Field cancerization in the face of a 44-year-old female welder
Welding generates ultraviolet radiation and has been suggested to cause skin cancer. However, it remains questionable whether welding is in fact causally associated with the development of skin cancer. We report on a 44-year-old female with ten years occupational experience as a welder, who developed multiple squamous cell carcinomas located exclusively on the right side of her face. During welding she had experienced numerous facial burns limited to the right side. This marked anatomical relationship between exposure and illness supports a causal association between welding and skin cancer.
