From the Research
Occupational exposure to painting is a significant risk factor for lung cancer, as evidenced by the most recent and highest quality study, which found an increased risk of lung cancer in painters, particularly those with longer durations of employment 1. The risk of lung cancer associated with painting is attributed to exposure to various chemicals, including volatile organic compounds (VOCs), solvents, heavy metals, and particulate matter.
- Key factors influencing the risk include:
- Type of paint used, with oil-based paints generally being more hazardous than water-based paints
- Ventilation conditions, with poor ventilation increasing the risk of exposure
- Duration of exposure, with longer durations associated with higher risks
- Use of personal protective equipment, such as respirators, gloves, and proper clothing, which can reduce the risk of exposure According to the study published in 2021, the odds ratio (OR) for lung cancer in painters was 1.30 (95% CI 1.13-1.50), with the association being strongest for construction and repair painters 1.
- The study also found evidence of interaction on the additive scale between smoking and employment as a painter, highlighting the importance of considering both occupational and lifestyle factors when assessing the risk of lung cancer. Other studies have also reported an increased risk of lung cancer in painters, with a meta-analysis published in 2011 finding a summary relative risk (meta-RR) of 1.35 (95% CI 1.29-1.41) for lung cancer in painters 2.
- However, the most recent and highest quality study, published in 2021, provides the strongest evidence for the association between occupational exposure to painting and lung cancer risk 1.
