It’s skin cancer prevention season, and Ohio State experts are here with tips for staying safe in the sun all summer long. While some people are genetically predisposed to skin cancer, doctors believe that the majority of cases are caused by UV or sun exposure — which means that they can be prevented. “That's why we focus so much on sun protection, and that includes using a sunscreen with SPF of at least 30 that is water resistant,” says Natalie Spaccarelli, MD, a dermatologist at the OSUCCC – James’ Pigmented Lesion Clinic. Along with sunscreen — which should protect against both UVA and UVB sunrays — Spaccarelli has a few other recommendations for enjoying the summer without raising the risk of skin cancer. “Another important part of sun protection is trying to avoid sun during peak hours, so 10:00 a.m. to 2:00 p.m. is a good time to try to avoid the sun if you can,” she says. “Also, wearing sun-protective clothing and hats can provide an additional layer of sun protection on top of the sunscreen.”
