They found the more moles a person had, the more likely their DNA was to have the properties to fight off ageing.

The study, in the Cancer Epidemiology Biomarkers and Prevention journal, contrasts with the link between a high mole-count and high skin cancer risk.

In the study, researchers found those with more than 100 moles had longer telomeres than those with fewer than 25. The difference between the two mole groups was equivalent to six to seven years of ageing.

Lead researcher Dr Veronique Bataille said: "The results of this study are very exciting as they show, for the first time, that moley people who have a slightly increased risk of melanoma may, on the other hand, have the benefit of a reduced rate of ageing.

"This could imply susceptibility to fewer age-related diseases such as heart disease or osteoporosis, for example. Further studies are needed to confirm these findings." Link
