South Florida has one of the highest UV indices in the continental United States, regularly reaching “extreme” levels (10+) during summer and “very high” levels year-round. For the millions of people who live here, this creates a significant and cumulative skin cancer risk that requires consistent prevention habits.
Skin Cancer in South Florida
Skin cancer is the most common cancer in the United States, approximately 9,500 people are diagnosed every day. The three primary types:
- Basal cell carcinoma (BCC), the most common, rarely fatal, caused by cumulative sun exposure
- Squamous cell carcinoma (SCC), second most common; can metastasize if neglected
- Melanoma, the most dangerous, responsible for the majority of skin cancer deaths
For South Florida residents, risk is elevated by year-round high UV index, outdoor lifestyle culture, and lower awareness of risk among individuals with darker skin tones (skin cancer occurs in all skin tones; late diagnosis in patients with darker skin is a serious clinical problem).
Evidence-Based Prevention
Sunscreen: – SPF 30+ minimum for daily use; SPF 50+ for extended outdoor activities – Broad-spectrum protection (blocks both UVA and UVB) – Apply generously, most people use 25–50% of the effective amount – Reapply every 2 hours when outdoors, immediately after swimming or sweating
Protective clothing. UPF-rated clothing is more reliable than sunscreen for prolonged outdoor exposure. Wide-brim hats protect the scalp, ears, and neck.
Shade-seeking. UV radiation is most intense between 10am and 4pm. South Florida’s UV index at noon in July is approximately equivalent to Saharan Africa.
Annual skin examination. Dermatologists recommend annual full-body skin checks, particularly for people with significant cumulative sun exposure or a family history of melanoma.
Self-examination. Monthly self-exams checking for the ABCDE signs of melanoma catch many melanomas at early, treatable stages.
