Dr. Ronald Hansen has an eye for skin cancer. Hansen, who is a consultant for the Mayo Clinic in the Northeast Valley and on staff at Phoenix Children's Hospital in Phoenix, said dermatologists can "lock in" on a mole or area of skin that looks abnormal. "All of the people I train and those at Mayo used a hand-held microscope to see the structure of a mole," he said. "In seconds, we can say, 'Those three pieces of clover shape are normal,' or say, 'There are changes in the pigment network and this one has to come off.' "
