UV exposure linked to skin cancers

The French National Agency for Food, Environmental and Occupational Health Safety (Anses) has confirmed a direct connection between occupational exposure to ultraviolet (UV) rays—both natural and artificial—and three types of skin cancer: squamous cell carcinomas, basal cell carcinomas, and melanomas.

Risk affects millions of workers

Approximately 3.5 million workers in France are exposed to solar UV rays, putting them at risk of developing occupational skin cancer. This includes jobs in sectors like construction, agriculture, and outdoor services, where prolonged sun exposure is common.

Factors influencing UV risk

The risk of developing skin cancer from UV exposure depends on several factors, including the duration of time outdoors, the intensity of sunlight, and reflective surfaces such as water or snow. Even brief or intermittent exposure, such as supervising children or working on restaurant terraces, can increase the risk.

Global impact of UV exposure

The World Health Organization (WHO) states that UV exposure is the leading cause of skin cancer, responsible for 120,000 deaths worldwide each year. In Europe, countries like Germany and Belgium recognize and compensate for occupational skin cancers, while France lacks a formal system for identifying and compensating such cases.

Underreporting in France

In France, occupational skin cancers are underreported and under-recognized, partly because there is no official list of occupational diseases that includes these cancers. Between 2013 and 2024, only 137 cases were reviewed by a regional committee, with 40% receiving a favorable opinion.

Artificial UV exposure also a concern

Some workers, such as welders and farmers, are exposed to both natural and artificial UV rays. Artificial UV exposure from welding, for example, can lead to ocular melanoma. Farmers may be exposed to both types of UV rays during fieldwork and when using UV lamps for disinfection or pest control.

Recommendations for prevention and detection

Anses recommends creating a specific list of occupational diseases related to UV exposure and the associated skin cancers. It also calls for companies to implement organizational protection measures, such as limiting sun exposure and rescheduling tasks during high-risk periods.

Early detection through skin exams

To improve early detection, Anses emphasizes the importance of regular skin examinations by occupational physicians. These exams can help identify skin cancers at an earlier stage, improving treatment outcomes. Physicians must be trained in dermatological assessments to ensure accurate diagnosis.
