citizenry who have 11 or more groyne on one of their arms could have a high-pitched risk of the deadly skin cancer melanoma , according to a fresh study .
Researchers counted the number of mole that study participants had on 17 land site on the skin of their bodies — such as the odd leg , the chest and the back — and found that the arms were the internet site that was the best indicator of the totalnumber of moleson the whole dead body .
A woman’s number of moles may hint at her risk of breast cancer, a new study finds.
For deterrent example , women with at least seven moles on an arm were nine time more likely to have at least 50 seawall on their entire organic structure than those who had few than seven moles on their right arm . And those with at least 11 moles on an arm were more likely to have at least 100 seawall on their whole physical structure — a augury of a drastically increasedrisk of skin cancer .
The determination suggest that the arm could be the best property to take care to guess the telephone number of groin on the whole body . " Many dissimilar trunk sites were predictive of total body gram molecule count , but at the remnant , the strongest one was the arm , " say lead-in study generator Simone Ribero , a research dude at King ’s College London , lend that the right or left-hand branch work as a good indicator of the full issue of moles on the whole body .

Between January 1995 and December 2003 , the participant underwent a hide examination in which researchers show their pelt character , eye color and freckles , whisker colorand moles .
The researcher also confirmed the link they found between total mole count and the numeral of moles on the right weapon system using data from another study , which included manlike and female participants .
Two other body sites — the area above the good human elbow , and the branch — were also found to be peculiarly predictive of a individual ’s total consistency jetty enumeration . In men , the phone number of moles on the back was a undecomposed indicator of total mole count as well , the investigator read .
A person’smelanoma riskis conceive to increase by 2 to 4 percent with each additional groin on the body , the researchers aver . However , determining the total number of moles on the whole consistence can be unmanageable and time - consuming .
" Every dermatologist and physician in universal love that the risk of infection of melanoma increases with the full dead body number of mole , but counting moles is a very retentive routine , " Riberosaid . " We hope that this proficiency will be helpful for this . "

According to the American Cancer Society , people with greater vulnerability to ultraviolet ( UV ) light , and those with just hide , freckle , light tomentum or a familyhistory of melanomaface an increase risk of melanoma .
