Skin cancer rates are rising across Los Angeles County, and health experts are reminding residents why sun safety tips are always important.
Skin Cancer on the Rise
Data from the California Cancer Registry shows melanoma diagnoses increasing steadily over the past decade. Dr. Angela Reyes, a dermatologist with City of Hope in Duarte, said in an interview that too many residents still underestimate the danger of unprotected sun exposure. “Any tan is a sign of skin injury,” Reyes said. “We see people in their 30s and 40s with advanced skin cancers that could have been prevented.”
Fair skin, a history of blistering sunburns, and regular outdoor activity are the most significant risk factors. The American Academy of Dermatology estimates that one in five Americans will develop skin cancer in their lifetime, making prevention efforts critical.
The Role of Sunscreen
Sunscreen remains one of the most effective defenses. Dr. Reyes recommends using a broad-spectrum product with an SPF of at least 30 and applying it 15 minutes before going outdoors. A full ounce is needed to cover the entire body adequately.
Reapplication is essential, especially after swimming or sweating. “People often forget to reapply every two hours,” Reyes said. “Even short lapses leave skin unprotected.”
Covering Up and Avoiding Peak Sun
Protective clothing can further reduce exposure. Long-sleeved shirts, wide-brimmed hats, and sunglasses that block UV rays help shield skin. Light-colored fabrics reflect heat and keep the body cooler during outdoor activities.
Health officials advise limiting time outside between 10 a.m. and 4 p.m. when UV radiation is strongest. Children are especially vulnerable. “Early sunburns greatly increase lifetime risk of melanoma,” Reyes said.
Recognizing Warning Signs
Early detection improves treatment outcomes. Residents should examine their skin monthly for changes in moles or new spots that look different.
The Skin Cancer Foundation advises watching for moles that grow, change color, bleed, or itch. Non-healing sores are another warning sign. Reyes recommends annual skin exams by a medical professional. “If you spot anything unusual, get it checked promptly,” she said.
Local Screening Resources
Several local organizations offer screenings and education. The LA County Department of Public Health provides free skin checks for uninsured residents through community clinics.
City of Hope will host its annual Skin Cancer Screening Day in August. Appointments are available to the public.
