UR medicine is offering free skin cancer screenings Saturday May 31 from 8 a.m. to noon on the second floor of the ambulatory care facility in the dermatology suite at Strong Hospital. Anyone is eligible for the free check up.
"It's a service for people to come in and have their skin checked who otherwise might not have," Dr. Brown said.

Also, dress in loose-fitting clothes and grab a four inch brimmed hat to wear in the sun. These tips combined could protect your skin and prevent sun damage.
