Summary
Marathon runners show increased risks for skin cancers, including malignant melanoma. Reducing UV exposure through protective clothing and sunscreen is crucial for athlete health.
Area of Science:
- Dermatology
- Sports Medicine
- Oncology
Background:
- Marathon running's popularity is rising, with perceived health benefits potentially masking risks.
- Previous observations noted malignant melanoma in ultramarathon runners, prompting investigation into risk factors.
- Potential triggers include ultraviolet (UV) radiation exposure and exercise-induced immunosuppression.
Purpose of the Study:
- To evaluate risk factors for malignant melanoma in marathon runners.
- To compare anamnestic, phenotypic, sun-related, and clinical variables between marathon runners and a control group.
Main Methods:
- Examined 210 athletes (marathon runners) and an age- and sex-matched control group.
- Assessed variables including sun sensitivity, melanocytic nevi, solar lentigines, and lesions suggestive of nonmelanoma skin cancer.
- Correlated findings with training intensity and sun protection habits.
Main Results:
- Marathon runners exhibited more atypical melanocytic nevi, solar lentigines, and nonmelanoma skin cancer lesions compared to controls.
- These dermatological findings correlated positively with increased training intensity.
- Inadequate sun protection was common, with only 56.2% of runners regularly using sunscreen.
Conclusions:
- Marathon runners face a heightened risk of malignant melanoma and nonmelanoma skin cancer.
- Athletes should minimize UV exposure during training and competition.
- Recommendations include scheduling activities during lower sun exposure periods, wearing protective clothing, and consistent sunscreen use.
