Skin Cancer More Aggressive with Fewer Moles Present

People who have fewer moles may be at higher risk for aggressive melanoma than those with more numerous moles, according to a new study. Researchers reviewed the charts of 281 patients with the skin cancer melanoma who visited a Boston hospital in 2013 and 2014. Of all the patients, 89 had 50 or more moles, whereas the remaining 192 had fewer than 50 moles.
